I kept the stock civic cat but had to get the exhaust extended and bent to fit. Basically my 5Zigen had to be cut and extended but that was expected. The 5Zigen Fireball Catback is 2.37 inch pipe...So kinda in the middle. You're gonna have to take it to a muffler shop to get the exhaust to fit, not a big deal anyway.
