Porter’s Shorty Mufflers
Body Length- 14" Overall Length- 20"
Porter Mufflers shorty mufflers are exactly the same as the Original Porter Muffler but features a 14" body length vs. the standard 20" body length to accommodate applications that require a tighter fit. The stainless steel Porter Muffler is handmade using heavy-duty 16 gauge, highly polished aircraft grade, 304 stainless tubings. Our uniquely designed interior chamber is fitted with a gapped steel spiral core and packed with stainless steel wool to channel the exhaust and make that distinctive Porter Muffler sound. 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.
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.

Arrived in less than two days, and sounds amazing! Previously I had a two into one exhaust with the regular porter 2.25 inch muffler. Sounded great and got rid of the restrictive stock muffler. Now I got a 2.5 inch setup with x pipe to two 2.5 inch shorty mufflers by porter. She sounds great, not too loud not too quiet. Unless I let her rip at full throttle.
Great muffler
Great quality contruction and cant beat the sound when paired with the freedom flow resonators
Highly recommend these!!! Sound great.
I have been looking for a muffler that gave my roadster the finishing touch and these are them! Deep rumble and the craftsmanship is amazing! Probably going to run them on my other projects. USA!
