The First Aftermarket Muffler.

That's right. The Porter Brothers nailed it when they decided to create a better muffler than what was being sold on the vehicles. While some say "they don't make em' like they used to" we still do and always will. You can't beat perfection and you certainly can't beat the Porter Muffler sound.

Porter Mufflers Reviews

Porters sound great, especially with no tail pipes. Definitely that back to the fifties kinda sound.


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!

We've used many of these mufflers over the years. They look great and sound great. Perfect for early cars and trucks that retain their vintage power plants.... in my opinion. 


Can't beat Porters on a Flathead Ford V8 ! 


That sound... that pitch .. that tone .. whatever you want to call it... is perfect!
