Probably the best and most sensible advice I have been able to find. Thank you for this video and your time ! Probably saved me a couple grand on my navigator I mainly just daily drive
Oh I was just looking for this. Thank y’all
Awesome tips as usual! No pun intended :)
After my 2nd time seeing this... this was a BIG help!!! I'm keeping all 3 with limited to no raspy exhaust sound! Thanks!
Glad it helped!
I literally bought the 3" LNF exhaust with the resonator and muffler yesterday...that better be the best :)
Looks like you are GTG.
@@benwp4179 yes sir
I just got a 3” header and downpipe to a 2.5 straight pipe 🥴
I have a shorty header w/catless 3inch to 2.5 to shorty resonator to 2.5 back. I used to have a zzp muffler but I blow them out in about a year and a half with all the fossil popping it does. I went with a fx flowmaster....and it sounds waaaaay to loud.
The shorty warped and cracked the primaries, I welded it up but I still need to go back and find the leak. I will probably get another shorty header and cut the flange so it doesn't warp again and ride that for another 3 years lol. ......maybe another muffler from you as well, they have a great sound.
Lsj.
I love it my guys zzp keep up the work and I love the video and I wish you guys make a exhaust for chevy trax ls sport 2018 be good 💯💯💯💯💯💯💯
Im still tryna quiet my 3800 just a lil more.....thinking about that 3" resonator from ZZP .....I think it 24" or 30" long but is should work👍
Cheers man. This helped me a bit in my exhaust build for my Harley Night Rod Special. 1250cc with 126 rwhp ish, 86 ft lbs peak torque at 7k rpm. Redline at 9k. Went with 2" headers stepping into 2,125" that then merge into a collector with 2.5" outlet into a 17" long muffler with perforated core and reversion cones. Seems reasonable?
For me with out resanator and muffler sounds great its all depend your tasted
Knowing the original stock diameter of my 2002 GTP cat back exhaust would be a great help in determining which changes would compliment the engine modifications I’ve done so far.
I already have a Random Technology down pipe, high flow cat and U-bend replacement. Could I please get an expert reply from ZZP ?
Thanks 🏁.
It currently has oem sized 1-3/4 but I would like to know if the 2.25 inch sized exhaust, be good with the N/A 2.2L Cobalt, from just after the cat to the muffler, without negative effects and without needing tune ?
Thanks in advance.
I'm doing an na build to super charge on my l36 3800 down the road. Love these tips
Good luck!
what piping u recommend for a 2017 honda accord sport 2.4L...with borla muffler? but not too quit and not too loud ...thanks
@@mrgigady6475 honestly it depends what you're after personally I don't think any 4-cylinder sounds good no matter what type you put on. I don't like the fart can sound tho so I'm bias. However unless you're running 10 + pounds of boost the stock system you got will probably be just fine with something like a thrush or cherry bomb. Dont need to go crazy i prefer the thrush to most others for sound tho or dynamax.
@@stevejenkins9984 thanks
@@mrgigady6475 look into invidia exhausts. They're very popular with hondas and sound amazing. 4-cyl, 6-cyl, regardless.
Would you reccomend a 2.5” for a b18c civic that’s turbo? Looking to break 300hp but obviously it has a pretty small displacement, kinda feel like I’m stuck in the middle looking at exhausts. Most forums say shoot for the 3” or you’ll choke the turbo, but I would prefer not to make my cul de sac of old suburban neighbours mad at me😬
I have a 2017 Honda Civic 1.5 L turbo, I can’t decide wether to get the 3 inch or 2.5, I do however want to get a high flow cat downpipe, but to go with that none of the big name exhaust systems sound good to me, what do you think would sound the best
I have a Nissan 350z 2008 VQ35HR with stock header manifold, Kinetix hfcs with the o2 extender bung, and a Top Speed Pro1 dual exhaust. I was thinking about installing Tomei headers or maybe Z1 headers on my car and was wondering whether I would get a check engine light or not if I do?
Dang thanks for the info. I have a cruze that I am doing a mid build. And good to know to keep it 2.5 exhaust.
so much info in such a short video.
Will a smaller exhaust tip say from 2.5 inch down to 1.5 inch restrict the sound and power?
