RoadsterSport 3 Polished Stainless Steel Miata Exhaust Muffler

This Miata exhaust muffler has been a customer top choice for many years. Deep mellow tones flow from our favorite Miata exhaust muffler choice...and 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! YES, fits manual and automatic transmission.

Built in solid 304 stainless steel and completely polished to a mirror finish, this high quality Miata exhaust is our 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). Weight is just 18 pounds (lighter than factory).

For those that want even more sound add our highflow Miata midpipe for more flow and another 10% more sound. This new version of our 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.

And, you always have the option of our packed baffles which are sold here separately. Our use of special high density packing materials and a higher perforation rate in the straight through core than most Miata exhaust makers allows us to save more weight over the factory Miata muffler than other choices while still giving you the most mellow sound. For even more flow and sound check out the optional Miata performance midpipe by searching "midpipe" or see it in the list of choices on our Miata exhaust page (paricularly good choice for turbo and full race users).

INSTALLATION:
Install is awfully simple. Disconnect the two nuts/bolts connecting muffler to midpipe. Use dish soap on old stock muffler rubber hangers to get them to slide off. Ideally have exhaust hanger removal wrench handy to make getting the rubber hangers off even easier (even Home Depot now sells them for about 20 bucks). Revers those steps to install the new muffler. Tighten nuts to 30 ft/lbs

Brian'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. YES, includes gasket and hardware needed for install.
