I have an all motor h22 with itb's, custom cams, 14:1 compression, and an AN-R header. I was wondering if I should keep the 2.5 trend, or if I should step up to 3" from the header back

 

3"

 

I would say if you are putting out similar numbers (besides torque) to a turbocharged car, get the 3". From what you listed...get the 3". You have to have at least 230+whp...probably more.

 

thanks for the imput

 

14.1 compression .... DAMN!!!!!!!!!!!!!!!!!!!!!!

 

and to think, that car used to be turboed. good to see my old car coming to this. NA is best bishes.

 

word up.

 

3" will be loud...

Seriously, I don't think he gives a **** if it's loud. I'm sure it's not exactly an everyday driver.

 

a nice header system like SMSP or Hytech have 2.5" inch collectors. A nice flowing 2.5" inch exhaust will do just fine.

3" inch might be an overkill for an All-Motor setup, unless you go all out and plan to max it out.

 

3" exhaust will work perfectly fine with that big of a motor and that much compression, just make sure you have a good flowing header and resonate that exhaust so you don't loose too much back pressure. nice sounding setup btw! -Jason

 

2.5 is fine dogz.3'' is to goddamn much

 

so what is it then, some of you guys say overkill, some say its cool. This isnt gonna be a daily driver so im not too worried about loudness.

 

Just go with 3" and put a resonator or two in there, such as a carsound cat. You will be happy you made that decision.

does carsound make a cat that will have a 2.5" collector to attach to my header and a 3" to attach to my exhaust

 

i'm pretty sure they do. the search button is the key! -Jason

Header back? This set-up sounds like no street car I've heard of. If it is you're nuts. Custom side exit w/ 3" collector.

I thought about doin that. Its really not a street car, I just want to be able to bring it out and drive around once a month or so

 

3 inch is fine for that amount of HP IMO...
