Porter High Flow Muffler
Body Length- 20" Overall Length- 26"
Porter’s High Flow Muffler has the same sound-deadening feature as our original standard 3” muffler but is less restrictive. Same sound but with more power!
This muffler utilizes our aluminized steel 5” diameter body so please make sure you have sufficient under-chassis clearance.
Our mufflers are designed to create a slip fit lap joint with your mating exhaust tubing. We suggest welding this joint instead of using band clamps as it will perform better over the length of the muffler and create an air tight seal.

Customer Reviews
3” truck muffler ended up being being a great choice for a good low rumble without being too loud. No drone and sounds great under a load while driving. I was skeptical of trying on a newer truck but turned out great as a custom cat back with a 90 degree turndown.
Thank you Scott for the 5 star review!
I put a pair of the polished stainless 3 inch mufflers on my 2006 gto lsx 454. They helped quiet it down and sound great !! The quality and appearance are outstanding .
thank you for taking your time to leave this review!
I had the 3" truck muffler installed on my 96 F150 with the 5.8 engine. I installed a high flow y pipe that has a 3" outlet to a 3" in/out high flow cat. After the muffler I have dual 2 1/4" pipes out the back. It is very mellow at idle and while cruising, but nail the throttle and man does that truck sound mean! I also have dual exhaust on my 63 Cadillac and am using 2" in/out Porter's. I love the sound at all speeds but she really talks when I open all 4 barrels! Hands down, Porter Muffles are the best muffler you can buy, and the way they are constructed, probably the last set of mufflers you will ever purchase for your ride.
