Exhaust - RoadsterSport 3

Deep mellow tones flow from Good-win Racing's Miata exhaust muffler of choice.  This Miata exhaust muffler is the ONLY 99-05 Miata exhaust with an optional highflow midpipe with built in converter and resonator (sold separately) AND adjustable sound level!

Built in solid 304 stainless steel and completely polished to a mirror finish, this high quality Miata exhaust is the only choice that incorporates a baffle insert that gives YOU some control over the final sound level (baffle in is only about 15% more sound than stock, baffle out is about 25% more sound than stock...so you always have a choice for those longer trips).

For those that want even more sound add our highflow Miata midpipe for more flow and another 10% more sound. This new version of Good-win's best selling Miata exhaust has both baffle included and a double walled tip for years of lasting good looks while giving you control over whether the final sound level.   Also, you always have the option of Good-win's packed baffles which are sold here separately.

Good-win's use of special high density packing materials and a higher perforation rate in the straight through core than most Miata exhaust makers allows them to save more weight over the factory Miata muffler than other choices while still giving you the most mellow sound. The stock Miata muffler is 25 pounds.  Good-win's RoadsterSport 3 Miata muffler is just 12.4 pounds!

With an ear pleasing exhaust note, great price and easy installation, this Miata exhaust is a great beginning for Miata performance modifications.

For even more flow and sound check out the optional Miata performance midpipe by searching "midpipe," or see it in the list of related items below.  Of course, it's also listed in the exhaust category section of our website.  The Roadstersport 3 and midpipe combination are a paricularly good choice for turbo and full race users.

Good-win's Application Notes:

"Folks ask us all the time to rank our Miata exhaust choices in terms of sound level. This RoadsterSport Miata 3 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 3 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 3 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.

This Miata muffler is made with pride in the USA."
