Exhaust Up-Pipe for 2001-2016 6.6L Chevrolet Chevy GMC Duramax LB7 LLY LBZ LMM LML | SPELAB

Up-pipes and down-pipes – what do they do?

Up-pipe is a piping that connects the exhaust manifold with the turbo. Exhaust gases enter the turbo from the up-pipe. Down-pipe is a piping that connects the turbo with the rest of the exhaust pipe. Exhaust gases leave the turbo from the down-pipe. For those looking to enhance their Duramax's performance, consider our LML delete kit and Duramax delete kit for optimal results.
