There are 2 versions of our dual inlet S and GT3 mufflers, Sport and Street, which may be getting confused.
Our Sport mufflers can be identified by a 26" wide case with unbaffled tailpipes. They are very aggressive which increases the opportunity for drone at specific RPMs depending on several factors.
Our Street mufflers can be identified by a 33" wide case and baffled tailpipes. They were designed for locations with sound level restrictions and for those who are looking to mitigate drone.
All street mufflers come with baffled tailpipes. The tailpipes for both Street and Sport are removable which allows the Sport mufflers to use the baffled tailpipes of the Street version or hidden caps, creating a hybrid of sorts. This is all done to give options as everyone has their own perception of sound volume and quality.
