I have been working closely with T1R (Type One Racing) so they are using my car to R&D the exhaust for the 370Z. Here's my previous post with the exhaust pics and video
My T1R Prototype exhaust !!!
My car is 2010 with approx. 5200km, bone stock with just the T1R cat-back. To be honest, I think the exhaust sounded extremely well, I will rate it better than Amuse R1000, HKS and Greddy which I have heard.
I recently got the dyno test with and with out the exhaust and here are the results.
I think the car still runs rich so with extra tuning, I guess I should make SOME more power out from it
Thanks
