DIAMOND EYE 221005 EXHAUST PIPE 4 INCH SECOND SECTION SINGLE EXIT SYSTEM FOR 94–2007.5 24V DODGE CUMMINS EXHAUST TAIL PIPE

DIAMOND EYE 221005 is the 4.0" second-section tailpipe for single side exit Diamond Eye systems on 1994–early 2007 Dodge Ram 2500/3500 5.9L Cummins. It mates to first-section tailpipe 221004 and exits behind the right-rear tire for clean routing and OE-style clearance.

Why It’s Better

• Mandrel-bent 4" tubing for reduced backpressure and lower EGTs.
• Aluminized steel for durability and value in daily-driven and work-truck builds.
• Direct-fit geometry to Diamond Eye 4" single exit systems for 2nd-gen/early 3rd-gen Ram.

FAQ: WILL THIS FIT MY TRUCK?

Yes—if you have a 1994–early 2007 Dodge Ram 2500/3500 5.9L Cummins running a Diamond Eye 4" single side-exit system, this is the correct second tailpipe section that slips into first section 221004. Always confirm your system layout before ordering.

FAQ: WHAT DOES “SECOND SECTION” MEAN?

This pipe is the rear tailpipe piece. It connects to the first tailpipe section (221004) and positions the outlet behind the passenger-side rear tire.

FAQ: WHAT CLAMPS DO I NEED?

Most installs use a standard 4" U-bolt clamp at the 221004/221005 joint (see Diamond Eye 444000). Verify your kit contents.
