This MX5 Muffler was designed for both RACING...and STREET. Our original RoadsterSport "RACE" MX5 Muffler is an amazing 3kg and designed for the autocross and track MX5 drivers who need to meet sound limits in the low 90 DB range with absolute minimal weight. Our 3kg Race has also been a big seller with our younger MX5 owners seeking to make a statement and have some fun with their street use. However, many asked us to make another single more focused for the street users... a fun single MX5 Muffler that is more subtle than our 3kg Race wonder...but almost as light. That turned into a tough challenge and after many prototypes you see the production version here.
Why a single for street users? Let's face facts, dual exhausts on a straight four cylinder MX5 is a ridiculous waste of weight for the serious sports car enthusiast (Mazda talks about gram strategy in the development of this MX5 but they wasted a lot of weight on duals that provide no performance benefit over singles YET lots of extra weight).
Just 5.5kg means this MX5 muffler is 7kg less than the stock MX5 muffler! How do we do it? For this design we started with our 3kg Race and added more diameter filled with sound suppression materials and we separated the sound suppression chamber into THREE internally baffled chambers for sound wave attenuation in what is still a highflow design. By using a higher than normal perforation rate on the super high density core, WITH three internally baffled sections, we get absolutely minimal weight and sound for a 5.5kg single.
This 5.5kg MX5 exhaust compares with almost 9kg for our RoadsterSport II Duals and over 11.5kg for the factory exhaust. Does NOT include baffle insert like the RoadsterSport MX5 Duals, but we offer separate special optional baffle insert. Final is All POLISHED stainless steel construction and a 2 year warranty. Uses stock hangers and connects to either our midpipe or the stock midpipe. Proudly made in the USA. Includes mounting gasket and hardware.
Made in the USA with a LIFETIME WARRANTY. Fits all 2005 and newer MX5’s with manual or automatic transmission, soft top or retractable hardtop.
Installation of this MX5 exhaust is SUPER EASY…just two bolts! You don’t even need to jack up the car, this installation can be done in your driveway! This MX5 exhaust is guaranteed for as long as you own your MX5.
