Porter’s “Shorty Offset” Mufflers

The Porter “Shorty Offset” Mufflers are for those replacing “turbo” mufflers with offset inlets and/or outlets 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 initially equipped with oval mufflers while maintaining the original exhaust pipe routing.  The offset Porter Muffler offers 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 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.

Picking The Correct Offset Mufflers– If you are currently using a flat, oval-style turbo muffler and cannot change the existing pipe routing to accommodate the straight Porter Mufflers, we do have “Shorty Offset” mufflers to replace them!
