SPOOLOGIC Heavy Duty 304SS High-Flow Bellowed Up-Pipe Kit

The SPOOLOGIC 304 Stainless Steel Bellowed Up-Pipe Kit SL-510-024 replaces both exhaust up-pipes on 2007.5–2010 Chevrolet Silverado 2500 3500 and GMC Sierra 2500 3500 pickups with the 6.6L Duramax LMM engine. Stainless steel tubing and bellowed sections carry exhaust from the manifolds to the turbocharger while accommodating heat-cycle movement.

Features

• 304 stainless steel construction with mandrel-bent main tubing
• Welded mounting flanges and new gaskets seal the manifold and turbocharger connections
• Supplied up-pipe mounting bolts for all four main flange connections

What’s Included

• 1 driver-side 304 stainless steel bellowed up-pipe
• 1 passenger-side 304 stainless steel bellowed up-pipe with EGR connection
• 1 Up-Pipe Gasket Kit SL-310-205 — 2 lower manifold-side gaskets and 2 upper turbo-side gaskets
• 1 up-pipe EGR connection gasket
• 12 up-pipe flange bolts
• 2 washers

Fitment

• 2007.5-2010 Chevrolet Silverado GMC Sierra 2500 3500 6.6L Duramax LMM

For 2007.5–2010 LMM pickups with the original EGR cooler connection and turbocharger location. For 2007 trucks, confirm the new-body LMM configuration. The 2007 Classic LBZ uses a different passenger-side up-pipe and EGR connection. These pipes use the factory manifold connection locations. Verify compatibility before combining them with aftermarket manifolds or a relocated turbocharger.
