There is better exhausts out there like invider q300. It sounds porn and with the titanium tips against the blue car it suits it well. Quality is now extremely good, go to the pro speed racing web site and get a price from Troy delivered to Perth. Brett has this system on his car & open source tuned. Gorden has the butler built system with Mao tuning it with I don't know what software these days.

I put my hand on my heart and say the KW V3 are very good. Brett has these and the ride is fantastic.

These days if your able to set up the car to tune it your self through Rom Raider / open source tuning. You will learn a lot more about your car

I will let Brett explain this as his car is going through some changes in the near future.
