Nissan 370Z Forum - View Single Post - V6 X-pipe VS H-pipe flow test

I have the GReddy Evolution GT catback exhaust with Fast Intentions high flow cats and it is loud but once it's warmed up it's not too bad. It's definitely a cleaner and overall better sound than if I had test pipes. Also, that catback keeps the OEM exhaust tone while enhancing it.

It flows pretty good mid-range to redline. I found that I lost a little bit power, mostly torque, below 3500 rpm.

The sound is very nice and my friend who has a Magnaflow on his G37 likes it a lot

I read somewhere that the Nismo OEM exhaust was made by GReddy but don't quote me on that.
