This 3.50 Auger Style Muffler is one of the best ways to reduce the most sound without reducing the power. The auger style design does not reduce the area of the exhaust system while still spinning the exhaust 360 degrees to break up the sound. Lightweight (only 1 lb.) and very effective. Typically reduces the noise by 6-7 db. 11.00 long. Designed to fit inside 3.50 I.D. tube.
