My buddy has a 06 cateye, he’s got speed engineering long tubes, going into 3 inch true duals with high flow cats, bullet mufflers, and an x pipe. In my opinion it sounds awesome! It has a quiet idle, but when you step on it or rev it, it gets really rowdy, pretty poppy, but not raspy at all, sounds really great at full throttle too!
I bolted shorties on my 4.8 because, well, 4.8. No performance boost but sounds great. Easy Peasy, 3 hrs. Worst part was the manifold/ cat bolts. One manifold bolt broken, used an extractor socket, and chased threads on the other sid. I really enjoy seeing you have fun with your babies. Sound mean!
With your post cat o2s you can just unplug those but your main o2s are necessary for the health of the motor and getting a wideband o2 will make tuning alot easier
very good install man. I got lucky with my old 04, only 1 broken stud, and I had a stud retraction socket I put on it and spun it right out. gonna assume you welded nuts to the broken studs or did the EZ out and drill method. it took maybe 4hrs to get it all together, went pleasantly amooth. I'd love to put these on my 05 SS truck with a Corsa exhaust system. That frame on this GMC looks impeccably clean, what a great looking truck.
Can you tell me if the O2 sensors would have something to do with making your truck run bad because my truck had 4 of them but I only put two one in each header
Haha the old broken header bokts..boots... I have done about a dozen header and custom exhaust swaps on these trucks... I always get them out while the heads are hot. Also if you bust the steering bolt loose you have way more room dropping the driver side in. I ended up buying a builder's kit and making my own cat back. Also welded all the joi ts and put on v bands... the entire exhaust comes out only removing 4 v bands and nothing else. Good stuff man welcome to the club. The performance mods will never end now I warn you! Also some are chromosomes header bolts 12 point head will be worth the 35 dollar price.. other bolts rust and break. As far as the smell I put a 3" kooks 300 cell high flow cat where the y pipe merges and a 14" magnaflow Muffler and it sounds perfect with no smell. Also a solid custom tune would be good. Canned tunes are not worth the money. FYI the port in the back is for a wideband...
These Speed Engineering plug wires are specifically designed to not burn on the headers. I’ve had Speed Engineering longtubes and plug wires on my LS C10 for a while now and they are perfect
You should put a Moroso Spiral Flow race muffler on it, it will quiet it down just a little bit and give it a nice deep smooth tone. I had one and a 2011 Silverado with a 5.3, it did still have cats but it sounded Amazing. Anyways I love the videos man, keep up the Awesome work👍🏻💯
I can’t wait til you get a cam for chomper! Honestly if it was me I probably would have put the headers on while/ after the cam so you could have got it tuned for everything all at once.
Same I don’t like the clap I have the same set up I’m thinking of getting another muffler .. i only found one sensor location for the sensor 2 is that normal
Make sure you get the front camber fixed. My truck was like that after i bought it and it chewed thru the sidewalls of my first set of open country tires before i fixed it
Hey lmfscrew just curious why you didn't go with the 1 7/8 inch ling tube? Are they too large for a stock truck or just what you wanted? I'm looking at getting them for my 99 with a truck norris cammed 4.8.
I just bought the same year color z71 ext cab truck! Bout to slap some headies and exhaust on her thought it would be hard to get some on 4wd but this is what i wanted to see
Just zip tie the back o2s up out of the way until you tune. Might avoid cel that way. Truck just needs to see a difference between uppers and lowers to verify “cats are working “
@@ryanleach3936 it can. Only thing the rear o2 does is measure efficiency. Just needs to see that the air behind the cat is cleaner. Seen it work. Have seen it also not work
Was planning on speed engineering .was just concerned about 1-7/8 rubbing. Couldn't really see too good but what air intake are you running. Was thinking about going k&n
What are you going to do with the rear O2 sensors I got the same headers but am kinda lost why they only put 1 O2 bung past the headers? I don't think you would even be good for a wide band cuz it's only going to see Bank One
Always do exhaust manifold bolts when the engine is hot. Dorman makes a bracket that bolts to the head and holds the manifold down. Been running one for ever on the truck.
I have this same exhaust but mine leaks from the ears on the passenger side and from most of the clamps which idk why since they are fully tighten and idk why it’s doing that
Fudge I have a stock 2010 Chevy Silverado 1500 4.8l v8 should I do it I really want to but am a bit clueless but have some friends that will help me out
Quick question I’m trying to order my longtube headers already but I can’t find long tubes for a 4x4 I don’t know if it matters or not I’ve always had a 2wd I’m all new on the 4wd
Long tubes into that 3” allllllllllllllllllllll the way back! Or have a shop take out that “y” pipe and run the headers some high flow cats and true dual??!!! That would be my favorite and would make Chomper live up to his plate! 😈
I’ve got an 05 Silverado with a full 3 inch system with the same headers and mines cammed with some other goodies if you want an idea of what it may sound like? I personally am not running mufflers and it sounds nasty 😂 I like it but everyone has their own opinion but the 3 inch system definitely sounds and performs amazing! Been following your builds for a long time now and I love what you’ve done with chomper 😎
A friend has a 69 GTO with headers , no mufflers only drives it in the summer, sounds good , good enough to draw ' attention ' , the boys in blue liked it so much they had to tow it in for a closer look , and cite him a ticket for no mufflers ☹️

