DONGMAO Performance Mid Pipe BMW M340i G20 3.0t (2019) OPF

Overview

2019 BMW built by Dongmao as a direct-fit exhaust system. Every unit is assembled on a platform-specific jig, so flange angles, hanger positions and tip alignment repeat from the first unit of a batch to the last.

Tube work is T304 Stainless with mandrel bends throughout. Welds are back-purged TIG, inside and outside, then checked for penetration before the part moves to finishing.

What is included

• Pipe section with flanges and heatshield where specified
• Gaskets and fitting hardware
• Export carton with foam protection
