ARL-2604 Street / Performance Muffler

The ARL-2604 Street / Performance Muffler bridges the gap between the compact ARL-2603 and the larger ARL-2605. Its 5-inch body provides additional internal volume for improved depth and sound refinement while retaining the aggressive character expected from a performance exhaust.

The result is a muffler that remains loud and authoritative without being as sharp or raw as the ARL-2603.

Designed in-house using CAD, tested in real-world applications, and manufactured in-house by Aronson Racing Lab.
