I am looking to make a little more power out of my VQ35de and was wondering what anyone would recommend. I have the berk intake and a custo m axel back section. I dont want to get headers because i think it will make the car sound really loud with the muffler i have. i was thinking like some ecu upgrade if there is one, or some combo of exhaust parts for about 10 hp. Any and all ideas would be greatly appreciated.
Thanks

 

Toss your muffler, get a stock muffler, get headers and enjoy the 20+ WHP and sound stock.
