Big Gun 15in x 1in 7/8in Race Core

This is the Big Gun 15-inch Race Core, designed as a replacement part for their EVO and ECO Series powersports mufflers. If you're looking to refresh the internals of your existing Big Gun muffler, this core is what you need. It's a straight-through design, meaning it offers minimal restriction for exhaust flow, which is key for performance.

The core itself is made from 304 stainless steel, a well-built material that holds up well against exhaust heat and corrosion. It measures 13-1/4 inches in total length and has a 1-7/8 inch diameter. It's important to measure your old core, as some older mufflers used different diameters on the inlet and end tip sides, and this replacement core requires 1-7/8 inch diameters on both ends.

This race core is intended for use with Big Gun mufflers that have a 15-inch overall body length, not including the removable end tip. It's a straightforward replacement part for those seeking to restore or modify the performance characteristics of their Big Gun exhaust system.
