2001-2016 Duramax 6.6L Dirty Passenger Side Up-Pipe (DUR-EXH-A020)
Fix the exhaust leak and restore your boost levels. Whether you’ve blown out the weak factory bellow on your passenger side up-pipe or you're finishing an EGR service on your 2001–2016 Duramax, the Dirty Passenger Side Up-Pipe is the definitive solution. We’ve seen enough factory units fail under pressure to know that a "stock replacement" isn't enough; you need something built for the long haul.
This up-pipe is constructed from heavy-duty mandrel-bent stainless steel tubing and features precision CNC laser-cut flanges for a perfect, leak-free seal against the manifold and turbo. We’ve integrated high-performance bellows that are designed to handle the extreme heat cycles and vibration of a high-output diesel engine without cracking. This is Canadian-made hardware designed to outlast the truck.
Note: Required custom tuning for 2004.5–2016 models. For Off-Road and Competition Use Only.
