eBay hard parts have gotten a hell of a lot better and now everyone realizes they've been getting ripped off for parts that have no moving parts you should do a video on intercoolers talk about getting ripped off
We install headers almost daily & we also have a dyno jet. You are correct on the power output is equal. When a customer comes in with ebay headers we charge a extra 2 hours on the install ($220) because THEY NEVER FIT!!! We have to reem out flange holes on ebay headers all the time. God forbid a customer brings in a long tube + y-pipe ebay combo because the y pipe always needs a ton of persuasion to align which more often than not requires cutting and welding. Moral of this story, what you save on buy ebay headers is spent on installation so it winds up costing the same. I say buy name brand because in that case you get customer service from the manufacture and a real warranty not a Wuhan Warranty!
I was just going to say this about fitment and buying cheap headers. This why I went with kooks 1-7/8" on my 08 Vette. I want it all to fit right and I don't want them to hang low like all the cheap ones do
The biggest thing I learned is anything naturally aspirated under 550HP doesn't need dual 3" exhaust. The 2.5" didn't trade anything up top and gained torque down low over the 3".
Good point. I also noticed that all of the testing takes place above 3500 rpm. So for a street car not in the rpm nosebleed section, you may be able to do pretty well with just a good set of manifolds.
Yep, I've ran the inexpensive headers on my vehicles for years. MUCH appreciate your sharing and work on this video, backs up what I've always said and felt, and I certainly will use this to share! When you look at the price difference, troubles or longetivity isnt much a problem to me, when I can buy multiple inexpensive sets vs just the one
Very cool to see the differences from each type of header. Id like to see it one step further with other bolt on mods. Such as cai, tb, and aftermarket intakes. Nice work regardless!
I love data.Thanks Richard.What surprised me was the fact that even though it's just headers there really wasn't as much of a gain over factory manifolds.
If DNA isn't supplying you with the stuff you need for these videos, they need to because you probably just sold over 100 long tubes from them. Count me as 2.
I put the same DNA headers on my 15 SS camaro I like them they are nice for the price but if I had the $1200 for Kooks I would've bought them. Great vid
I bought some headers for 300$ seen the unbranded same design! For 109$.. on eBay just doesn't have the sexy name plate on it like mine.. I've been needing this video basically so I can sleep better.
My DNA headers had straight, thick flanges and fit great with no leaks but upgraded the gaskets just to make sure. $200 for good looking headers. I am happy with them for sure.
Having run many inexpensive headers ($89 i think was the cheapest and they burned #3 wire off every other month) i was thinking of the fit and customer service through most of this video. Great job hitting all the points!
I like that you do apples to apples stuff.... 5 decades of hearing how this manifold for intake or exhaust will add "25% HP gain! I love to see the actual practical numbers. Also... I put the camaro cast manifolds on my 5.3 in an LS conversion and they added about the same power.
What year of Camaro and what did you swap the engine into? I'm going to swap a 5.3 in a 92 Sonoma with 4WD. I still have the stock manifolds, but I am just wanting to plan ahead and see what other people have gone with.
I’ve looked at EBay headers. I liked the fact that they were stainless, but read the reviews about figment, and durability. They weren’t too convincing. I ended up getting a good set of Schoenfeld circle track headers, cause I wanted low to mid range torque. I had to remove my AC box to get them in, but once I did, the headers fell right into place. For a street rod that I only drive in goo weather, it was worth it. I gained ground clearance. My original mass produced headers didn’t give me that. I don’t have to lift the engine to remove or install them, and they actually gave me a pretty noticeable kick in the butt, when I drove it.
Thanks for the rundown on the results! Def great info to know! Based on that data, as long as the fitment of the inexpensive headers is acceptable, then I wouldn't have any issue with using them. From a cost perspective, they're pretty much disposable.. but nobody want to replace stuff "just because". So, it would be interesting to hear from others about their longer-term experience with the lesser priced parts with regard to rusting, reliability of the welds (life without leaks), as well as discoloration. Ceramic? Blankets? Bare? I imagine that Richard would excel in an American Sign Language course! Thanks again!
@@johnparrish9215 Plus OEM cast manifolds always lend themselves to turbos lol. It'd be interesting to do a stock manifold test, from the various cast items, to LS7 etc.
I agree the factor manifold performs well. I think this may be the same factory manifold that is used on the 5.3, 6.0, etc. That means it is meant to flow much more than the 4.8L. Because on the 4.8 with a high flow head, cam, etc., it just doesn't seem like much restriction from the factory manifold, even with the high flow head and cam.
Great video! Thanks for the testing. For further improving these videos: putting a table with all the results in one shot after the testing would be really nice.
Kinda, but they hit one hell of a brick wall once you go above what they were designed for. But the lack of leaks, ease of installation etc. is very tempting.
