Wehrli Down Pipe (V-band Style) 3in. for 2011-2015 Duramax LML Black 100121

MIA's Description

The Wehrli 2011-2016 LML Duramax 3" Down Pipe is a performance exhaust upgrade designed to replace the restrictive factory down pipe. It features a full 3-inch diameter for improved exhaust flow and is compatible with factory or factory-style drop-in turbochargers.

This down pipe replaces GM Part Numbers 12643610, 12638304, and 12643214. It utilizes a V-band connection, making it suitable for 2011-2014 style exhaust systems. For 2015.5 and newer LML models with a 3-bolt flange, an alternative down pipe (PN: WCF100705) is required.
