I think i might make a proper review on this exhaust since not many people have it.
Also some proper sound clips such as revving, launching, rolling shot etc.
Might get more people interested in this exhaust system after i make the review  |
I have one set on my 370Z 6MT. Bought it for $760 shipped from Anaheim a year ago.
Make the long story short. Very incredibly nice quality and excellent almost flawless welding spots for the price that I paid. Exhaust system fits almost perfectly . All exhaust flanges are nice and thick, therefore the sealing is perfect with no exhaust leakage at all. I am able to utilize the OEM Nissan 2.5" MLS gaskets for all of the connection flanges. The OEM MLS gaskets are superior to the asbestos gaskets that they provided.
Well, performance is noticeable from about 4800 pm up to 7700 rpm. Below that, you don't really notice that much change. I am still running full factory cats and the ECU is 100% factory except redline is raised to 7700 rpm. To my best estimate maybe 7-10 whp and some rwt increase.
Noise : No droning. But it is kind of medium loud especially above 5000rpm ( No louder than my 2014 stock Maserati Gran Tourismo V8 ). Cruising is not so bad.
Overall: Excellent. I have them exhaust all apart again because I am in the process of installing Fast intention TT system in the next few months. My goal is 500 whp. That's the reason I bought this exhaust for. It is more appropriate for forced induction more than NA.
