About Porter Mufflers High Performance Mufflers

Our History…

Porter Mufflers was started in 1931 by the Porter brothers in Los Angeles and for generations the same basic design has proven itself to be the best performance muffler available. When you have a product that’s just about perfect the worst thing you can do is change it so we have never felt the need to, “reinvent the wheel.” Ownership of the company has changed, materials advances have been incorporated, and the vehicles they have been used on have definitely changed but our bottom-line has always been quality and performance.

The Giovannoni Speed Shop, circa 1955, was quite famous for their cams and their ads

It doesn’t matter if you’re driving a flat-head powered ’32 Deuce Coupe, a big-block musclecar, a turbo-powered import, a high-tech late-model pony car, or a trail-blazing 4×4 no other muffler will free-up more horsepower than a Porter Muffler. We have been the performance standard by which other mufflers are judged for over 80 years!

Performance is also about longevity and Porter Mufflers are the most durable performance muffler you can install on a performance vehicle. There are more than a few that were installed in the 50’s and 60’s that are still being used to this day and some Porter Muffler owners will remove the mufflers when they sell their ride for use on their next car!

Porter Mufflers installed in 1968, still in use today!

"I have a 1951 CJ3A Jeep which I have owned since 1968. Not too long after I bought it someone told me about Porter Mufflers and I had them [the actual Porter Brothers] install a dual exhaust system with their mufflers on the Jeep. To say they performed well is an understatement. My Jeep has been through the world-famous Rubicon Jeep trail at least 100 times since and has also been to Baja twice and to Moab, Utah to challenge the sandstone cliffs there. We finally moved from California in 1997 to the southern Oregon coast and now the mufflers are accosted by the sand and the salty Pacific Ocean water at the beach. Still, they continue to perform!"
