Description

The Wehrli 100122 is a 3" downpipe designed for S300 turbos with an HX40 style exhaust outlet flange. It is compatible with LLY/LBZ/LMM/LML 6.6L Duramax engines. The turbo pedestal height must be between 5-6" tall for proper fitment. The lower flange of the downpipe mates to the factory exhaust system flange for easy installation with the OEM V-band clamp. This part supersedes WCF100238.
