Completely transforms the car

Car sounds like a completely different machine now. Deep aggressive note without being annoying on the daily commute. Valve closed through the suburbs and open on the weekend. Really well made product.

My mechanic commented on the build quality

When fitting it he stopped to look at the welds and said it was one of the better aftermarket exhausts he had seen. Sounds incredible too.

Deep aggressive note

Exactly the sound profile I was after. Not raspy, just deep and mean.
