Add FUN right here with one of our best selling MX5 Miata Exhausts!

Good-Win Racing makes and sells more MX5 Miata Exhausts than any other company, and we use that experience to help YOU find the best MX5 exhaust choice. Click on our choices below for extensive descriptions, pictures and even videos to help you pick the right exhaust to maximize your Miata fun!  Customers considering our standard length header should look to our special header version SuperQ for a muffler that can handle the sound unleashed by that header swap.  The rules change quite a bit with our longtube header because of the massive midpipe resonator it includes, which allows use of that special header setup with any of our muffler choices.

Brian's General Application Notes.  Sound preference is VERY SUBJECTIVE, some want more sound, some want less.  And there are other considerations such as pitch, generally the single tip designs have a higher and more exotic sound.  Result is that our entire team prefers the higher pitch sound of the single tip designs, whether we are talking our quiet "SuperQ" or more aggressive volume choices like our SuperStreet or Race mufflers.  But many customers prefer the twin tip looks and lower pitch, to each their own, and they will generally prefer a dual tip whether it be our SuperStreet Twin Tip, or the Super-Q Twin Tip, etc.  We have numerous videos in the product descriptions below to help you decide which choice you prefer.  All owners considering further modifications such as performance headers, performance midpipes, and superchargers, are strongly encouraged to consider the RoadsterSport SuperQ 'Header Version' designed to handle the sound unleashed by a header swap.

Note that EVERY brand of exhaust we offer will unmask the burble and 'pops' of unburned fuel that are NORMAL in every exhaust system but normally below the hearing ability of the average consumer.  If you have no idea what I am talking about in the last sentence then please go on YOUTUBE and search "sports car exhaust pops" for a quick education.  Funny story about exhaust 'pops', when the good folks at BMW designed their MINI they wanted to make it feel less econobox and more sports car so they included a highflow exhaust from the factory so consumers could hear the fun pops from the first test drive.

REVIEWS

Brian, just wanted tyou to know you've got another highly satisfied customer. I got my RoadstersportIII muffler on Friday, installed it in 20 minutes, looks and sounds awesome. I like the baffles out!! My new tires/wheels came Saturday, just got them on and test drove them. Fantastic!! And how they look--- just what I was after. I will add the front "mud flap" that looks like the rear one, for some stone protection, but the offset was just what I was working for. I'd love to send you some pictures for your photo gallery. If you'll send an adress via e-mail, I'll send some high-res photos showing clearances and side profiles, etc. The graphite spokes and polished rims really set well on my black car. Thanks again, me and my wallet will be back!!

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.
