Love it
Matt smith | June 7th, 2023
I have this paired with a rv6 high flow cat and downpipe, fuel efficiency increased dramatically. Sound is low and throaty, not obnoxious. Love it its perfect.
Good product, lousy shipping choice
Andrew Martone | June 25th, 2020
Product came as described, no blemishes or damage. Bolted up really easily and nicely since I already had an invidia N1 exhaust on the car. Love how much it quieted the car down for daily driving and driving the kids around. My only complaint is the UPS shipping. Would have much preferred fedex as they deliver on saturdays and sundays. The exhaust sat at the UPS facility all weekend and i had to install during a weeknight after work rather then the previous weekend.
Big time quality, great sound

I would recommend this exhaust and KSP for all car needs! Thumbs up
