RoadsterSport "SUPER-Q" Stainless Steel PREMIUM ADJUSTABLE Sound MX5 Miata Exhaust
2006-2015
Our Best Selling NC MX5 Miata Muffler!
PART NUMBER: 60-13372
DESCRIPTION
Our Best Selling MX5 Exhaust! The SuperQ is our ONLY muffler designed to handle the massive sound increase that comes with header change. Therefore, SuperQ is our strong suggestion if you might change headers. The RoadsterSport2 was designed for fun on otherwise stock car, wasn't designed to handle massive sound increases of the header change.
Our Best Seller!
Promised for years and we finally got it done, a revised version of the famous RoadsterSport Q that is even more successful at controlling sound for customers making modifications such as highflow headers and superchargers. This is also our top recommendation for customers with automatic transmissions, and or customers with the PRHT hardtop, or any customer wanting something deep and throaty when they put their foot in it but not shouting at them when they are just in cruise mode.
This attenuation design is a premium "NO-DRONE" choice, great for those with manual transmission and especially for those with the AUTOMATIC transmission (which tends to keep the RPMS in the lower ranges). By using smooth mandrel bent 2.5 inch tubing to redirect the flow for a side entrance to the muffler we engineered a sound wave attenuation first chamber to knock down volume level dramatically while maintaining a flow-through design. This attenuation chamber design muffler is the most mild and mellow on an otherwise stock MX5 Miata...about 10 to 15% louder than stock...with a deep sporty burble anytime you hit the go pedal but quiet when you are just cruising.
This premium MX5 muffler is also the BEST choice for those who plan such additional mods as a supercharger or header change (a header change unleashes a massive amount of additional sound). Our latest and best dyno results for an otherwise stock Miata....and for modified Miatas with the header change all the way to supercharged were obtained with the RoadsterSport Q muffler. ALL THE FLOW, without the noise!
Yes, simple BOLT ON that bolts to our midpipe, or the factory midpipe, or our Racing Beat midpipes. INCLUDES New Gasket and fresh Nuts and Bolts to make your install super easy. Weight is 24.5 pounds with baffles removed, 26.5 pounds with baffles installed (stock muffler is over 27 pounds).
Finished in tips which INCLUDE our exclusive baffle cone inserts which are REMOVEABLE and allow you to set the sound to sporty...or quiet. Also available are optional packed baffles (see separate product description) with which you can quiet it down even more for those using a header or supercharger, or race midpipe, etc. This system is 10% to 15% louder than the stock Miata muffler on an otherwise stock MX5 Miata exhaust system....and only 25% over stock sound level when used with our complete 2.5 inch RoadsterSport header and 2.5 inch RoadsterSport midpipe. Baffles are retained by small hex bolts inserted from well under each tip.
Proudly made in the USA with a LIFETIME WARRANTY, emissions legal in all 50 states! Fits all 2006 and newer Miatas with manual or automatic transmission, soft top or retractable hardtop.
Installation of this Miata 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! Installation notes on our forums --- CLICK HERE TO READ MORE. This Miata exhaust is guaranteed for as long as you own your Miata.
BRIAN'S APPLICATION NOTES: Everything we have learned about MX5 Miata exhausts, all our best tricks, have gone into this RoadsterSport Super Q. It is the perfect FIRST MODIFICATION and still the best choice for anyone planning future upgrades such as a header change or supercharger. It is quiet when you cruise down the freeway but delivers a sporty deep burble when you push your foot harder on the gas. This Miata Exhaust is the choice on my own soft top MX5 for driving around town...and my wife's PRHT MX5, and my strong recommendation for anybody wanting an exhaust with a super smooth burble, or any owner planning additional exhaust changes (header change or supercharger). This is also our top recommendation for owners of the automatic transmission and Power Retracting Hardtop. Does NOT fit with most hitch setups, both items trying to live in the same space and the hitch can damage the muffler.
Even more impressive than the peak horsepower gains is the broad torque gain from low to middle rpms, as shown in the dyno report from our forum 2012 project PRHT which you can read more about in our forum
MAY 2012 Update: New Rolled Tip Design! Had many requests for a new thicker rolled tip. The problem with the rolled tips that all our competitors use is that they are very heavy, which helps partially explain the ugly fact our competitors don't want to admit...which is that most our competition is HEAVIER than the stock muffler. As a famous racer once said, weight is the enemy, and making a muffler that is heavier than stock and calling it a 'performance muffler' is not our style here. It took a big investment in new equipment to come up with a rolled tip that didn't add weight to our best performance design...but it was worth it. These new dual 3.5" OD outlet tips complete the look of the exhaust and provide a more aggressive and sporting appearance. Yes, still works with, and includes, our unique removeable baffles that put YOU in control over final sound levels.

