Porter's Standard Length Muffler

Body Length- 20" Overall Length- 26" All Porter Mufflers are non-directional, allowing them to be mounted in either direction. Exhaust gas passes through the center of the steel spiral core with the sound dissipating into the stainless-steel packing preventing drone. Unlike glass-packed mufflers, our steel-packed mufflers will never break down.  Our mufflers are designed to create a slip fit lap joint with your mating exhaust tubing. We suggest welding this joint instead of using band clamps as it will perform better over the length of the muffler and create an air tight seal. Created back in 1931, our first ever product, that has set the standard for the future of our company.  To continue our tradition of quality each Porter Muffler is handmade using only the best heavy gauge and high quality steel products sourced in the U.S.A.
