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

This kit from Diamond Eye Performance gives you a 4-inch stainless steel replacement pipe designed to fit your 2001-2005 Chevrolet Silverado 2500 HD or 3500, or its GMC Sierra counterpart, equipped with the 6.6L Duramax diesel engine. It's a direct replacement for the factory muffler section, allowing you to customize your exhaust system's sound and flow. This part is constructed from 409 stainless steel, which offers good resistance to corrosion and is well-suited for exhaust applications.

Diamond Eye Performance uses CNC mandrel bending machines to create their exhaust components. This process ensures consistent tube diameter throughout the bend, which helps maintain smooth exhaust flow. The 4-inch diameter is a popular choice for Duramax owners looking to improve exhaust efficiency over the stock system. This replacement pipe is designed to fit all cab and bed lengths for the specified models, making installation more straightforward.

When installing this replacement pipe, you'll be working with stainless steel, which is known for its durability. This part is intended to replace the muffler section, so you'll want to consider what sound profile you're aiming for with your exhaust system. Diamond Eye maintains a large inventory and uses efficient shipping methods to get parts out quickly.
