My buddy put on Corsa, no cats dynod 471rwhp

Im going to possibly go with Bellangers and see what difference it makes between the two header companies. I would say a header/exhaust /no cats package is a great bang for the buck. Nice power,great sound. Its too bad they cant come from the factory already set up like this.
