How are we supposed to tell you what size piping you need if you don't tell us what engine or car you have??? Please work on your spelling and grammar to make your posts easier to read... If you have a near stock motor use 2.25". 2.5" would be overkill, I doubt you would lose any power but you probably wouldn't gain any either...

Its a 1997 Honda Civic EX i only have the V2 in it rite now so pretty much stock i just bought the car

2.25" is as big as you need to go...

how about for b16a2?
it has SRI and stock header.
I currently have 2.25" piping with 5zigen exhaust.
bad idea?

2.25" is fine for a b16 even with most bolt ons. You might gain 1hp on the very top end with bigger piping... 2.5" exhaust is only necessary on serious all motor applications for a b16. We are talking aggressive cams, intake manifold, big throttle bodies, etc... and 3" exhaust would only be for serious forced induction applications...

alrite thanks
so im just going to run it straight from headers to exhaust =]
