3.5 inch / 89mm Round
A 3.5 inch / 89mm Round Exhaust muffler silencer by Profusion Exhausts is by far the best available to control the vehicle sound while delivering a complementary deep tone. A 3.5 inch / 89mm Round muffler silencer is perfect to use as a resonator or a Back Box. Our 3.5 inch / 89mm Round muffler silencer in 304-grade stainless steel is fully welded for deep sound. Rule of thumb is the bigger the silencer, the quieter the exhaust sound.
