ARL-2605 Street / Performance Muffler

The ARL-2605 Street / Performance Muffler uses a larger 6-inch body to create a deeper, more controlled exhaust note while maintaining excellent performance capability.

Compared with the smaller 2603 and 2604, the 2605 provides greater sound suppression, increased depth, and reduced harshness while maintaining strong exhaust flow. It is one of the most versatile mufflers in the ARL lineup for powerful street-driven vehicles.

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