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.

Dual shorties on Rocket 88

I’m pumped to have the true steel packed old school original mufflers for my ‘52 Super 88. My vintage custom street-racer look now has the dual exhaust sound to go with the Rocket V8 engine.

Thank you so much for your review, Daniel! We're thrilled to hear that our Porter's Shorty Mufflers were the perfect addition to your vintage custom street-racer.

Replaced my slp loudmouth 2 with a porter shortie on my catless 5

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.

Thank you for taking the time to leave us a review! We're glad to hear that our Porter Shorty Mufflers were able to improve the quality of your V8 exhaust note and reduce drone. We appreciate your feedback and support. Happy driving!

Best Sound

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!
