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.

Replaced my slp loudmouth 2 with a porter shortie on my catless 5.3 So much better quality v8 exhaust note with little to none drone. It's a little bit quieter but is totally worth it since I don't have to put up with that horrible drone.
I'm very impressed with you. Shipping to Germany was perfect. Thanks to the team...see you next time. Best regards, Steven
Very much satisfied. Great products.
Thank you!!
I replaced another major brand shorty muffler with a Porter Shorty. Absolutely love the sound. Made the old Chevy sound like it should!
Thank you Jacob!
Got rid of the annoying raspiness my car originally had and made it have the perfect tone. Also is quiet at idle but you hear it when on the throttle just enough. I was very impressed. I am recommending this company from now on for mufflers.
Thank you for this detailed 5 star review!
