you guys think putting an apex n1 exhaust on my turbo gsr will make more high end power? is it a turbo exhaust? well my friend gave me his apex n1 exhaust and i was thinking about putting it on my gsr and do 2.5 inch pipping. will that increase my high end hp with my already gutted gsr cat converter? oh yeah, anyone know if the apex n1 exhaust is loud? or deep toned? anyone with input hit me back..thanks!

I had the apex n1 catback and changed to a custom 3" with a 3" N1. Made a world of difference in hp and back pressure relief. I would get a 3" exhaust.

N-1 on a Turbo yields a deep mellow sound...not loud at all.. It took me while to get use to but I like it a lot now. not abnoxious at all like a 3 incher could be.

As far as power, you will compromise som high end power, but you will have plent of lowend and mid-range torque. If you want your car to be kinda stealthy and have good power, the N-1 is a nice choice...if you want big power all down the power band, and don't mind the noise, then do 3 inch.

cool thanks for the info, guess i'll go get pipping for the n1 and throw it on, might as well use it if its for free... haha

Sell it if it's free and buy somehting bigger, if you dont go three inch atleast get a 2.5, greddy also makes the PEII which is 2.75 inches and looks very similar to n1 style.

If you want N1 just go with custom 3'' piping from KTELLER and get a universal turbo N1 muffler, those are my plans at least...
