ok, my friend wants to know if 2.5" piping is going to be ok on his H22A, he has GReddy header by the way. He also has a short ram intake. His plans are to go all motor and he has this H22A motor in a 96 civic coupe.

 

i use 2.5" w/ jdm seawater dipped oem header

seawater= rusted to ****....i'm guessing anyway, I use a greddy evo catback which is 2.5 works great

 

I have a greddy header and a 2.5" Greddy Power Extreme exaust...it's fine for power you'll just find it a little torqueless down low....the big pipe kinda falls flat when you let of the throttle...but around 4000 roms you start to appreciate the flow it provides

I was wondering about the same thing too. I might be going turbo soon so either a step up from my 2 1/4 to a 2 1/2 or 3 inch. Gonna ride around N/A till I finish my collection of turbo parts. OT but CD8, what's your mods? I'm wondering how much whp/tq I'm putting out. I ran a 14.5@98mph with a 2.3 60' intake/exhaust.

 

2.5 for modded N/A car

3" for turbo only. Unless you have a HIGHLY modded track bitch N/A car.

What's the better size for a slightly modded H23, 2.25 or 2.5?

It will have CAI,11.1:1 comp. pistons, and 75 shot of nitrous?
