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. 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 eight 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 here and at the Good-Win Racing site. 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. 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.

Absolutely love it! Gives a great tone and puts out just the rights amount of sound to me for a muffler change only. My age is 27 but I don't like my cars super loud. I will end up doing the whole exhaust and header as well, which will make the car pretty loud, I imagine, but I think the performance difference and more pure sound of the motor will be worth the sound level. Easy installation. Uses no special hardware besides the stock rubber exhaust hanger supports. Exhaust tip sticks out about 2 inches beyond stock exhaust and sets the back end off. Don't hesitate. Buy this one! ### ⭐⭐⭐⭐⭐ I love it! *by E***T on Reviewed in the United States 🇺🇸 on November 7, 2015* Installed on my 2009 Mx5 with stock midpipe and header. I took off a GWR RSII exhaust and replaced it with this. When I first put it on it was LOUD! But after around 500 miles it toned down and sounds amazing! If you like a louder exhaust this is the one for you. It has a nice tone from outside the car and a nice roar from inside. Quiet when cruising at a steady rpm on the highway(almost like it isn't there). Can't beat the price or the customer service of Goodwin. ### ⭐⭐⭐⭐⭐ It sounds great. Noticibly louder under acceleration or deceleration *by L***T on Reviewed in the United States 🇺🇸 on April 9, 2015* I have a stock drivetrain on my NC other than this exhaust. It sounds great. Noticibly louder under acceleration or deceleration. Makes it hard to save fuel. I want to hear it.Install was easy. After I got the stock exhaust off the hangers... Two bolts and all done. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/17059323-roadstersport-race-mx5-miata-muffler](https://www.desertcart.co.th/products/17059323-roadstersport-race-mx5-miata-muffler) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-27*
