Weistec M157 Downpipes & Exhaust, G63

Weistec Engineering offers True Downpipes for M157 AMG and M278 powered vehicles. Replacing the small and restrictive factory downpipes delivers significant gains in power, throttle response, and exhaust tone.

Engineered and designed with the most sophisticated Computer Aided Design tools, excellent fitment and the highest performance possible are guaranteed. Each downpipe has a specially designed CNC machined turbo outlet flange, transitioning into a 3 inch pipe and low profile V-Band flanges to mate with our Midpipes.

Branded Weistec stainless steel heat shields are also included to block rising heat from the exhaust manifold.

Our Biturbo Midpipes bolt to the Downpipes using a low profile V-Band flange and transition to the factory axle-back. Each Mid-pipe has stainless steel brackets for solid bolt-in fitment and is made of 3 inch stainless steel piping creating a very high flowing quality exhaust system.

Complete exhaust system includes Downpipes, Midpipes, Heat Shields, Gaskets, and Hardware.
