Diamond Eye KIT 4in Catback Single SS CHEVY/GMC 6.6L 2500/3500 01-05

This is the Diamond Eye 4-inch stainless steel cat-back exhaust system for your 2001-2005 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD, and 3500 models with the 6.6L Duramax diesel engine. This kit replaces your factory exhaust from the catalytic converter back, offering a more direct path for exhaust gases to exit the vehicle. This can lead to a more aggressive exhaust tone and potentially improved performance by reducing backpressure.

Diamond Eye Performance uses CNC mandrel bending to create smooth, consistent bends in the tubing. This process helps maintain the pipe's diameter throughout the bend, which is crucial for efficient exhaust flow. The system is constructed from 409 stainless steel, a well-built material known for its resistance to corrosion, especially in areas exposed to road salt and moisture. This means the exhaust system should hold up well over time, even in challenging conditions. The single muffler design is intended to provide a distinct exhaust note without being overly intrusive.

This cat-back system is designed to fit all cab and bed lengths for the specified model years, simplifying the selection process. The kit includes all the necessary components for installation, allowing for a straightforward bolt-on upgrade from your stock exhaust. If you're looking to enhance the sound and performance of your Duramax truck, this stainless steel cat-back system from Diamond Eye is a solid option.
