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 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. Includes mounting gasket and hardware.
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.
Hear it NOW with our PPE Long Tube Header in SCCA Autocross.
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!

With a factory midpipe and headers, this muffler is just right. There is a tiny bit of drone with the top up but it's not really in the rev range you use on the highway. It doesn't matter since the tone when you step on the gas is so good. Highly recommended.
amazing and wonderful, I've only had this for one day so I don't have any info on it breaking in after 500 miles of so. The rest of my exhaust is stock, and it sounds very nice, like you spent good money on a muffler. Not raspy or tinny at all.
I was originally thinking I would get the street muffler but decided to save the money and get the race. So glad I did, sound is so much better than stock. Not too loud but car is completely stock aside from the race muffler. Can be a touch "droney" above 3k rpm, but wouldn't want it to be any less loud since its so much fun to rev out around town. Buy it, you won't regret it!
Sounds great only had it on 1 day so take what you want. I just have the carb legal magnaflow header (live in California) and a AEM cold air intake and this muffler. At idle it's quiet and has a deeper tone then stock, it's not unbearably loud but just right I think and it's only noisy during acceleration and deceleration in gear. I don't hear any droning noises on the free way. I'm satisfied with it.
Awesome is the only word I would use to describe this product! Sounds fantastic, especially with the BAFFLE inserted. There is an ever so slight highway drone WITHOUT the baffle, but once the baffle is in this muffler sounds perfect. There are many many many burbles/pops at decel! Would highly recommend getting this muffler, so light too!
After tons of videos and forum posts, I finally made my decision to buy the RS Race based on GWR's reputation for quality and great customer service along with the amazing sound this little muffler makes.
My package arrived on the exact date it was scheduled to. My purchase was safe and sound in a rather large box with formed foam protecting it. When I first held it in my hands I could tell it was of top notch quality and I was very eager to get it installed on my mx5.
Installation was a breeze. What I did not expect, was my old exhaust not going down without a fight. Its former Ohio home had left it with rusty bolts that rounded very easily (partly my fault for not using heat). So I took the car down to my work. To make a long story short, I cut it out. Once the 25+ lbs carcass was free from the mid pipe, I went ahead and just cut the hangers as well. Tip: if you have questionable bolts USE HEAT, real heat from a torch or you will be cussing and cutting everything out as I did.
After everything was out, I used soapy water and got the hangers nice and slippery and got it hanging so I could get the pipe installed. I then found that no matter how I positioned the pipe, the gasket would not seal my mid pipe and RS together without leaks (yes the hangers were slippery). Thankfully, I had ordered an extra gasket from GWR anticipating this. I double stacked them and got everything lined up and it sealed perfectly without having to 'jack' the pipes together with the bolts.. Not sure if this is the proper method, but it worked great for me.
The sound is amazing. Once the car is warmed up, you can hardly hear it at idle. At lower RPMs, its modest but you can expect some cabin noise and nice burbles and pops on decel also at shift points around 3.5k (the burbles and pops seem to get better and more audible after about 500 miles). Just granny driving around town it doesn't seem to bother anyone under 3.5k. When you step into it, that's when you'll fall in love. It starts to scream at you and get very raspy. In a VERY good way. Definitely reminds me of old British roadsters. Just wait until you go through a tunnel :) YouTube videos do not do the RS Race justice. It sounds PERFECT. If you don't mind some noise (good noise) and a small amount of drone in 6th in between 2-3k this is the ultimate pipe you want in my opinion.
Excellent muffler, sounds great and so much less weight for a little under powered car. This muffler really adds to the Zoom, Zoom. The write up says: 'One observation we have made is that customers under age 30 seem to consistently feel it is just right, not too loud'. We believe it should say 'under age 30 and over age 60' instead.
I have had this exhaust for a few months now. As a teen I worked for money to pay for it myself. Probably one of the best purchases I have made. I have auto-crossed go-karts since I was 5 and 12 years later my dad bought me my own Miata. Naturally it is set up for auto-crossing with some coil overs, 17 inch tires and some 3 degree camber. My dad loves this exhaust, he doesn't want to make it louder, but I have other plans. It's not as loud as his 2013 Scion FRS with a Spec D tuning exhaust. I have been looking at the mid pipes, but they all take away the drone, and that's my favorite part. But we'll see how it goes.
I previously had the RoadsterSport II muffler. I decided to try out the Race single after listening to another Miata with that muffler. I wanted a bit more volume and pops.
This muffler has a great sound and very little drone/boom compared to the RS II, but it needs a bit of time (200-300 miles) to settle in and quiet down a tad. The first couple of weeks were a bit loud but not completely unreasonable.
Holy Crap. Right now I've got a completely stock exhaust system besides the Roadster Sport Race muffler. Swapping from the Stock muffler involved very little prep work. This car lived 95% of its life in Michigan being driven during both winter and summer, so the exhaust flange bolts were significantly corroded. Twenty-Four hours before installation, I sprayed both bolts with PB blaster, then waited until the next day. In the morning I sprayed again before work, then again after a seven hour shift. When the exhaust had been delivered (which only took two days from time of ordering!) the breaker bar easily loosened the nuts. The sound is absolutely amazing! I grinned from ear to ear after the first startup. As others have already stated, the craftsmanship is absolutely flawless. Right now, I think it's probably the perfect noise level for me; at least until I replace the mid pipe due to a separating catalytic converter. The pops and burbles audible alone after the install make this muffler worth the price tag. Do yourself a favor (and your Yata) and purchase this muffler if you're still running a stock exhaust.
Awesome pipe, I think it works well with the stock header and mid pipe for now, good sound & not too much! Thank you GWR!
I first purchased the street single and liked it with the stock header & mid pipe, needed a little more though so I bought the race single. This is much better in my opinion till I change the header/mid/turbo down the road then maybe throw the street single back on with a baffle if it's nuts... Thank you GWR!
