5" Tall x 8" wide x 24" long. With a single, perforated core that runs from the inlet to the outlet, this muffler vastly improves exhaust flow. Stainless steel mesh and acoustic fiber insulate the core and deliver a smooth, deep tone.

This OEM-style muffler has two separate, perforated cores that enhance airflow. Both cores run through three chambers that contain tuning gates, called "baffles," which help to cancel out sound waves and reduce exhaust noise.

3" Inlet/outlet; 4" diameter x 22" long. Achieve the classic glass pack sound without the burnout common to fiberglass-packed mufflers. Basalt rock wool surrounds a straight-through core, which enhances engine performance.

5" Tall x 8" wide x 20" long. With a single, perforated core that runs from the inlet to the outlet, this muffler vastly improves exhaust flow. Stainless steel mesh and acoustic fiber insulate the core and deliver a smooth, deep tone.

Featuring a single, perforated core that runs from the inlet to the outlet, this muffler vastly improves exhaust flow, thereby increasing engine performance. Stainless steel mesh and acoustic fiber insulate the core and deliver a smooth, deep tone.

Two perforated cores in Tru-X mufflers intersect in the middle to pull gases, rather than push them, through the exhaust system. This suction effect diminishes the decibel level and boosts mid-range horsepower, improving overall engine performance.

Featuring a single, perforated core larger than standard, straight-through mufflers, this muffler boosts engine performance on racing vehicles. An external sound dampener reduces exhaust noise to accommodate decibel-level regulations at racetracks.
