The Porter “Shorty Offset” Mufflers are for those who are replacing “turbo” mufflers with offset inlets and/or outlets that were commonly found on the 1960’s muscle-cars. They feature a 14″ body length and 20″ overall length so they will easily fit within the muffler pockets of cars originally equipped with oval mufflers while maintaining the original exhaust pipe routing. The offset Porter Muffler is offered in two options for your offset needs, 11 degrees and 17 degrees. The offset Porter Muffler is handmade using heavy duty 16 gauge aluminized tubing. The stainless steel Porter Muffler is handmade using heavy duty 16 gauge, highly polished aircraft grade, 304 stainless tubing. Our uniquely designed interior chamber is fitted with a gapped steel spring 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.
