Reducing the muffler tubing to 2"" from muffler to tip is ideal for maintaining exhaust gas velocity and maximizing horsepower gain. The connection into this muffler remains 2.5 inches for maximum flow and horsepower. Other improvements in the version II include reinforced hangers and more insulation for a mild sound. Built in solid 304 stainless steel and completely polished to a mirror finish, this high quality MX-5 exhaust comes with removable baffle inserts inside the 3"" tips that give you control over the final sound level. Leave in for a sporty sound, remove for a louder sound, or purchase additional baffles for the mildest sound. Yes, this Miata exhaust is a simple bolt on and includes everything you need (gasket too). Adds about 8 horsepower. Lifetime warranty.