hey my name is maddux too lul

Did the oem y pipe fit, or what did you use for a y pipe with shorties?
@@Pitman556 oem cats to from manifolds muffler. Installed BMRP muffler with double exhaust out back and it looks and sounds old school sick.
Chomper is sounding nasty now! Can’t wait to hear it with a full exhaust!
You need the cams now she'll be rowdy
Cam*
@@Kennybeachum was about to say that lol
@@markpalazzolo1463 heh
Thought he already had the cam or is this an older video?

Thanks your 2 videos helped alot on my long tube header installation !!!

Gonna sound awesome! Im gonna love this truck even more now!!! 🔥
It’ll just sound good, but the rims ruined it.
@@fintansky9369 yeah. I like the other ones 100 times better

yessir been watching you for a while now and i am so glad to see you finally digging into some motor work, keep up the great work bro

I run the speed engineering 1 7/8” long tube headers and catless Y pipe on my 2016 6.2L 8 speed Sierra and absolutely love them
Just curious do you have OBDII emmsions testing ?
@@bigstunner1381 No sir

I got all of my manifold bolts out while the engine was cold except for the very back bolts on each side they were already broke lol
Put DEI heat wraps on the plug wires to prevent burning or heat degradation of the boots and wires. Plus they look great.
These Speed Engineering plug wires are specifically designed to not burn on the headers. I’ve had Speed Engineering longtubes and plug wires on my LS C10 for a while now and they are perfect
Ceramic boots
does this bolt on to the rest of the stock catback exhaust via the same type of flange or is welding required
Just bought these headers. can’t wait
Should have definitely put header wrap and spark plug wire covers. That engine bay temp is gonna be hot as hell!
You should put a Moroso Spiral Flow race muffler on it, it will quiet it down just a little bit and give it a nice deep smooth tone. I had one and a 2011 Silverado with a 5.3, it did still have cats but it sounded Amazing. Anyways I love the videos man, keep up the Awesome work👍🏻💯
I was literally wanting to run those same headers and a carven on my 03 Silverado, I’d love to hear what that sounds like. Keep up the good vids man!
I can’t wait til you get a cam for chomper! Honestly if it was me I probably would have put the headers on while/ after the cam so you could have got it tuned for everything all at once.
These are denali rims but what size tires? I love the fit and even look on your truck. Very classy
What spark plug wires did you throw in there
its so crazy looking underneath that truck. im from ohio and my 2014 is rusting like hell
Good Job chase! Interested in how you fixed the broken bolt issues.
I've got carven tr's with X pipe and it sounds amazing on my 5.3. Still loud but takes most of the "clap" out.
Same I don’t like the clap I have the same set up I’m thinking of getting another muffler .. i only found one sensor location for the sensor 2 is that normal
What have you done to your dash cluster? Looks so much better than the stock one
How’d you get it to clear your drive shaft?
Welder is your best friend. I had to extract like 5 of them on my 4.8 I used to have
And does the headers and y pipe bolt up to factory exhaust or modifications needed?
What brand of spark plug wires did you use? Wanna try msd but liked the way the ones you used fit
Any update
Do I need the longer spark plug wires or can I use the oem ones? I have a 2005 chevy 5.3
What kind of o2 sensors did you run and did you tune it yourself?
Are they still working good for you? Hows the line on pass side?
What's was the clearance between your driver side header and your lower steering shaft? Any bumpage?
In doing the same thing. Question, how did you deal with the o2 sensor for after the cat
Did you have to cut anything off the transmission cross member to make them fit? Debating doing this on my 00’ 2500
Those stock wheels look so much better then that other set you had one by far👌🏼
Would it be easier to just lower the cross member to get the y pipe in?
Make sure you get the front camber fixed. My truck was like that after i bought it and it chewed thru the sidewalls of my first set of open country tires before i fixed it
Why didn't you use anti-seize on the new header bolts?
How many o2s does chomper have and how many did you actually plug in to exhaust?
Best UA-camr
hard to see in the vid but i think i see the transfercase...is the truck 4x4?
How much they charge u for the tune
Hey man how did you install o2 sensor for check engine ?
Hey lmfscrew just curious why you didn't go with the 1 7/8 inch ling tube? Are they too large for a stock truck or just what you wanted? I'm looking at getting them for my 99 with a truck norris cammed 4.8.
What did you do with the o2 sensors??? I a told the truck willl not perform properly something to do with the O2 sensors
