Description
The MBRP GM8424 3″ Downpipe helps your 2004.5-2010 6.6L LLY/LBZ/LMM breathe by increasing the exhaust flow that comes off your turbocharger. This system features full 16-gauge mandrel-bent tubing for maximum flow and an extremely high-temperature ceramic coating. By removing the restrictive OEM downpipe and replacing it with a free-flowing MBRP downpipe, you will deepen the sound of your 6.6L, lower 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!
