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.

Transforms the driving experience

Every drive is more enjoyable now. Sounds amazing on full throttle and totally liveable for commuting on the closed setting.

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.
