The Sinister Diesel stainless steel up-pipes for 2001-2016 6.6L LB7, LLY, LBZ, and LML Duramax engines are a great upgrade over the stock up-pipes. The Sinister Diesel mandrel-bent up-pipes flow better than the factory-installed pipes, they are also less likely to crack and cause restrictions or power-robbing pre-turbo exhaust leaks. The Sinister Diesel stainless steel up-pipes are a perfect addition to any high-performance down pipe or exhaust manifold purchase.
