A performance RX8 exhaust adds both horsepower and sound to your Mazda RX8 by allowing your RX8 motor to breath easier. Every horsepower that your Mazda RX8 motor does not have to expend to push exhaust gasses down the tail pipe can be used to turn your wheels instead. Note that some of these RX8 exhaust choices are very LOUD and should be considered for track use only. Our favorite RX8 Exhausts for street use are the Racing Beat Dual RX8 Exhaust and the Racing Beat Dual RX8 Exhaust with Twin Tips on each side. If you have questions about which RX8 Exhaust choice fits best into your plans, feel free to contact us.
Roadstersport II was a great purchase, easy install, and sounds great.
I think that Brian Goodwin is the perfect example of what is good about the aftermarket industry. He is one of the few vendors that actually cares about his customers. He is the example that all companies should be trying to emulate when it comes to customer service. Not to mention his ingenuity and desire to improve on what is already a great car. I have never had a "bad" experience with Good-win-racing. Well, except for the constant temptation to SPEND MORE MONEY.
