Description
XDP has teamed up with MBRP to help produce the missing link in the Duramax Exhaust System. Now Duramax LLY/LBZ/LMM owners have the ability of connecting the turbo and aftermarket down-pipe back exhaust system by removing the restrictive stock pipe pictured below. The MBRP down pipe provides a smoother flow from the turbo resulting in lower EGTs and increased performance. The down pipe is a relatively easy install due to the precision bends that youve come to expect from MBRP.

Was a great fit in place of old stock smashed pipe! Sounds great definitely would recommend. We put one on our work truck and it was the reason I decided to get one as well. Worth the money.

Down pipe is a grate fit needed to bend my dipstick tube alittel to clear it could be cause I put aftermarket up pipes when doing the down pipe

Answer
The MBRP Turbo Outlet 3" Performance Duramax down pipe will work with all stock and aftermarket exhaust system regardless of the size.
Do you reuse the stock turbo heat shield?

Will this work with 4" MBRP front pipe? Lbz

Answer
Yes! An easy rule to follow is that since this replaces your factory downpipe, any exhaust that fits with your factory downpipe will also fit with the MBRP Downpipe.
