DIAMOND EYE 362005 EXHAUST PIPE 4 INCH 01–EARLY 07 SILVERADO/SIERRA 2500/3500 DIESEL FIRST SECTION PASS STAINLESS EXHAUST TAIL PIPE

DIAMOND EYE 362005 is a 4.0" T409 stainless first-section passenger-side tail pipe built for 2001–early 2007 Chevy Silverado / GMC Sierra 2500/3500 6.6L Duramax (Classic body). Mandrel-bent tubing maintains flow, trims backpressure, and pairs cleanly with OE-style hangers and downstream sections for a durable, leak-free fit.

FAQ: WILL THIS FIT MY DURAMAX?

Yes—if you have a 2001–early 2007 (LB7/LLY/LBZ Classic) Silverado or Sierra 2500/3500 6.6L Duramax and need the first-section passenger-side tail pipe, this is the stainless version. Always confirm cab/bed configuration and that you’re replacing the first section on the passenger side.

FAQ: IS THIS STAINLESS OR ALUMINIZED?

This part is T409 stainless steel. If you prefer steel/aluminized options for cost-sensitive builds, see the Diamond Eye steel cross-references below.

FAQ: WHAT ELSE DO I NEED?

Re-use your existing clamps/hangers if in good condition, or add new Diamond Eye hardware/flanges as needed. This pipe mates with corresponding second-section and system components listed below.
