Big Gun 12in x 2in EXO Core

Big Gun is known for making powersports exhaust components, and this 12-inch EXO Core insert is a good example of their focus on performance parts. This specific core is designed to be a direct replacement for the internal muffler core in their EXO and EXO Stainless Series mufflers. If you're looking to refresh the sound or performance of your existing Big Gun muffler, this part is what you need.

The core itself is constructed from 304 stainless steel, which is a solid choice for exhaust components because it holds up well to heat and corrosion. It features a 2-inch outer diameter and a total length of 12 inches, and it's built with sound wave altering technology to help tune the exhaust note. To make sure you get the right size, measure the length of your muffler canister, not including the inlet cone piece.
