I need a new new header and exhaust combo. which will give me a good sound with nice performance. i have a 2000 civic si

 

I have the apex N1 exhaust i love the way it sounds, not too loud in my opinion. just got a dc sport 4-1 header so we'll see how that sounds. oh i have a b18c too..
also have a high flow cat.

 

I have a crappy DC 4-2-1 header with a 2.0" collector and a 2.5" apexi n1 exhaust on a gsr. It sounds nice but Im on an open header so its loud as **** right now.

 

if you want something a little quieter but with good tone check the apex'i world sport exhausts... i had an n1 on my old civic but i got a ws2 for this one and its great, not as loud but i love the sound it makes

 

WS2 exhausts are nice i agree smaller tip too. not as "ricey"
