This MX5 Exhaust was designed for RACING. In particular, this muffler was designed for the autocross and track MX5 Miata drivers. It may also appeal to some MX5 Miata owners who want a SIMPLE AND PROPER SINGLE SIDED MIATA EXHAUST. Let's face facts, dual exhausts on a straight four cylinder Miata is a ridiculous waste of weight. Mazda talks about gram strategy in the development of this new Miata but they wasted a lot of weight on duals that provide no performance benefit and lots of extra weight.
BRIAN'S APPLICATION NOTES: Besides making the racers happy, this is great choice for the street use Miata owner who will be changing ONLY the muffler....because on an otherwise stock Miata 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.
Tarnish Alert! This choice is about function above all else, and one downside of making it minimum weight is no fake double walled tip to keep the outside metal looking pretty, you must expect with this single walled choice that it will tarnish with heat because that's what happens to single walled stainless steel. If that will bother you, get any of our other choices that has a double walled tip and weighs more as a result.
Yes, this RACE exhaust is on the LOUD side of our choices with just a 4" diameter and 9" long muffler. But what the racers need to know is that max recorded db usually 85-88 db at 50 feet.... 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 8 pounds means this Miata muffler is almost 20 pounds less than the stock Miata 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 seven pound Miata exhaust compares with 19 pounds for our RoadsterSport Miata Duals and over 26 pounds for the factory exhaust.
Does NOT include baffle insert like the RoadsterSport Miata 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 LIFETIME warranty. Uses stock hangers and connects to either our midpipe or the stock midpipe. Proudly made in the USA.

Nonetheless, this choice is not for the faint of heart, and not recommended for owners with automatic transmission. 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.
SORRY, this small item ends up in comparatively large box that is too big for the postal size limits for shipping to New Zealand and Australia.
INSTALL NOTES
Read full installation hints and notes in our forum Installation Instruction Section! --- CLICK HERE TO READ MORE. 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!