I just bought the same year color z71 ext cab truck! Bout to slap some headies and exhaust on her thought it would be hard to get some on 4wd but this is what i wanted to see
What size tip you running.? I got long tubes just ain’t put them on yet
Just zip tie the back o2s up out of the way until you tune. Might avoid cel that way. Truck just needs to see a difference between uppers and lowers to verify “cats are working “
Does this actually work?
@@ryanleach3936 it can. Only thing the rear o2 does is measure efficiency. Just needs to see that the air behind the cat is cleaner. Seen it work. Have seen it also not work
Can you put the o2 sensors back in just so the monitors can run for inspection?
Was planning on speed engineering .was just concerned about 1-7/8 rubbing. Couldn't really see too good but what air intake are you running. Was thinking about going k&n
I’d love to see you do this with Larry, I have a truck similar to it and want to put long tubes on mine.
Where did you get the y pipe from?
Just curious did it not throw a code for the check engine light, since you added headers?
Headers don’t change anything because there are still o2 sensor holes in these headers.
@@socal_c10 thank you!
Use a vibrant resonator you won’t regret it. Will deepen your tone
What are you going to do with the rear O2 sensors I got the same headers but am kinda lost why they only put 1 O2 bung past the headers? I don't think you would even be good for a wide band cuz it's only going to see Bank One
can i get the link to the headers and plug wires???? it looks and sounds absolutely amazing and i would like to copy this on my tahoe
How much was it to cam it after buying the cam and stuff needed
Always do exhaust manifold bolts when the engine is hot. Dorman makes a bracket that bolts to the head and holds the manifold down. Been running one for ever on the truck.
Did he/you both gaskets, the one that came with it and the ones he/you bought?
Vv cool. I can’t wait to a get a clean single cab
Dayummm that's a nice truck
I recommend spark plug heat socks to protect them from the heat that the headers are going to put out.
Could you have possibly used the exhaust sleeves for that section where it touches the trans cooler lines
a friend of mine used heat wrap on the header do you think this is helpful or just a waste of time?
Awesome,she sounds good.
She's good bro
How much did you bend those transmission lines to clear them off the headers
Just pried a little so they don't touch
@@lmfscrew thanks
Hey man great video ! Quick question , did the kit have all the ports for the o2 sensors ?
I have this same exhaust but mine leaks from the ears on the passenger side and from most of the clamps which idk why since they are fully tighten and idk why it’s doing that
Fudge I have a stock 2010 Chevy Silverado 1500 4.8l v8 should I do it I really want to but am a bit clueless but have some friends that will help me out
Is the rear main leaking on this truck?
Will this same set up fit my single cab 2000 chevy silverado 4x4
Did you deleted EGR Valve also where did you connect rear 02 sensors
how'd you take out the broken bolts from the head
Quick question I’m trying to order my longtube headers already but I can’t find long tubes for a 4x4 I don’t know if it matters or not I’ve always had a 2wd I’m all new on the 4wd
I don’t think there is a difference on these trucks, but I would give them a call just to verify
What did u do with the two other 02 sensor.
Long tubes into that 3” allllllllllllllllllllll the way back! Or have a shop take out that “y” pipe and run the headers some high flow cats and true dual??!!! That would be my favorite and would make Chomper live up to his plate! 😈
Damn nice interior!!
what size tips are those please respond !!
I wanna know how you got the bolts out
What did you do for your downstream 02 sensors?
Link to video about how you got the broken bolts out I can't find it
You should put a Flowmaster super 10 on chomper
How much it did cost with spark plug wires? Thank u
Can you reinstall factory cats back?
I did the same to my 2015 gmc and now it keeps running rich
Did you have this issue
Keep up the good work 👍.
I could feel the anxiety while popping those bolts loose . I’m doing the same thing soon 😐
Do true duals all the way back I had it on my cateye with long tubes sounds good as hell
What spark plugs wires did you use? Part # would be very helpful. Thanks
They are the 10" speed engineering i think part number is 26-1001
I’ve got an 05 Silverado with a full 3 inch system with the same headers and mines cammed with some other goodies if you want an idea of what it may sound like?

You notice any power loss down low with the 3 inch?
What tail lights are those?
Keep true duals and get a muffler of choice. Black widow is good or carven.
What brand was the level kit on Larry?
Now all ya need is a set of Black Widow NeighborHaters or WidowMakers and she’ll sound absolutely vicious
Can you not run duels out?
Need some Texas speed for the motor work
What wires are those ?