Another great video from Richard, I would go with the name brand Richard didn't mention it but quality thickness of the tubing ect makes a difference of longevity
Since I started getting involved in higher performance domestic 8 cylinders, I've always heard about how headers were something you don't skimp on. I couldn't get over the fact that a company here in the US could make something for $1100, while a china company could make something almost identical for $250. It's a simple bunch of steel tubes haha. I have bought more expensive domestic headers and they all require modification to clear plugs, frame rails, starters. I'd feel much more inclined to go smacking a cheap set of headers than something I just spent a paycheck on haha.
Same. From all of the UA-cam videos Ive watched of guys installing high dollar headers, they ALL run into fitment issues. So I might as well get some cheap shit so I can just pay a buddy to deal with the headache. XD
I bought the ebay headers because the stock exhaust manifolds on my vortec engines shrink and break the bolts off in the heads. The ebay headers fit perfectly, thick flanges and they work great with no leaks.
What you should have mentioned is the benefits from long tube headers down low when you take off from the stop light. For a Heavy vehicle like a truck, there is where they really shine.
Nice results! My question would be the gains of the cheap turbo headers vs the high$$$ brands. 3”v band collector style. I’m curious to see the pros and cons of the inexpensive turbo headers. Keep up the awesome content!
Can’t believe how good the eBay headers did compare to a well known brand. I’m impress but I do feel a bit skeptical about the length and how it will hold on being pushed to its limits on a daily driver. Outstanding video bro bro, loved every detail you put out on each headers and motors. 👌🏽💯
I put Chinese headers on a f150, had a hard time on a couple ports getting bolts in because if the tube being so big and no room for the head of the bolts. Thanks for the video
Tests that we like to see! Is it worth the money to buy aftermarket big $ parts or just get a cheap setup! Seems header that cost 700 to 1000 plus are not worth the extra coin!
Another great video ! Thanks for taking the time to educate us !! I'll bet this same test on a 6.0 liter would be more exaggerated differences.. hmmmmmm
I have used many sets of what they call the cheap eBay stainless steel headers and to be honest I've had excellent results with them. Back in the days the headers in the US you could not keep gaskets on them the stainless steel cheap eBay headers hold the gaskets very well you can even use stock gaskets with them. I would even put them up against our well-known brand hooker
They have even cheaper on Amazon. Heck they probably have plastic headers on the net somewhere. Anyhow Longtube headers will outperform the shorties in the whole rpm range. Shorties are for fitment issues
Cheap works great at 1/4 the price, if something happens just buy another pair. I bought a set of long tubes 2 inch by 3 inch collectors stainless steel, paid less than 400... gained 46 hp on 2016 LT1.
The price you pay is for build quality and longevity. If you want something to build a cheap race car, go cheap. If you have a Corvette chillin in the garage that you wanna make some power with, go expensive, especially if you plan on keeping it a while
FINALLY a 4.8 I’m going to be putting together a high compression 310ci engine and can’t find any info on small n/a LS builds That 4.8 should push over 450 with a fast102 don’t you think?
Am currently planning a header install on my 06 Vette. Was looking at Kooks with X pipe. May have to look at other (Ebay) options. Thanks for the video.
Defiantly what he said at the end....{the fitment ) and quality but me I have a C5 I think id try ebay before spending a outrages amount of money on name brand
I brought some headers for about 250 came with the header y pipe and extension after the y.they didn’t fit just becouse the extension hit the cross member for the trans but it was nothing mufflershops can’t fix. Im really happy with them and haven’t had any problems love them tbh cammed out 4.8 I mean 1 7/8 from good brand header Is not a different from 1 7/8 from a budget header right. Mesurment is the same
I guess it would depend on how many sets of the cheap ones I could get for the same price as the name brand and how easy they are to put in. I really don’t like doing things more than once.
@@dj4monie tiny bit more complex? lol. you also gotta think about how you'd cool the intake charge in such a setup and the piping involved, plus the packaging and weight involved especially if the engine is front of the driver.
Awesome content I have the DNA system on my Tahoe with their y-pipe, my curiosity is does the short collector make a difference to power on both sides of the fence compared to the longer collector. I do know it does affect scavenging but how much of a loss
I hate the horrible raspy noise that stainless steel exhausts make, titanium makes the engine scream, shame there are no cheap ti exhausts on ebay, it would probably be waisted on a LS though.
Richard I’m sorry to ask on this video but have you ever tested or think you might be interested in testing low budget aftermarket build it yourself engine management. Like the micro squirt or maga squirt? Supposedly good from 1 cylinder to whatever number you have.
I have a set of Ebay headers on my L67 Grand Prix, they come 3" collector, and I put a 3" Flowmaster cat, 3" piping right to the single Flowmaster 44 muffler, with dual 2.5" exits. It sounds super deep, and crispy.👍👌🇨🇦🔥🔥🔥
Included with your voice over a bar graph with all the hp and torque differences together would be easier to understand. I like the videos but sometimes it takes a while to get to what I came for and I miss it. Then I catch myself having to replay parts to gather all the feedback and compare them in my head. LOL!!
