2015.5-2016 Duramax 3" Downpipe (GM8428)

MBRP Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.

The MBRP GM8428 3" Downpipe helps your 2015-2016 6.6L LML breath by increasing the exhaust flow off your turbocharger. Removing the restrictions caused by your OEM downpipe - the MBRP replacement will lower your EGTs and increase performance. The install process is as simple as it gets from the precision bending that you'd expect from an MBRP kit.
