i have a 2004 g35 coupe with a cold air intake and magna flow exhaust. im not sure what performance headers to get. any reconmendations?

and would headers change the sound? and if so in what way?

 

try doing a search before you start creating threads.

 

HP -> $$ gains are small. I suggest a different mod.

 

Totally agree - if you have FI then maybe headers. OEM headers ain't that bad for what you have now.

 

I have stillen... I like them, only got them because I ripped out my whole exhaust system from the engine back going over a speed bump but dont think I would have gotten them if I didnt do that

 

I have DC ceramic headers. From what I remember, these headers are improved Nismo replicas, while others are copies of this one. I just prefer ceramic over stainless or polished.

But like others have stated, performance gains are minimal for what it's going to cost you.
