COMBO Miata EXHAUST SPECIAL- RoadsterSport 3 Miata Muffler with RoadsterSport Miata Midpipe

You get what you pay for, and this setup, while not cheap, is super high quality and sounds great. Installation was pretty straightforward, fit was fantastic and the quality of components outstanding. I have no idea if it added any power, maybe a bit but the butt dyno is unsure. I went with this set up anticipating a stage 1 turbo kit next year, at which point the high flow cat and 2.5" piping should match up well, allowing the correct amount of flow. In the meantime, sounds great, no drone, and appropriately sonorous even without the baffle. Completely satisfied.

The RoadsterSport Exhaust was easy to install in my home garage in about 2.5 hours (remove old and install new). Exhaust sounds good, but will definitely be busting the glass packed baffle for normal day to day use. A little droney at low RPM/high speeds.

As a youth I purchased an aftermarket Abarth exhaust system (header back) for an MGB. It had a gorgeous exhaust note, looked great on the vehicle, and may have improved the performance, at least in my mind. With that favorable modification in memory, I decided to purchase the Roadster 3 Miata exhaust (muffler and mid pipe) from Good-Win Racing for my 2003 Miata. The system was impressively built of polished stainless steel, looked to be of very high quality, and I couldn't wait to have it installed. I chose to have my local shop install it as I don't have access to a vehicle lift. They installed the exhaust system without any issues--according to them it was a fairly simple process. The exhaust note from the Roadster 3 system is low, pleasant, and has none of the obnoxious raspiness heard with the "coffee can" systems seen regularly on kids' rice cars these days. It is obviously a well-engineered system, tuned to have a pleasant, authoritative exhaust note, and it succeeds. The only minor complaints I have is that it can get slightly boomy at certain RPMs, and the system becomes somewhat louder as it warms up. Initially it sounds fairly quiet, but after a few miles the volume increases. I have no idea why this is the case. I tried removing the small baffle at first, but it was somewhat louder, so I replaced it. However after the system warms up to operating temperature, it seems to make little difference in volume between baffle-in or baffle-out. At any rate it's not a problem, and both my wife and I love the sound. This is the exhaust system Miatas should be delivered with from the factory. Performance improvement? Who knows if there is is difference, but the car is certainly more fun to drive now. And it didn't suffer in that respect before.

I love this exhaust! The sound is terrific above 4000 rpm, it really opens up the note and adds some great undertones without eliminating the 'Miata' sound.
The installation is easy, the hardest part was fighting with the rusted bolts (four of them total). The hanger pegs on this exhaust are easier to get on and off than the OE ones.
I purchased the glass-packed baffle with it, and while I appreciate the ability to adjust the sound level, I generally don't use it because the exhaust sounds so good that I always want to hear it! But I think that on a road trip or prolonged freeway driving, the baffle would be hugely helpful, just to save my ears!
To sum up: great sound, easy install, volume adjust options. A great package altogether!

I installed the Roadstersport3 muffler and Mid-Pipe this weekend, i gotta say, that slip joint on the mid-Pipe is genius!
I took my time with the install and replaced all of the rubber hangers with the Poly ones you sell. (If you do, install them on the muffler and mid-pipe first then to the car.) it ended up taking about 2 hours because i was prepping the car for the 350 mile drive to a weekend of racing on Labor Day. Ug, why are there still things on my car to-do list before I leave...

Over all I am very impressed with the quality when I was just in to the packaging (like a spoiled kid at Christmas) I liked how well it was packed up, to be honest, its packed better than the RacingBeat Header that I installed with the new engine I built.
The sound levels are higher and make it sound like it means business, cruising at 70MPH on the highway with the supplied baffle you can barely hear it, romp on it and its alive.

Thanks Brian and the rest of the Goodwin Racing Team.

Matt.
