I purchased a 2010 G37s with a OEM sport exhaust. i was wondering if it will be worthing to change it to aftermarket exhaust. does the sport exhaust add ANY hp comparing it to the stock exhaust? i was thinking changing it to HKS, ARK or H.I

 

a bit, not a whole lot, look into FI

 

id definitly go aftermarket. when i first got my G i loved the sound and knew I wouldnt go aftermarket. After 3 months i bought a Tanabe system. Sounds so exotic i love it!

 

fast intentions for sure!!!!
i love mine so much!!

i think i posted this comment a thousand times lol

 

A few days ago, I pulled the trigger on a Stillen exhaust. From the videos I've seen, it sounds pretty nice, but keeps a bit of the OEM look. They're also running the FREE GEN 3 INTAKE promotion, which sweetened the deal. Don't look for a whole lotta horses, but a decent gain, and the growl of the VQ.

 

I have a Stillen cat-back for sale...PM me if interested. Barely 1k on them. Infiniti approved and endorsed!