What are your views on thr nissan z coming with small pipes? And doing a step up ? So most of my system is 2" theres a resonator and after the axle back is 2.5" no exhaust ....
I've been wondering how much we can actually alter the specific sound of a car's exhaust with various alterations. Like, I got a Focus ST to be one of my daily driver but... It's a bit boring and far too quiet for my liking.
I'd like to compare the difference (if any exist,) between running a 2.5" pipe after my rear muffler (about 2' long) and. 3" pipe at that location. Not a concern with all is wlñd
If you just want noise its the types of mufflers that make the difference not the pipe diameter.
Hi bro plz help me out. I’m wondering about my V6 challenger I wanna install 3inch X pipe with 2.5 fox mufflers. What do you think about it? Plz reply to me
I have a mazda 3 with stock lines 1.5 what do you recommend to sound the best?
Hello mate ihave a plan to replace my down pipe and mid pipe in 2.8 litre engine what inch should i take. 2.5 inch or 3 inch? Thanks.
I have a mercedes c250 and I want to upgrade my exhaust system. It's a 4 cylinder turbocharged and I've done some mods for now and want to keep adding more power. What set up would you recommend?
What about a 2017 q50 3.0t awd? Right now I'm looking to go 2.5
Do you have the special order a 3" for A350Z with twin turbos
I Have a 1.8 single cam engine and what I did is I put a 2.5 inch exhaust system and 2 inch header, no cat converter. Is that ok?
RyanDeez and ZZDeez here guys.
Hey man ,I've gota ford falcon g6 4 cylinder turbo /ford FG ecoboost and I have no idea what exhaust to get ,can you help me out please ? Thanks 👍
I have a magnaflow catback with a 2.25 inch diameter pipe with a 3 inch dual exit
Waiting for the Ecotec LSJ long tube headers to be back in stock 😁
I have one for sale basically brand new
I’ve seen 600 hp V8 running 2.5” exhaust. Why the need for 3” on a 300 hp 4 cyl? I have a sonic and am not bashing. I’m just wanting to know. I’m currently running 2.5” and if I need to increase for more gains in the future I will.
600 hp NA? NA or SC engines can "push" the exhaust out with the natural pumping action of a engine. A turbo engine you now have the exhaust turbine using most of the energy to spin and make boost in the compressor side of the turbo leaving less energy to push the gasses out of the rest of the exhaust system so you step up in size to reduce back pressure after the turbo.
What does that red car have as a exhaust, sounds good?
What the best for e55 amg 3 inch or 2.5
Hello there, would it be okay if i use 2.5 inch for the pipe but then for the muffler part i use 3inch? I’m having just a lower power car around 150hp. And would you recommend if i wanna do valvetronic exhaust system? Thankyou for your time, looking forward to get a reply from you soon!
Hi Ahmad, Unless you plan on adding 300+ hp to your vehicle, we recommend keeping the exhaust system at 2.5 inches all the way back.
thanks for talking sense into some of these embarrassing folk out there.
How you fight drone in 3" exhaust, turbo car 500hp
2.5 is necessary for N.A. cars. 3+ is good for power added exhaust
Have a c63 amg 6.3l
520 hp
And 440 tq
Do you think I should do 3 in just tuned and highflow cats
Yes I would personally
Opinions on a ls1 410rwhp
2.5 vs 3.0 anything think it's worth upgrading to 3 inch?
Also has 125hp nitrous so with that runs just over 500rwhp
Did you upgrade?
I’ve got a 2013 scion tc the factory exhaust is 2” I plan on getting 2.5” exhaust (Megan racing drift spec). After watching this video I now have a better understanding of exhaust sizes but I just wanna make sure that it’s ok to get that exhaust does anyone know for sure?
Yes, 2.5" will be perfect for your vehicle.
What you recommend I go with on a 2002 BMW 745i 7series????
Make a dual system
Go with magnapacks 14419 and remove the kanister mufflers with x or h pipe...
So on the 3800 with the XPZ cam, 3.0 pulley, 42.5# injectors, ebay headers and 3" catless dp , on 91 octane. I was thinking 3" since ive got a 3" dp, what size catback would you recommend? I have no idea what to expect power wise out of this build. Maybe 300hp?
