Description

The RoadsterSport 4 Muffler is an aftermarket exhaust component designed for 1999-2005 Mazda MX-5 Miatas. It is constructed from T-304 polished stainless steel and features a Helmholtz chamber to reduce standing wave 'boominess' in the exhaust system. This muffler includes removable baffles to control sound level and comes with mounting hardware, a gasket, and a lifetime manufacturer warranty. It fits both automatic and manual transmissions.
