This MX5 Exhaust was designed for RACING...it weighs just 3kg! In particular, this MX5 muffler was designed for the autocross and track MX5 drivers. It may also appeal to some MX5 owners who want a SIMPLE AND PROPER SINGLE SIDED MX5 EXHAUST. Let's face facts, dual exhausts on a straight four cylinder MX5 is a ridiculous waste of weight. Mazda talks about gram strategy in the development of this new MX5 but they wasted a lot of weight on duals that provide no performance benefit and lots of extra weight.

Yes, this RACE exhaust is on the LOUD side of our choices but what the racers need to know is that max recorded db usually 85-88 db at 15 meters....well within all track and autocross limits and low enough that many will run this MX5 exhaust on their daily driver and love it.

Just 3kg means this MX5 muffler is 9kg less than the stock MX5 muffler! How do we do it? By using a higher than normal perforation rate on the straight through super high density core to get maximum sound suppression with absolutely minimal weight. This 3kg MX5 exhaust compares with 8.5kg for our RoadsterSport MX5 Duals and over 11kg for the factory exhaust.

Does NOT include baffle insert like the RoadsterSport MX5 Duals, but we offer separate special optional baffle insert. SHIPPING NOTE...ships factory direct to you, in stock now. 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.

BRIAN'S APPLICATION NOTES: Besides making the racers happy, this is great choice for the street use MX5 owner who will be changing ONLY the muffler....because on an otherwise stock MX5 this is actually relatively mild when cruising, delivering a classic sports car bark when you stick your foot in it...tons of fun, better performance, and much lower weight.

 

Nonetheless, this choice is not for the faint of heart. The most common question we get on this one is: "will it be too loud" and we cannot answer that one for you because the "right" sound level is a matter of entirely subjective personal preference. One observation we have made is that customers under age 30 seem to consistently feel it is just right, not too loud.

INSTALL NOTES:

Read full installation hints and notes in our forum Installation Instruction Section HERE! The secret is LUBE your hangers well with dishsoap so you can get flanges aligned properly, and torque the supplied hardware to NO MORE THAN 25-30 ft/lbs (using more torque will actually result in LESS seal because you will pucker the flange out at the middle).

And here is what you get if you go full Good-Win Racing RoadsterSport MAX Power Header, RoadsterSport Midpipe (version with converter and resonator), and RoadsterSport Race....the header REALLY opens things up, this combo not for the faint of heart!
