Part #: 8004000

Overview

The CORSA Performance Sport Sound Level Muffler Upgrade Kit is designed to enhance the exhaust note of your Chevrolet or GMC Duramax diesel truck. Crafted for enthusiasts who seek a more aggressive sound without excessive drone, this kit provides a balanced combination of performance and acoustics. Whether you're a daily driver or a weekend warrior, you'll appreciate the deeper, sportier exhaust tone that elevates your vehicle's presence on the road.

Construction & Design

The CORSA Sport Sound Level Muffler Upgrade Kit is meticulously engineered with high-grade materials and advanced manufacturing techniques. The stainless steel case and internal components are TIG-welded for strength and precision.

The muffler's internal chamber design is tuned to cancel out drone frequencies, ensuring a quieter cabin during highway cruising while still delivering an aggressive exhaust note when under acceleration. Its durable construction and corrosion-resistant materials make it suitable for the demanding conditions of diesel trucks, including off-road adventures and heavy-duty use.
