Our original duals for the 2006 and newer MX5 Miata was the best selling Miata exhaust by a good margin. Messing with the successful design to improve it was approached cautiously. We learned on the dyno in testing for our new header coming soon 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, this high quality Miata exhaust is our only choice that incorporates a 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 now in stock and shipping. This Miata exhaust delivers the zoom-zoom that the factory exhaust does not. Very mild at cruise, this Miata exhaust has a nice deep purr when you step on it. The factory exhaust on the 2006-2008 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 2006-2008 Miata saves Mazda a lot of money but it alone is over 26 pounds! Our all stainless steel Miata exhaust uses the factory spacing, factory cutouts, and factory layout but saves 7 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. Adds about 8 horsepower. Finished in three inch tips which INCLUDE our exclusive baffle cone inserts which are REMOVEABLE 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! BRIAN'S NC MX5 Miata Exhaust APPLICATION GUIDE: We have a full range of exhaust choices for the new 3rd generation MX5 Miata. All of them give you better flow for more horespower, some of them save weight over the massive 26 pound stock unit. Since one man's too loud is another man's too quiet, here is how each of our Miata exhaust choices ranks in terms of sound level: the Racing Beat is about 15% louder than stock and very deep sounding, the Magnaflow comes in about 15-20% more sound than stock, our RoadsterSport II Duals is actually adjustable for a range from 15 to 25% more sound than stock depending on whether or not you use the included baffles or the optional packed silencer baffles, and MazdaSpeed ranks about 30% more sound than stock with a little more low end boominess (similar to the Racing Beat in tone but louder). The RoadsterSport RACE single tip Miata exhaust is about 50% more sound than stock.
