Enhance the performance of your Chevrolet 6.6L LML Duramax engine with the WEHRLI WCF100121 11-15 3" Down Pipe. This top-of-the-line down pipe is designed to replace the restrictive crushed factory down pipe, allowing for improved exhaust flow and increased power output.

Crafted with precision, this down pipe is suitable for use with both factory turbo systems and factory-style drop-in turbos. It is a direct replacement for GM Part Numbers 12643610, 12638304, and 12643214, ensuring a perfect fit and seamless installation.

Featuring a 3" diameter, this down pipe is coated with a high temp black ceramic coating for added durability and heat resistance. The included heat wrap further enhances performance and protects surrounding components from excessive heat exposure.

Please note that for 2015.5 and newer LML models with a 3 bolt flange exhaust system, this down pipe is only compatible when paired with a 2011-2014 style exhaust system that features a v-band connection. Alternatively, you can opt for our 3 Bolt Flange Stainless Down pipe PN: WCF100705 for a suitable fit.
