Product Description




Welder working on M139 Downpipe

FABRICATED IN HOUSE

Weistec Engineering offers the M139 Downpipe for Mercedes Benz M139-equipped vehicles. The downpipe was designed with the most sophisticated Computer Aided Design tools to ensure excellent fitment. The downpipe features 3.5-inch diameter piping and a laser-cut precision bracket to mate with factory mounting points, giving this system a perfect fit.



FUNCTIONAL

Our downpipes feature CNC Machined 304 stainless steel turbine flanges to mate with the turbo perfectly using the OEM clamp. The M139 Downpipe mates to the rest of the exhaust using an OEM-style adapter for a simple bolt-in installation.

*Product may not be emissions compliant. Check local laws prior to installation.
