Nice comparison
I doubt that guy will ever be sold because, who would build a 2.5" exhaust then build another 3"? The person that just did a ton more mods. Either way lets say you didn't have a good comparison because say you have a much more effecient CAT now or the Vibrant has much less restriction. Who really cares. I mean if the 3" dosen't hurt it then all it does is add options for the future(turbo?)

I'm interested because it sounds like its pretty quiet. Would you mind saying the length of your resonator, and maybe the dimensions of your Vibrant?

Also it looks like I'll be getting a cold air intake sometime.

damn! thats quite the exhaust. i was planning on 3" for my turbo build.. i cant sell that damn exhaust for my life.. where are all the people who want big exhausts? step up to the plate and grab my kteller 3" stainless lol

EG8 · 01-31-2008, 08:22 PM

I do believe i have an 18" resonator and the vibrant itself is a 3" in and 3" out but the dimensions i do not know. You can go to the performance section of our sponsors and find the information there. I have the Single Tip Muffler

M@ · 01-31-2008, 11:07 PM

And you say that you can't hear it at highway speeds? Only the intake? Or was that someone else?

JDogg · 02-01-2008, 03:52 AM

i have been telling people for a long time that 3 inch is the way to go, but nooooo one wants to hear it, ever...

Amen to that.

Most don't realize back pressure builds as rpms increase. This increases engine pumping losses. For your exhaust, you want the lowest back pressure possible over the entire rpm range to recover those losses.

its much much quieter at highway speeds then my skunk2. When you get on it you hear more intake then exhaust but i had a buddy of mine drive it so i could listen, and it sounded great to me.

now get some more shit done and come on over to tallahassee

Shadowz7429 · 02-02-2008, 05:35 PM

wish this was made before i bought my system lol

hpi247 · 02-02-2008, 05:44 PM

sound/video clip?

oldskool teggy · 02-02-2008, 06:38 PM

Some more ammo to support the "bigger is better" theory in regards to exhaust;
IME (in my experience) 2.5 has proven to inhibit flow on my 1.8 LSV as well. So I would buy a 3" on anything 1.8 or bigger

here is the foundation for my statement, on my setup... analyze against yours accordingly. This may or may not help you.

this is toda header uncorked vs. 2.5" exhaust and straight pipe. Same motor, same dyno, same tuner
Blue line is 2.5" exhaust system w/ 2.5" test pipe
Yellow line is open header
Green line is 2.25 exhaust w/ 2.5 Catalytic

Notice how the power is quite even until 7k, then it falls off.

I'll add that I just built my 2.5" exhaust, but I wish I had gone to 3"

Just bought a nitrous kit, got a killer deal on it i could not pass up, not the greatest kit but worth playing with nonetheless.

Will try to get video clip of the exhaust

EG8 · 02-28-2008, 03:31 PM

I got back on the dyno today and final numbers were 187.5/148.8 for torque, so tuned, it was a 12whp and 7lb-ft of torque difference from start to finish.

oldskool teggy · 02-28-2008, 04:40 PM

what did you change?

EG8 · 02-28-2008, 04:59 PM

nothing from the 180whp dyno except tuning. i did 175 tuned on old exhaust, 180 untuned with 3" and 187 tuned 3"

EG8 · 02-29-2008, 03:40 PM

Updated with Tuned Dyno Graphs!

codeh22a4 · 03-01-2008, 01:37 PM

wow,well i have a jdm kl-ze 2.5 v6 engine and everybody goes for 2.5 exhaust kuz they say 3' is overkill but its a damn V6 2.5 ENGINE how can it be overkill?!

oldskool teggy · 03-22-2008, 02:02 PM

i shoulda gone 3" too

people will still say 3" is way too big, just like the H22 is way too heavy

I'd like to hear that exhaust setup. I'm curious to hear what your interpretation of "quiet" is

BTW - What was the A/F ratio? and what should it be at for a basic I/H/E H22 motor?

ketchup · 07-20-2008, 12:03 PM

yeah, too loud for street IMO. I don't like it when people stare. I'm going to assume no cat, what about res (lenght)?

98vtec · 07-20-2008, 12:15 PM

i have a magnaflow cat and a 18" resonator from vibrant.

its really not that loud.

00MRSi · 07-21-2008, 08:40 AM

Nice..

I'm using 3inch KTeller piping with 3inch vibrant muffler and 2 SMSP resonators. Think they are 12 inch each.. No cat.. See what happens..

Shadowz7429 · 07-21-2008, 10:42 AM

have you driven your car with the setup?
