Exhaust System

[Eleazar]

I'm planning to turbo my H22 in the future, but I plan to get an exhaust system soon. Should I go with a 2.25 inch inlet or 3 inch inlet?

a 2.25 would probably be a bit small for a turbo H22. i would probably go for a 2.5 inch. a 3 inch would work good too so it depends what you wanna do. good luck on the turbo project.

Would putting a 3 inch exhaust system lower the performance on a non turbo?

Depends on how low your car is i scratch with 2.5". 3" and my exhaust would be draggin literally.

[Eleazar]

Nah, I meant if it would lower your total output of horsepower, etc.

[91 EX-R]

it probably would since there isnt enough back pressure.

The 3" works I know what your talking about. I am just saying if you have a lowered car might wanna try and go for a 2.5" because the 3" might cause some problems and get dinged up.

I wanted to go with skunk2 but I don't think they make 2.5". Are there any other reputable brands that make 2.5"?

[NAiL05]

2.5" what? Systems? Mine is custom so yea. 2.25 will suffice i just went bigger cuz i could. But you should find some N1 in that size. I think WS2 might have a 2.5" opening.