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).

RoadsterSport "SUPER-Q" Stainless Steel PREMIUM ADJUSTABLE Sound MX5 Miata Exhaust
Super Q sent in a big box with molded packing- preserved nicely! I immediately took out the baffles. Why buy this if you want quieter? Tip #1: hold the nut still while you ratchet out the bolt that holds in the baffles or you can see the scrapes inside later on. Overall this job is described as "easy." Ain't nothing easy. The 2 bolts that you must take out are pretty easy. Break the tension with the heel of your hand with a 14mm ratchet. As you spin the nut off, it gets harder because the bolt is rusted- keep going. Now it gets harder because you now deal with the rubber bushings. This part stinks. The big tip is to use soapy water. I did this, and 2 of the 4 bushings are pretty straight-forward. The other 2 are a *****. Tip #2: Ramps work well. Tip #3: I found that doing it in this order worked the best: Start on the driver side and get out the easier bushing (back left.) Make sure the middle muffler is free from the bolts. Now wrench the whole thing to the passenger side while making sure to get that soapy water in there- it comes free with much persuasion. Now go to the passenger side (Tip #4: i used a jack stand to hold the muffler up-it's heavy) and then do the front easier bushing. The easy ones are caddy-corner (opposites.) now the force of the whole old muffler system can be used to leverage the 4th one off. Wheww. Now it's easy. The new system doesn't have the "mushroom" hangers (unnecessary little bast****) so just fit them in. I video'd with OEM, without any muffler, and with the Super Q. I will say that the Super Q is a lot like no muffler (deep growl) but controlled sound while driving around. The muffler tips are crazy bigger but I think they are BOSS. Great job, GOOD-WIN!
I recently purchased 60-1328 RoadsterSport HighFlow Stainless MX5 Miata Midpipe with HighFlow Converter and 60-13372 RoadsterSport "SUPER-Q" Stainless Steel PREMIUM ADJUSTABLE Sound MX5 Miata Exhaust
The combo of the two is nothing short of fabulous. Quality and fit and finish is absolutely wonderful. The sound is so good. I have been running them WITHOUT the included baffles in the SUPER-Q. It is a tick louder than stock, but the tone is so much deeper and aggressive. There is a slight burble when revving and on upshifts. NO DRONE top up or down. I was considering on adding a header too but almost afraid of messing with a good thing! :-). I am thinking the catted header could be a good option.
If ordering do not forget the bungs to close the 02 sensor holes in the mid pipe unless you are relocating the midpipe there.
I combined this with a Tune and there is more low end. Cruising around 2500rpm and putting the foot down no longer requires a downshift.
I have the complete exhaust consisting of the MaxPower catless header, Helmholtz midpipe, and SuperQ muffler. The SuperQ combined with the Helmholtz mid-pipe do an excellent job of taming the drone from the header, as I don't notice any when cruising between 2500 and 3500 rpm. It's quite sporty when accelerating (particularly when you're in a canyon or under an underpass), but quiets down to reasonable levels when cruising steady state. I get pops on downshifts, thanks to the header. I did install the optional baffles to tame the noise level somewhat, as with the standard baffles the noise level was a little too high for comfort, particularly when I pull a small cargo trailer. I've had the system installed for 35,000 miles and it still looks and sounds great.
I bought the Super Q a while ago for my 2009 Grand Touring automatic. Great quality, bolted in place easily (use lots of lube on hangers!). I also have installed the RoasterSport Street Header with cat (yeah, I know not made for an automatic but with some engineering to reroute the trans cooling lines, probably one of the best mods I have done!). Also, the OEM mid-pipe is still in place. My first drive was a long distance trip from MO to PA. Sound was ok but droned from about 2700 RPM to about 3200 RPM. Luckily I cruised around 2500 RPM. Now after a few more miles and "spirted" runs with my local Miata club, the muffler has settled in and produces a nice mellow/throaty sound (no baffles installed). Still drones at same RPMs but not in that range on runs, only during acceleration which is not objectionable. I have had club members compliment me on the sound asking what I have done. I would recommend the Super-Q and also the catted header (if required due to emissions as was for me).
