The GMC Sierra 3500 HD Performance Exhaust by Wehrli is the ultimate upgrade for your 2011-2016 Duramax diesel truck. This heavy-duty exhaust system is crafted from 11-gauge stainless steel, providing exceptional durability and improved exhaust flow for optimized performance.

Designed to replace the lightweight, leak-prone OEM exhaust components, the Wehrli Performance Exhaust Kit features 2-inch stainless steel up pipes with HD stainless bellows. These high-quality materials ensure longevity and prevent cracking and leaking, which are common issues with standard parts. Ideal for hard-working, heavy towing trucks or high-performance applications, this exhaust system enhances turbo spool-up and reduces exhaust gas temperatures (EGTs).

Features

• 11-gauge stainless steel construction
• Fully TIG welded for maximum strength
• Included up pipe and EGR cooler gaskets (5 pieces)
• Compatible with OEM & WCFab turbo downpipes
• Ductile iron cast EGR connection with EGT sensor port

This exhaust system is a perfect match for OEM style exhaust manifolds and can seamlessly integrate with larger, upgraded turbochargers.
