01-04 6.6L GM Duramax LB7 DFuser Passenger Side Up Pipe With Gaskets

These stainless steel up-pipes for the 2001-2004 6.6L LB7 Duramax engine are a great upgrade over the stock up-pipes. The mandrel-bent up-pipes flow better than the factory-installed pipes, and they are also less likely to crack and cause restrictions or power-robbing pre-turbo exhaust leaks. The stainless steel up-pipes are a perfect addition to any high-performance down pipe or exhaust manifold purchase.