I wen with dna headers on my mustang they fit great and work fine had them for a year of hard driving no corrosion to be seen so i think they will last till i do somthing like turbo
Given how much power Freiburger DIDN'T lose by smashing headers with a sledgehammer, I think Ebay headers will be just fine for their length. What you get with a name brand is quality, fitment, longevity, and approving nods from the grey-beards. Fitment is no joke; sometimes you discover that the cheap headers want to occupy the same location in space-time as a control arm bushing (because they were mocked up on a 4x4 model and your 2wd is different). But Ebay has a fitment return and refund policy, so there's that. Either route is valid, so long as you know what you are and aren't getting for your money.
Awesome! The exact review I was looking to help me justify replacing my shorties with long tubes. Any chance you’d do some long tube size comparisons? 1 5/8 vs 1 3/4 vs 1 7/8 on the LS3?
Richard Holdener, I saw that and that was great, but the collectors were also different sizes (2.5” vs 3”). This adds another variable in the test. Still... awesome information. I’m just debating if I really need to go from 2.5” to 3” coming out of the headers...
My short tube headers were very thin where the exhaust piping bolted up to them. The exhaust guy did great welds but at the confluence of the very thin wall SS and the aluminized tubing it was a difficult weld. Remember these do not have a flange just a short end of the tube that clamps to the headers. Flange thickness at the head was adequate and I had no issues with them leaking there. Spark plug access was fine but the set up needed a set of ceramic boots on the wire to keep from burning them. Don't forget to add the cost of the wires to the change over.
I would like to see gen 3 hemi stuff. With hemi swaps not many options from from stock. Ram logs to jeep logs and car logs... srt stuff and very few aftermarket. How restrictive are the stock logs. Also eagle head swap is it worth it? Factory 392 vs stroked 5.7 392 is one better than the other.
USA header manufacturers roughed him up over this video but he still published it. RH the MVP.

I have set DNA headers on wife’s suburban for couple years. Been very happy with them. Next up will be a truck cam.
Awesome video! What did I learn? Headers don’t make as much power as people think they do.
Bottom line is LS engines breathe very well even stock
On a stock engine no, but on a modified motor they do and more.
You missed the point. Peak power - no. Bottom end gains - hell yeah
The Jury's In ! Best Bang For the Buck on stock is correct cam and springs that still work with the Stock Torque Converter

Price does matter....in case you are all wondering...Cost me around 350 total with the long tube headers, mid pipe, and y pipe assembly...
$1500 to $2000 for headers is just to much for a stock engine with just a cam upgrade!

only to gain 20hp if that
its too much for anything that doesnt make 2000+hp and need to be made out of titanium

What you get with a name brand is quality, fitment, longevity, and approving nods from the grey-beards. Fitment is no joke; sometimes you discover that the cheap headers want to occupy the same location in space-time as a control arm bushing (because they were mocked up on a 4x4 model and your 2wd is different). But Ebay has a fitment return and refund policy, so there's that.
Either route is valid, so long as you know what you are and aren't getting for your money.
Can i see a video on turbo headers see what works better: spool speed, egt, and heat.
Personal choice, Summit Racing... I'll get what I want plus customer service
Just ordered my ebay long tubes thanks
Whats your favorite rear main seals
Thumbnail is awesome Richard ! Lmao
This made me subscribe. Old school small block guy. Trying to keep up. Surely this will help. Lol
Awesome! The exact review I was looking to help me justify replacing my shorties with long tubes. Any chance you’d do some long tube size comparisons? 1 5/8 vs 1 3/4 vs 1 7/8 on the LS3?
That would be a excellent test! I always told the smaller the pipe more torque. The bigger the pipe, more horsepower. Would love to find out
the vid has 1 3/4 vs 1 7/8 on the LS3
Richard Holdener, I saw that and that was great, but the collectors were also different sizes (2.5” vs 3”). This adds another variable in the test. Still... awesome information. I’m just debating if I really need to go from 2.5” to 3” coming out of the headers...
Does not look like the expensive headers are justified, unless warranty on structure is better
My short tube headers were very thin where the exhaust piping bolted up to them. The exhaust guy did great welds but at the confluence of the very thin wall SS and the aluminized tubing it was a difficult weld. Remember these do not have a flange just a short end of the tube that clamps to the headers. Flange thickness at the head was adequate and I had no issues with them leaking there. Spark plug access was fine but the set up needed a set of ceramic boots on the wire to keep from burning them. Don't forget to add the cost of the wires to the change over.
Richard do you have any cams and springs for a 2005 GMC sierra 6.0 L engine that you want to sell?
can you comment on the benefits of 17/8 and 2.0 diameter header pipes
on what application-you don't need 2-inch headers on the ls motor tested
I would like to see gen 3 hemi stuff. With hemi swaps not many options from from stock. Ram logs to jeep logs and car logs... srt stuff and very few aftermarket. How restrictive are the stock logs. Also eagle head swap is it worth it? Factory 392 vs stroked 5.7 392 is one better than the other.
Would equal length shorty headers make a difference????
nope
Awesome test! Keep up the good work. I think china owes you some money for all the testing.
