XR-1 Sportsman Racing Mufflers

Straight-through tube design provides both awesome low-end torque, as well as top-end horsepower. These mufflers are 100% Stainless Steel unlike many competitors!

Oval Muffler Features:
Lightest, most compact, and highest flowing racing muffler in its class. The choice of winners from top Mustang drag racers to Baja Off-Road trophy trucks.

Round Muffler Features:
This Muffler is 5 inches in diameter and 15 inches long. Designed for door car/ roadster applications that require a compact round muffler.

Offset Muffler Features:
The inlet/outlet are offset to the same side of the muffler, to accommodate transmission and frame rail interference on some applications. Ideal for stock chassis vehicles.
