Proper Sports Car sound with a deep mellow tone at cruise and a vintage bark when you put your foot into it....our premium Miata exhaust choice. Smooth perforated core and smooth bends for max power.
This Miata exhaust is the ONLY 90-97 Miata exhaust with adjustable sound! Includes fresh stainless nuts, bolts and gasket to complete your install. Includes our unique removable baffle cone tip so YOU are in control of the sound level and can adjust for extra sporty or calm it down to mellow for longer trips.
ALL STAINLESS STEEL and lifetime warranty! INCLUDES COMPLETE MIDPIPE section so that it this is a COMPLETE BOLT ON solution from your converter flange back. Built in solid 304 stainless steel and completely polished to a mirror finish, this premium Miata exhaust is our only choice that incorporates a big Helmholtz chamber to control drone and a baffle insert that gives YOU control over the final sound level (baffle in is about 15% more sound than stock, baffle out is about 25% more sound than stock...so you always have a choice for those longer trips). And, you always have the additional option of our packed baffle to calm it down even more, which are sold here separately on this website....for a total of THREE different sound levels from the same exhaust. With an ear pleasing exhaust note, great price and easy installation this Miata exhaust is a great beginning for Miata performance modifications.
BRIAN'S APPLICATION NOTES. We did helmholtz chamber exhausts for NC and ND generation Miata and got lots of requests to bring this technology to the NA application. Every other choice on the market is essentially just fiberglass with perforated tube in one shape or another and fiberglass kills the fun sounds while doing a poor job of killing the BAH-AH-AH-AH DRONE you otherwise can get in small 4 cylinder cars. Rear can in this setup has no fiberglass and instead uses tuned valve Helmholtz chamber that acts like a little air piston and cancels out the standing BOOMINESS. Result is that this is the FUN without any downsides choice among our many choices...all the fun when you plant your foot hard but mellow and refined when you just want to cruise and hear the stereo, etc. Includes the connecting midpipe which is a separate cost item with some of our other choices (Racing Beat). The slightly larger tubing of the RoadsterSport Miata muffler means a slightly deeper tone and a little more burble on decel than the factory exhaust, 2.25 inch tube size all the way and finished with 3 inch tip, SMOOTH bends, straight through SMOOTH perforated core design for maximum horsepower.
This Miata muffler carries a LIFETIME WARRANTY, built from all polished stainless steel and is made with pride in the USA. See dyno work on this exhaust below!
