Mazdaspeed exhaust and midpipe

Mazdaspeed exhaust and midpipe
Mazdaspeed exhaust and midpipe
More power and faster spoolup for the Mazdaspeed MX-5!

Made in the USA

Exclusive to Flyin' Miata

Availability: In stock



Exclusive to Flyin` Miata and designed specifically for the Mazdaspeed MX-5, this exhaust will improve spoolup and support higher boost levels when paired with our downpipe. We measured a 23 hp and 26 lb-ft increase on our dyno. A handmade muffler allows the exhaust note to be a little deeper and a little louder, but still well behaved. It`s the sound the car should have had from the factory! It`s also the performance the car should have had from the factory, really.

Adding the exhaust system alone will allow the car to reach peak power 300 rpm sooner than stock and will save 6.5 lbs. Why did we not use the standard Mazda flange locations? Because we found that this design gave better performance and less noise. It`s also easier to build. And as a bonus, the whole system has a lifetime warranty. Warranty details.

For Mazdaspeed MX-5 only, not compatible with any other models. Legal in all states, including California. Legal for Solo II in stock class.

The FM midpipe flange and the factory downpipe flange use a different gasket in order to seal the exhaust system. We are aware the seal is not perfect and we found the best seal can be obtained by using the factory donut gasket. This imperfect seal will not be an issue with a Flyin` Miata downpipe. Lifetime warranty. 2.5" piping, 3" polished tip.

04 Speed Miata Complete Exhaust
I finally purchased the complete front-to-back exhaust to complement the cold-air adjustable boost air intake. Wow!! What a nice sound and the engine performance....a completely different car. I agree that this is the way my 2004 Velocity Red Miata should have come from the factory!!

First or last, this upgrade should be on your list.
If you havent bought this for your car yet, you should. This has given the car more smiles per gallon than anything else I've done. And I've done a lot!

Great sound & great look!
Absolutely beautiful exhaust with wonderful build quality. My only regret is that I have to stick it under the car where it will get dirty. Installation was simple once I removed the ladder brace under the diff. I also liked that I could adjust the exhaust tip exactly where I wanted it. Having that in/out & up/down adjustment made it look great after install. I have this paired with the FM downpipe and the sound is perfect. Has a nice growl on startup, but doesn't get annoying during normal driving.

Happy with complete FM intake, downpipe and muffler system
Already had FM intake kit and downpipe. Sounds good, but not loud, runs great, should have done this years ago. Greatly reduced droning with top up, compared to previous straight thru exhaust

A must have combo!
Good, God! I've been sporting the FM downpipe for a little while now. And it did make a nice difference in general response and sound of the MSM. However, this is the missing link to making the car what it should have been like from the factory. I'm really surprised FM doesn't offer the three-piece stand-alone downpipe to exhaust package (at a small package discount of course) to put more of these systems out in the wild. This really wakes up an already wonderful car. Beautiful fit and finish, nice throttle response, wonderful sounds. If you have an MSM, you need this! Seriously, click the "add to cart" button, now.......

Bought as a Christmas present to myself, including the downpipe, last Nov, but didn't get installed until this week. Geez, its like a different car, smoother, better shifting, more torque throughout the rpm range. And the sound is excellent.

Very happy customer!
Nice and tastefu sound. Not over powering nor is it too quiet. Highly recommended for your msm!

10/10 I do recommend!
I'm glad I chose this over any other option for my MSM! Clean, easy and fit as it should. The exhaust note (paired with FM MSM Downpipe) gives a nice, deep note without excess drone or being too loud, but just enough to make the alarms go off (haha!), which is exactly what I was looking for going with a new full exhaust system. Spools smoother and boost feels more linear than before. The 3" polished tip doesn't look all too shabby either; a must in my books for any MSM owner!
