The MBRP GM8427 3" Downpipe helps your 2011-2015 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.
