BD Diesel 2001-2004 Chevy Duramax LB7 6.6L Up-Pipe Only for Passenger Side

When you're working on your 2001-2004 Chevy Silverado 2500 HD with the 6.6L Duramax LB7 engine, you'll find that the factory exhaust up-pipes, which connect the exhaust manifold to the turbo, are a common spot for leaks. This BD Diesel up-pipe is specifically for the passenger side and is designed to be a more durable replacement for those deteriorating stock pipes.

This up-pipe is constructed from 304L 2-inch stainless steel tubing, which resists corrosion and helps maintain exhaust gas energy. It features precision-cast stainless steel mounting flanges to prevent blowouts and ensure it fits right. The internally shielded expansion bellows are built to handle the heat and movement, offering a longer service life than the original parts. Smooth mandrel bends are used to improve exhaust gas flow without compromising the tubing's inner diameter. Keep in mind that this up-pipe requires an aftermarket downpipe and will not fit with the OE downpipe.

This part is a solid option for replacing leaky up-pipes, especially if you're already doing other engine or transmission work. It's designed to be a direct replacement for the passenger side up-pipe on your Duramax LB7.
