Porter’s Shorty "Small Core" Mufflers

Body Length- 14" Overall Length- 20"

Porter Mufflers "Small Core" mufflers are exactly the same as our Shorty Porter Muffler but

is designed specifically for lower horsepower applications, while still running your 2.5” exhaust to give you that quality Porter Muffler sound.

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.

What makes the small core special? The small core has the same core I.D. as the 3.5” body sizes; 1.375” --- vs. 2” like all of the other 4” body sizes
