CORSA Performance Sport 4.0in Muffler Upgrade Kit

For Dodge RAM Cummins & Ford PowerStroke Trucks

The CORSA Performance Sport 4.0in Muffler Upgrade Kit is engineered to improve exhaust tone while mitigating the most common drone-inducing frequencies found in diesel exhaust systems. Designed as a direct muffler replacement, this kit delivers a deeper, more aggressive sound without sacrificing highway comfort.

Constructed from premium 304 stainless steel, the round-body muffler is built for long-term durability under extreme diesel exhaust temperatures and harsh operating conditions. Featuring a 4.0-inch center inlet and outlet with expanded ends and included clamps, this muffler is designed for straightforward installation on compatible 4.0-inch exhaust systems.

CORSA Performance diesel mufflers are acoustically tuned to target and reduce drone-causing frequencies. While overall drone reduction can vary based on muffler placement and vehicle modifications, this upgrade offers a proven improvement in sound quality over restrictive factory mufflers.