With that 3” pulley you really should be using 93 octane fuel for the optimum results. I think dyno testing the two different fuel grades would show a significant difference.
@@danielwilson6665 we dont have 93 in Oklahoma. We have 87, 89, & 91. At least not at any of the gas stations around me anyways. The car is now getting a new engine with a brand new xpz cam, fsic, 2.9 pulley on e85. 80# injectors. ZZP front and rear plogs. ZZP 3" catless dp. Its gonna be sick tho when its done.
@@PontiacsGarage … That new engine combination should be very potent for sure. Using e85 should also satisfy your octane requirements. I hope everything goes well for you 👍.
@@danielwilson6665 hell yeah thanks man. Me too. I appreciate the feedback
my 2005 BMW 330CI has a stock 2.25 DUAL piping exhaust. Would a Single 2.5 inch pipe be sufficient? Car only has 225hp. thanks
Late response but yes I have that setup on my 2002 330ci it sounds nice and you won’t lose power but also won’t gain any
New sub.
Welcome!
Quien fabrica estos escapes para 3800
I like to compare exhaust size to how big the opening of your mouth is for when you exhale for exercise. For example, if you bench, you gotta find the sweet spot so you can give proper power while exhaling or else you’ll be too short of breath or you start suffocating bc your not properly breathing well enough
Scientific data such as this should also include variables such as how smoking skews the difference in test results.
My car makes 210hp at the crank, by the end of it, id like to be at 210whp. 2.5" good enough or will 3" help me get there?
2.5" will be plenty for that power level.
How about a 200hp engine.what size do you propose.2 in?
Yep! A 2-inch exhaust would work fine for anything under 300hp.
What about a 2.5 inch ?
Am looking into doing a 2.5 exhaust for my cobalt
straight piping my honda civic les goo 3inch pipe
I have a 2.5 DNA Motoring Cat-Back Exhaust System for my 09 Cobalt LT sedan but Im still lookin to see what downpipe would fit best for my car
Just sick of up And go zzp. I couldn't have been happier when I finally got mine.
I have a 5.0 genesis
how much did it cost to put that hood vent on that ats?
Get the ATS V hood and slap it on... it varies who you get it from if it's just ATS V styled or OEM ATS V Carbon Fiber Hood. ATS V Styled aluminum is probably $1200, carbon fiber styled is probably $1800, and OEM I'd imagine is most expensive and I'd guess $2500.
Obviously if you get the carbon fiber option on your non V ATS you can't use the OEM arms. You will need to buy and install a different hood lock & the arms, if I'm not mistaken... there really is no need for the hood extractor on the 4 cylinder turbo ATS since heat is not a issue at any level, unless you put a much bigger turbo in. I can't speak on that heat issue with a larger turbo, as I never went that far in my non V ATS, but was stage 2 ZZP+ making over 500RWHP and running 11s without any E85 in & on just a 91 tune.
It would just be for looks really and kind of a waste, especially if your carbon fiber hood extractor chips/ fades/ or breaks... your out almost a grand on the OEM and like 500 for a knock off & that is without the labor if you pay someone to install.
i got bought your 3in cat back for my new sonic because yes the straight piped 4banger is annoying as hell and i don't care about the loss of low end power
Can you show about calculations part
Calculations on engine to pipe size is very hard since many variables to consider. Number of pistons, size of engine, timing and lastly is length of exhaust pipe. But we do know that smaller diameter pipe has a faster flow for a given volume of air/fluid compared to a bigger diameter pipe. Smaller pipes = Faster flow means better scavenging at lower RPMs. Meaning the torque and power are achieved earlier in the powerband which is perfect if you just want an upgrade in drivability and increased mileage. On the otherhand bigger pipes will allow your engine to breathe better at high RPMs making increasing power but your torque and hp are moved up on the powerband.
Is buying a cobalt 2005 for 3000 good? 130000 miles
Ok if its solid but there not really desired rare expensive cars. For 3k is should be solid minor to no leaks in the heartbeat
2.5" is great for sound, but zero power gain. If you want sound AND increased hp, get the 3" and find a shop that knows how to tune or it will drone.
