High Performance Mufflers"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."
High-Performance Steel Pack Mufflers
Offering high-quality mufflers, exhaust kits, and accessories that are proudly made in the USA.
Choose between 16-gauge seamless aluminized steel or 304-grade stainless steel bodies for your Porter Muffler. Both styles feature 12-gauge welded steel end caps and a spiral steel core.
Our spiral cores are wrapped with American-made materials, proudly manufactured in Wisconsin. Experience the dynamic sound of Porter Mufflers – the louder you press the 'go pedal,' the more intense the sound. Release the gas, and the sound mellows back out, providing a comfortable and quiet ride.
No Drone Feature: Cruise in Comfort
Thanks to the heavy construction of Porter Mufflers, you can enjoy a 'no drone' feature that guarantees comfortable cruising for years to come. Invest in a high-quality, American-made exhaust system that perfectly balances performance and comfort.
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.
