you can get 2.5 custom bent piping with a muffler of your choice. You can tone it down a bit with some resonators.

Ehh I just meant engine wise but yea...2.25". Unless you plan on boosting later on maybe 2.5-3in.

evo2 is what i have,, i will never buy anything else again. i love it.. it's a beast

2.25 is best for the F22A. 2.5 is best for the H22A. 3" is best for turbo.

Many of the Japanese exhaust systems are 2.33 or something... metric. They're also often the best ones.

My favorite in terms of sound and performance would be the Apex'i World Sport. Quiet, with a nice tone when you get on the gas. Nearly silent at idle and part throttle. It has a large tip, though, and ground clearance is limited. I don't like the looks nearly as much as the sound!

i have a rs*r exhaust nice tone at idle and doesn't sound like a amped weed eater at wot. doesn't come in stainless only the tip and it is a bit pricey but i think the quality makes up for these draw backs and ground cleareance is not an issue either.

I have 2.25" tubing with a factory 95 accord ex resonator (big f'in resonator) hiflo converter with dc sports header. Now i have no rice at all....Cuz i have a factory prelude muffler from a bb4. Flows good, decent ground clearance and pretty throaty during ass whipping time.
