I have a bit of a problem, I had purchased an exhaust (Apexi N1, high-flow cat and a dc-sports 4-1 header)for my 2000 Civic Si. I had local tuner shop, where I got the parts from, install it, they said there's nothing wrong with it, but its really buzzy and nasty. I shelled out a lot of money to avoid it sounding like a wal-mart special exhaust but it still does. and im pissed. I should have known the N1 was loud. but I didn't expect it to be a weed-wacker exhaust. so if you guys could let me know what are some really good sounding it would help a lot. thanks

 

buy a resonator and put it in the exhaust.