So I bought this muffler as a starting point before I get into my 2.5L engine swap, and my current 2.0 Doesn't have any special modifications outside of a cold air intake. This thing sounds wonderful! I took both baffles out, and it has a wonderful little growl, especially at startup that always puts a smile on my face. I wish that it had that deep undertone throughout the rev range, but again that's not what this muffler was made for. It's a very tame, quiet exhaust upgrade for whenever you just want to cruise around town, and especially on the highway, which is where I put a lot of miles on traveling to and from work.
As I'm on the younger side, of course I would love more sound, but I plan on getting there once I finish my 2.5L swap, and get a header and the Hemholtz exhaust, which I will update with once I have everything together. All in all though, I love the way that this muffler really can give me the noise that I want, when I want it, and then keeps my cabin nice and quiet when I don't :).
Installation went well- everything lined up and the mating joint was perfect with no leaks. Quality is excellent with nice welds, solid construction, and a smooth finish. It is quieter than expected and that's without the baffles. There is some drone at certain RPMs- 2500 at cruise and 3000 on decel for instance- but that's pretty easy to avoid. I've had my Miata GT PRHT for a year and 5000 miles. It's stock with just the exhaust changed and it will stay that way. Top is never down. Very pleased with the exhaust overall, although a bit more volume would be nice. It is a very subtle exhaust and will not offend neighbors or bystanders.
I'm really pleased with this choice. With top up, you can barely notice anything different between this and stock. With the top down, the difference is very noticeable in a great way; not too loud, not too buzzy, but just right (IMO). The bigger diameter exhaust tips are also a nice touch and help to fill out the cutout in the bumper. Great product!
Excellent choice! Lighter, smaller and much shinier than stock. Went with just the Super Q muffler and it is a smidge louder than stock. Baffles were pulled before install. Nice burble when you start it up and when idling at a light, you can FEEL it in the breast bone... just enough to make your heart go pitty pat :D Very happy with the sound and it took 45 minutes from pulling into the garage to the video clip of first start up. Easy mod to do and makes the Miata smile even bigger. Thanks GWR, for an excellent product.
This is my second exhaust purchased from Goodwin Racing & it has not disappointed! My first one was their RoadsterSport 3 Muffler along with MagnaFlow Midpipe installed on my 2003 Miata in 2015 & I absolutely loved it!
Fast-forward to 2021 & my 2015 MX-5 Grand Touring PRHT with its OEM muffler, which was definitely uneventful! Since the RoasterSport 3 was not available, I decided on their RoadsterSport Super Q. I was concerned that it might be too quiet for my taste, but I live in a quiet neighborhood & didn't want to go too loud & annoy my neighbors.
The installation went very smoothly, especially with the recommended soaping of the hangers & took about half an hour. The baffles were immediately taken out.
It is very quiet from inside the car with top up & I wondered if I'd made a mistake with this muffler. I would agree that it is about 10-15% louder than stock with the baffles out. But, WOW, when driven with the top down, you can hear its great throaty sound! Much, much improved over stock! I wish it were a tad louder, but its sound is marvelous! If I want it louder, I could always add a midpipe! Thanks Goodwin for another winner!!
The stock Miata sounds like a typical 4-cylinder entry level low, cost car. The Super Q has a nice sound worthy of a four cylinder sports car. Installation is easy and build quality is excellent. The good sound adds to the fun factor without adding a high noise factor. There appears to be a modest performance enhancement too.
I'm very impressed with my exhaust. It sounds great but is quiet when cruising which my girlfriend really likes. It has awesome burble during deceleration. I looked at it closely before installation and it is very well made. Installation was a breeze (except for a super rusted bolt on my car) and the exhaust was a perfect fit of OEM quality. I highly recommend.
August 23, 2020 just installed the super Q muffler on my mica red mx5 which was purchased new in 2009. I did remove the baffles before installation. The car is only driven in the summer with only 7400 miles and is in showroom condition. It sounds great now and has a deeper exhaust tone and no drone. Love the little burbles it makes on deceleration and downshifting. The mid-pipe will be next. I have also ordered the Moroso coolant recovery tank and power steering tank in black powder coat. New Michelin pilot sport tires installed this spring, it is good for many more hours of fun. Thanks to everyone at Goodwin for there help, great people to deal with.
