Customer Reviews: RoadsterSport RACE MX5 Miata Muffler, Just 8 pounds! 2006-2015
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!
It's been on my ride about a month now. And. . . I LOVE IT!!!
It could be louder for my taste. But, I do like the tone. I run most of the time with the top dropped.
If there was some way to get the British Sports car tone of my MGB, it would be perfect. But, it's still a 5 Star product. Easy to install. Looks great! Sounds great!
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 Ã¢â¬ÅjackÃ¢â¬Â 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.
Ordered this exhaust 1 week ago. It was delivered in 4 days and after much anticipation I decided to jump in without having done an exhaust install before. Took about 15 min with an impact gun and some pb blaster. Now I have fallen in love with this car 1 million times more. If you don't have an aftermarket exhaust you NEED one.
As for the sound, it is everything I personally wanted. I have a stock header and mid-pipe but I still wanted a loud exhaust. Im able to hear my car at idle and maybe a few small pops on decel. If it was any louder I might have complaints but I think it's perfect, I'm also not using the baffle which I'd assume would quiet it a bit. I love this exhaust, and can't even imagine how it would sound with a header and mid-pipe
Somewhere between 5k and 10k miles later review*
As advertised! I have otherwise stock exhaust so for those of you looking to start with upgrading the back box listen up
Initial: (w/o baffle) low deep tone. Pleasant, some garbles and light pops on decel, noticable boominess on decel and low RPMs under load (which i expected) drone on the highway is definitely not unbearable, better than an NA with Roadstersport3 setup. I commute about 30 mins on the highway to work every day and it really wasn't bad. When you get on throttle its a loud but still warm tone, deep and pretty throaty, no annoying swarm of bees or anything.
(W/baffle) my god, the wooshing noise coming through the baffle is something else! I had a friend record it as i drove by, its quite the sound! Under normal driving the baffle cut back the drone pretty good too so it was a win-win!
8k miles(ish) later
Oh man once this thing breaks in? (Around 1k miles) WOW. Nice and throaty, not much louder, so many more POPs and garbles on decel and in between shifts. Just perfect. And either i got used to it but i think it may have gotten less boomy too over time.
Beautiful piece. Came quickly and well packaged. This muffler is very light. Install was simple, and sounds great.
I'm using this exhaust on my daily driver with stock headers and midpipe. The exhaust produces an aggressive sound, with light burbling on idle, high pitch growl near redline, and an occasional pop during deacceleration.There is not much drone on city streets, but a lot of it on the highway (2.7K RPM to 3.6K RPM). This exhaust is loud.
The baffle highly improves this exhaust, it kills most of the highway drone and brings the dbs' to the perfect aggressive daily driver kind of level.
Installation was easy; make sure to use dish soap to get the exhaust into the hangers, it'll save you a lot of time and struggle.
This muffler makes me want to drive this car faster. This muffler opens up a lot more noise from the engine if you want to listen to your car while you drive or even autoX. YOU MY FRIEND IS IN FOR A GOOD TIME. Have fun all roadsters fan.
Seriously couldn't be happier with this new muffler.
The exhaust note takes me back to my glass-pack mufflered 68 Datsun 1600. The bubbling sound during downshift, the throaty note during acceleration, and the reduced pressure on the exhaust system makes the shifts feel smoother.
