Replacement muffler made by Pit Crew Racing for the 2006 to 2015 Mazda MX-5. It is the result of a lot of research from the size of the muffler & the interior mesh diameter to bring a beautiful racy sound. The cannonball type exhaust tip (taper) eliminates the muffled sound that you usually find in an open top vehicle.
