Hello. I have a 2000 Civic SI and I want an exhaust system for it. I already have
 

an intake and 4-1 header.? I want something that isn't to loud, good quality, but not ridiculously more than my engine really needs. It's got about 200hp.

yea heres a tip a huge exhaust actually makes ur car lose power so dont be gay n do that ur exhaust should compliment ur engine

Well, It's all personal preference, But I try to stay away from the name brands (Greddy, etc.) After the header I use A High-flow cat, 12" glasspack, and a Magnaflow muffler exiting through a 5" tip. (on a integra GSR) I think I paid $200 for all, Installed
