Diamond Eye K5126S-RP 5" Cat-Back Single Exhaust System 409 Stainless Steel

The Diamond Eye K5126S-RP is a 5-inch single cat-back exhaust system engineered specifically for 2006 to early 2007 Chevrolet and GMC 2500/3500 trucks equipped with the 6.6L Duramax diesel engine. This performance exhaust system is designed to fit all cab and bed length configurations, providing a universal solution for heavy-duty truck owners seeking enhanced exhaust flow and performance.

Key Features:

• 409 Stainless Steel Construction: Provides superior corrosion resistance and durability compared to aluminized steel, with an attractive finish that lasts
• 5-Inch Mandrel-Bent Tubing: CNC mandrel-bent pipes maintain consistent diameter throughout bends for maximum exhaust flow and reduced backpressure
• Muffler Replacement Pipe Included: This kit ships with an eliminator pipe instead of a muffler, delivering aggressive exhaust tone and uninhibited sound for those who prefer straight-pipe performance
• Complete Cat-Back System: Runs from the catalytic converter back to the rear exit, includes all necessary pipes, clamps, and integrated hangers for straightforward installation
• Universal Fitment: Accommodates all cab styles (Regular, Extended, Crew) and bed lengths (Short, Long) as well as dually configurations

This exhaust system is designed to reduce exhaust gas temperatures (EGTs), improve throttle response, and deliver an aggressive diesel sound. The mandrel-bent construction ensures smooth airflow without the restrictions found in factory crush-bent exhaust systems. Installation includes all necessary mounting hardware and clamps, with some hangers featuring integrated clamps for added convenience.

Note: This system does not include a muffler and ships with a straight pipe eliminator for maximum flow. Exhaust tips are sold separately. Not legal for sale or use in California, Colorado, or New York on pollution-controlled vehicles.
