Wehrli Down Pipe (3 Bolt Flange) 3in. for 2015.5-2016 Duramax LML Stainless Stainless 100705

The Wehrli 100705 3-inch Stainless Down Pipe is a direct replacement for the restrictive factory crushed unit on 2015.5-2016 LML Duramax 6.6L trucks. This downpipe provides a smooth, unrestricted path for exhaust gases, resulting in faster turbo spool-up, cooler exhaust temperatures, and stronger throttle response. It is built from precision-formed 3-inch stainless steel for long-term durability and corrosion resistance. The pipe features a 3-bolt flange that mates directly to the factory turbo or compatible aftermarket drop-in units. All necessary hardware, including heat wrap and clamps, is included for installation and thermal protection. Professional installation is recommended.
