The original 'bad boy' duals for the 2006 and newer MX5 Miata was the best selling Miata exhaust by a good margin before the RoadsterSport Q took the sales crown. This revised version II choice remains popular as a LOUDER duals choice, great for soft top owners who like to wind out their manual transmissions to redline. We suggest those adding headers or using automatics or the PRHT (Power Retracking Hard Top) look to the RoadsterSport Q.
Messing with the successful design to improve it was approached cautiously. We learned on the dyno in testing for our header that we had ideal flow into the muffler and through the core but that the 2.25 inch connections between muffler and the tips was actually too much, and that cutting to 2 inches from muffler to tip was ideal for maintaining exhaust gas velocity and maximizing horsepower gain. The connection into this muffler remains 2.5 inches for maximum flow and horsepower.
Other improvements in this version II include reinforced hangers and more sound insulation for an even more mild sound. Built in solid 304 stainless steel and completely polished to a mirror finish, our RoadsterSport exhausts are the only choice that incorporate baffle inserts that give YOU control over the final sound level.
YES, this Miata exhaust is a simple bolt on and includes everything you need (gasket too). Already a legend, our RoadsterSport II Duals Mazda MX-5 Miata exhaust is always in stock and shipping daily.
This Miata exhaust delivers the zoom-zoom that the factory exhaust does not. This Miata exhaust has an aggressive deep purr when you step on it. The factory exhaust on the 2006-2013 MX-5 Mazda Miata is one of the few places that Mazda wasted a good amount of weight. The thick mild steel stock Miata muffler canister on the 2006-2014 MX5 Miata saves Mazda a lot of money but it alone is over 27 pounds!
Our all stainless steel Miata exhaust uses the factory spacing, factory cutouts, and factory layout but saves 5 pounds of weight and adds more of a classic sports car sound. Note that the Magneflow system is 45 pounds, which is why we worked hard to take weight off by using higher density packing and higher perforation rate cores to bring our weight below stock level.
INCLUDES our exclusive baffle cone inserts which are REMOVABLE and allow you to set the sound to sporty...or extra sporty. Also available are optional packed baffles (see separate product description) with which you can quiet it down even more for longer trips.
With the baffle out the sound on this version II is about 25% more than stock. With the baffle in the sound is closer to 20% over stock. Baffles are retained by small hex bolts inserted from well under each tip.
Installation of this Miata exhaust is SUPER EASY...just two bolts! You don't even need to jack up the car, this installation can be done in your driveway! This Miata exhaust is guaranteed for as long as you own your Miata. Proudly made in the USA with a LIFETIME WARRANTY. Fits all 2006 and newer with manual transmission MX5 Miata, automatic transmission MX5 Miata, and retractable hardtop MX5 Miata!
JUNE 2013 Update: New Rolled Tip Design! Had many requests for a new thicker rolled tip. The problem with the rolled tips that all our competitors use is that they are very heavy, which helps partially explain the ugly fact our competitors don't want to admit...which is that most our competition is HEAVIER than the stock muffler. As a famous racer once said, weight is the enemy, and making a muffler that is heavier than stock and calling it a 'performance muffler' is not our style here. It took a big investment in new equipment to come up with a rolled tip that didn't add weight to our high flow performance design...but it was worth it. These new dual 3.5" OD outlet tips complete the look of the exhaust and provide a more aggressive and sporting appearance.
