Customer Reviews: RoadsterSport 3 Polished Stainless Steel Miata Exhaust Muffler 1999-2005
Had this installed by Rocky's Miatamotive, next door to Goodwin Racing, at the same time as Rocky installed my new CSF 42MM Radiator, also purchased from Goodwin.
The OEM hoses were not in horrible shape but made sense to upgrade to these Silicone hoses since I was having the higher performance radiator insalled. Got them in blue, they look great and I have every confidence they are going to perform well.
Can't beat the convenience of having the Yoda of Miata to work on my car right next to the Yoda's of Miata Performance parts right next door with parts in stock.
Glendale cops don't like my Magnaflow system so I bought the roadstersport muffler because of its adjustability and because I knew it would complement my roadstersport midpipe nicely.
It comes well packaged in the box and looks great on the car. The tip is smaller than the Magnaflow I had, but the piping of the system is bigger overall, so at least there isn't that awkward transition from 2.25 inch piping to a 4 inch tip like on the Magnaflow system. The rolled tip is a nice touch too; makes it look like a really high quality stock part.
I started the car a went for a test drive with the baffle in. The car was a lot quieter. I started to miss my Magnaflow. I went home and unbolted the baffle near the tip and went for another drive. This brought some of the roar back, so I left the baffle off. Set up like this with no baffle and my matching roadstersport midpipe, my car is loud, yet refined. There is no rice at startup like there used to be and there is practically no drone on the highway. It still sounds great in tunnels and I got complemented on the tone from a guy in a modified FR-S the same day I put it in. There seems to be a bit of a seat-of-the-pants improvement in power as well. Overall a great system.
Purchased this muffler after researching mufflers on the internet, listening to sound bites, and speaking with Sean. I was looking for something to increase the exhaust sound, but not be obtrusive.
Shipped quickly and on time.
Unit arrived well packed and very shiny. Really nice muffler.
Blocked front wheels, jacked up and blocked rear of vehicle, and dropped old muffler the night before the new one was scheduled to be delivered. Used a spray bottle with Dawn dish detergent and water to lubricate rubber bushings. Slip a screwdriver in between hanger and rubber bushing, careful not to tear, and squirt solution in gap. Did this all by myself in 30 minutes.
New muffler arrived and it only took 15 minutes to install. Use packing material to support muffler under hangers, lubricate rubber bushings with Dawn solution, slip hangers through rubber bushings, put gasket over bolts, put on nuts, and tighten alternating between bolts.
Funny thing happened. Fired her up, stepped on the gas, and was surprised that it didn't sound much different then my stock muffler. Took it for a drive down the road, same thing. Well, the unit is shipped with the baffle installed, which I thought was an extra add on. The glass packed baffle is an add on, the regular units are all shipped with a baffle.
Anyhow, took the baffle out, and was pleased to hear a nice sound, not too loud, not too quiet. Just about what I wanted.
Do not be afraid to deal with Good-Win-Racing. They are top notch and very nice to work with.
Fast delivery and securely packaged.
The exhaust was well built and easy to install.
The exhaust tone is deep and throaty during heavy throttle. I like the fact that it is not ricey....
The exhaust not is fine during long trips. I have never drove it with the baffle installed. I'm sure it is quitter, but I am happy with it removed.
Excellent muffler/axleback. Unfortunately for me I picked this up the hard way and ended up spending more money by buying a generic muffler thinking I'd be satisfied with something cheap. So 300 dollars turned into over 400 but lesson learned, do it once, do it right. The RS3 muffler has the perfect tone and fitment is spot on. Pick up the glass packed baffle at the same time though if you have the midpipe as that's a great feature to have different sound levels depending on your use (or mood). I couldn't be happier with the RS3 and wish I just bought this setup from the start.
The RoadsterSport 3 was shipped and delivered within a week of ordering. Just like everything else I've bought from GWR, it was a very speedy delivery.
Installation was a breeze, except for the stubborn rubber flanges. Soap definitely helps.
Here's how the exhaust looked out of the box:
Compared to the shabby stock unit with 90K miles on it:
And, finally, here's how it looked on the car:
I'm happy with the sound, the look, and the price!
Installation was very clearcut and flawless. Sound is excellent. Product finish and looks are top notch. I am very pleased with my choice. Also installed a K&N cold air intake at the same time.
Currently have 100 miles on it and it has just the perfect sound that i expected.
Shipping was lightning-fast and installation was quick and easy. I was worried about having ricey civic-fart noise, but this exhaust has deep, good quality sound. Getting daily compliments and having fun in it. (removing baffle makes the sound wa---y better:))
I've had my RoadsterSport for just over a year and I still love it. The sound is perfect. It has a nice burble at low rpm and sounds downright mean when you really get on it. There is no drone or "riceyness" to it, and it is quiet enough that your neighbors won't hate you. I'm also very impressed with the quality. My roadster is a true daily driver that has been through salt/sand all winter, tar and gravel from construction, and everything else sharp, sticky and corrosive you find on the road. The muffler is still as shiny as the day it arrived. If you are looking for a great sounding, high quality, visually subtle exhaust, I say good luck finding one better than this.
