Our favorite Miata exhaust choice together with our favorite Miata midpipe choice...and the ONLY 99-05 Miata exhaust with adjustable sound level!
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 5 to 10% more sound than stock, baffle out is about 10-15% more sound than stock...so you always have a choice for those longer trips). For those that want even more sound, this combo with our highflow Miata midpipe adds more flow and another 10% more sound (note midpipe does NOT fit MAZDASPEED Miata).
This new version of the RoadsterSport Miata muffler has both baffle included and a double walled tip for years of lasting good looks while giving you control over over the final sound level. And, you always have the option of our packed baffle insert which is sold here separately. Despite the relatively conservative sound, our use of special high density packing materials and a higher perforation rate in the straight through core than most exhaust makers allows us to save more weight over the factory Miata muffler than other choices while still giving you the most mellow sound.
Stock Miata muffler is 25 pounds....our RoadsterSport3 Miata exhaust is just 12.4 pounds, and the RoadsterSport Miata Midpipe saves another few pounds off the stock Miata midpipe. With an ear pleasing exhaust note, great price and easy installation this Miata exhaust and Miata midpipe combination is a great package to support additional Miata performance modifications including turbos and superchargers.
INSTALLATION: See Forum Installation Section! The slip joint in the middle of this item is your friend, lube it up and adjust length and clocking position as needed (if you ignore this note and shove both parts fully together you will make it all too short and that will cause contact with the differential....and you can fix that by adding some length at the slip joint.). .
