Description
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.
