COMPLETE PREMIUM HELMHOLTZ CHAMBER Cat-Back RoadsterSport 4 Miata Polished Stainless Steel Exhaust for 1990-1997

COMPLETE PREMIUM HELMHOLTZ CHAMBER Cat-Back RoadsterSport 4 Miata Polished Stainless Steel Exhaust for 90-97

FOURTH GENERATION UPDATE....A revolution in exhaust technology finally available for all 1990 through 1997 Miatas, our new HELMHOLTZ exhaust system features a standard resonator in the connecting pipe to lower volume and rasp and an exclusive all Helmholz main chamber at the back that massively reduces the standing wave inside the exhaust system! Cuts the boom frequencies of 120-130hz by over 40+db inside a top up Miata cabin which is a common source of complaints with aftermarket exhausts on the Miata. Result is all the FUN throaty sounds you want, without the drone levels other systems make that wear you out on long uphill and downhill sections of road. 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.

Muffler section is 16.5 pounds...and included connecting pipe is 8 pounds (less weight than most choices).

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 help 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.
