I just purchased my '04 Civic HFP brand new and am looking to make an exhaust upgrade. My problem is I have no idea where to begin or really what to even look at. I know very little about the whole topic so I was wondering if anyone had any suggestions on what where to start or what to purchase. I am looking for deep sound not too loud and want quality parts.

 

wrong forum

if you want a quiet exhaust id go for rs*r, greddy, or apexi ws..

 

I got a pasesetter catback for my 96. its great I would recomend it. has a nice rich deep sound, but its not too loud.
