GOOD-WIN RACING'S APPLICATION NOTES. Folks ask us all the time to rank our Miata exhaust choices in terms of sound level. This RoadsterSport Miata exhaust and the Racing Beat single and dual tip Miata exhausts are the most quiet of the aftermarket choices. When used without the removeable baffle our RoadsterSport Miata muffler has as much as 25% more sound than the stock Miata muffler at full throttle, yet just about 10-15% more at cruise. This RoadsterSport has a little more flow than the Racing Beat Miata exhaust due to the 2.5 inch size of the tubing on this choice versus a 2.375-inch tubing on the Racing Beat (both straight-Flow internal designs). The slightly larger tubing of the RoadsterSport Miata muffler also means a slightly deeper tone and a little more burble on decel. 

LIFETIME WARRANTY, this Miata muffler is made with pride in the USA. Includes gasket and hardware needed for install.
