Stillen vs Fast Intentions vs Invidia

^^Yours is the carbon fiber or ss? Carbon fiber is slightly louder too. Performence wise, what's the difference between the stock Nismo and FI cbe? What your butt dyno tells you? Have you ended up with a new tune?

Mine is SS. TBH, I had already done intake and HFC before I did the cat-back so the gains were hard to tell. It feels like it has slightly better throttle response, but nothing like the gains I felt from the HFCs.

I have not tuned yet. That's the next step - I have the Motordyne intake manifold, HFC, Nismo R-tune intake, and the F.I. exhaust. I'm sitting at about 290whp (100 degree day in Dallas, TX). I expect to break 300 when it's all said and done.
