11-16 Duramax LML Stainless Passenger Side Up Pipe and Down Pipe Bundle - WCFAB

We have found these two are usually purchased together so we created a listed to buy both at the same time! Both the LB7 style up pipe and LML down pipe from WCFAB.
 
Replace the lightweight, leak-prone passenger side OEM up pipe with this heavy-duty 11 gauge 2" Stainless up pipe. HD Stainless Bellow that will not crack and leak like OEM. Increase Turbo spool up and decrease EGTs. This up pipe is built to clear a conventional downpipe behind the engine in single turbo applications. (it can still be used with twin turbo also) Compatible with factory exhaust manifold only.
 
Fits 2001-2016 Duramax in a racing and sled pulling application.
 
Optional:
Full set of 6 ARP 12PT up pipe bolts VIEW HERE
Down pipe plugs for the 3 ports VIEW HERE
 
***Designed for use with WCFab down pipe. OEM and another aftermarket downpipes may require additional modifications***
 
Unsure which down pipe to get? Here's a general reference guide but you have to physically look on any 2015.
 
11-14 vband
2015 can be either
2016 3 bolt
 
For the 2015 Duramax LML, you will need look through the passenger wheel well at the connection where the down pipe meets the exhaust to tell which down pipe you have and will need.
 
2011 - early 2015 will be a vband clamp holding them together. This is the "vband" option.
2015.5-2016 will have 3 bolts holding a ring up against the exhaust. You will see 3 nuts. This is a "3 bolt" option.
