Performance Mufflers - 2-1/4 Inch Inlet Diameter

4" Tall x 9" 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.

2-1/4" Inlet/outlet; 3-1/2" diameter x 26" 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.

Recommended for customized street cars, this muffler features a tuning tube that runs from inlet to tip, maximizing exhaust flow and increasing engine performance. The exhaust exits through a fully polished tip, yielding 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.

2-1/4" Inlet/outlet; 3-1/2" diameter x 30" 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.

Recommended for customized street cars, this muffler features a tuning tube that runs from inlet to tip, maximizing exhaust flow and increasing engine performance. The exhaust exits through two fully polished tips, yielding a smooth, deep tone.

Featuring a single perforated core larger than most straight-through cores, this muffler boosts engine performance on racing vehicles by maximizing exhaust flow. Mesh and acoustic fiber reduce the decibel level, and it includes fully a polished tip.
