Diamond Eye Performance
Diamond Eye 4" Single Tailpipe 1st Section (Aluminized) for 2001-2007.5 Chevy/GMC 2500/3500 (6.6L) 321051
$123.29
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2001-2007.5 Chevy and GMC 2500/3500 trucks (6.6L).
This Diamond Eye 4-inch single tailpipe first section is engineered specifically for off-road configurations, serving as a critical component in cat-back or downpipe-back exhaust setups. Constructed from durable aluminized steel, this pipe is CNC mandrel-bent to ensure a consistent diameter throughout the bend, minimizing backpressure and optimizing exhaust flow for the Duramax diesel engine. This section replaces or completes the first part of the tailpipe assembly in Diamond Eye performance exhaust systems.
- Material: CNC mandrel-bent 4-inch aluminized steel tubing for corrosion resistance and flow efficiency.
- System Context: Designed for use with single-exit off-road cat-back or downpipe-back kits.
- Bending: Precision mandrel bends maintain a 4" OD to prevent restriction.
- Compatibility: Direct-fit component for 2001-2007.5 GM 2500 and 3500 HD chassis.
- Manufacturer Part Number: 321051