Does having too large a pipe have any negative impacts on the engine I.e. back pressure?
No. It only reduce the torque.
I have a 04 monte carlo ls and I'm really trying to figure out the difference between the zzp and magnaflow as far as performance and why the magnaflow cost so much more??
While ours is cheaper than the Magnaflow, it's also higher in quality. Magnaflow systems are mig welded and do not have chambered mufflers or resonator which means they are really loud.
@@ZZPerformanceChannel really loud is what i’m chasing 😭
@@xytics5519 … Really loud doesn’t typically mean maximum power. If your goal is getting noticed, then go for it 👍.
What about Chevy 350 TBI?
Same. 1 5/8" primary headers w/2.5" collector to a 2.5" y pipe that joins to 3" all the way back. Great setup so far. I might size up the y pipe to 3" as I reach the 350-400hp range.
@@adaml6458 … A Y-pipe with a single exhaust pipe on a V-8 engine won’t do anything to improve performance.
Consider getting a H-pipe or a X-pipe for a true dual exhaust system of 2.5”all the way back. It will sound and perform much better than a single pipe.
I have a question. I have an '09 Silverado with the 5.3L; it is a true dual with 2.5" exhaust all the way back with a pair of flowmaster 40 series. I would like to put a pair of flowmaster outlaws in their place with 3" inlet and outlet and have 4" x 18" tips. My question is: Would it be better to run 2.5" or 3" pipes with my motor?
How about for a 2.4liter turbo diesel engine with 200 whp? 2.5 vs 3in?
Mukhang 2.5 inch na sagot nya dyan broski
Anything less than 300 daw, 2.5 inch
Ayaw ni boss syd yan
V6 engine s akin 2.5"
nadudugas kasi dyno kaya medyo di ako paniwala na 3in talaga nga rin boss hehe@@JTTJ000
So does the 3 inch is better
Checking out the results again is probably better.

Zzp you hardly ever answer emails.
What’s size for a g35 coupe n\A
Since most g35's make under 350 hp, a 2.5 inch exhaust will work just fine.
@@ZZPerformanceChannel thank you for the reply. The hp number you guys go off of is to the crank or to the wheel ?
@@g35tho11 Wheel
@@ZZPerformanceChannel can’t find a y pipe with a 2.5 diameter in and out ..
99% of the time your exhaust is too big. The guys at the exhaust shop dont have a clue what they are doing. The best perforrming exhaust is headers with small primaries and a small size exhaust. On a naturally aspirated nothing over 2.5 inch and in most cases thats way too big
You are nuts watch engine masters if you are running a v8 2.5 inch kills 40 or 50 hp.

أنت فقط تحتاج لاختيار المقاس المناسب لسيارتك .
الجزء الأول : 2.5 إنش الخيار الأمثل لسيارات الأقل من 300hp .
يقول الشخص الذي في المقطع ، بأنه عند قيامك بتعديلات على السيارة لست بحاجة إلى 3 إنش ؛ لأنه سيضعف أداء السيارة و صوت مزعج ، و ستلاحظ ضعف واضح في الأداء أثناء سير السيارة .
الجزء الثاني : 3 إنش الخيار الأمثل لسيارات الأكثر من 300hp .
يقول الشخص الذي في المقطع ، بأنه عند قيامك بتعديلات على السيارة و بدأت تزيد عن 300hp الأفضل الانتقال إلى 3 إنش ، هنا بيكون في زيادة في أداء أكثر .
ملاحظة من الشخص ، أصحاب محركات lsj السيارة لما تكون straight pip (يعني ما فيه دبات تلوث ما فيه شيء ، من المكينة للشارع)بيكون صوتها ليس جميل ، الأفضل تركب لها ثلاث أشياء (resonator) و (muffler) و (high flow cat ) وشكرًا
أتمنى أن كل شيء قلته صح و أي ملاحظة ما انتبهت لها أو شيء غلط صحح لي بتعليق (غير كذا لا تعلق) (أستبدل كلمة شكرًا بلايك(👍) فقط ، عشان ما تكثر الرسائل ع الفاضي) وشكرًا لحسن قراءتك
