Ok so I have a set of test pipes on a stock exhaust minus the muffler I am planning on doing a full exhaust but I am wondering which headers are the best bang for the buck any recommendations would be greatly appreciated

 

OEM are great unless you boost.

 

Im in the same boat as you Im looking at DC sport race headers. they have the best welds I have read. I just got a ARK duel catback. going to get it tuned and the REVup all at the same time

 

Yeah I'm still debating on my exhaust I was gonna start f on the front and go back when I got my test pipes it was for my wideband so I was like ok let's do headers too now. I seen the D.C. Sports I was looking at Borla too I'm eventually going to be FI via supercharger so basically wanting to go the right route the first time

 

You do realize the revup is a motor right?

 

I mean UpRev tune lol

 

Exhaust systems for our G35s, best advice is to spend your $$ on a quality cat back exhaust system like Magnflow or HKS! Followed by ART pipes or HFCs since most of the restriction is in those OE cats. Once you have a exhaust like these, the gains you'd receive adding headers isn't worth the minute less than 5 WHP gains!

Get this too if you are doing headers. G35 & M35 5/16″ Copper Iso Thermal plenum spacer Im going to get this thanks to Blue
