DONGMAO BMW M3 M4 F80 F82 F83 S55 3.0T (2014-2019) Ss304 Mid Pipe Resonator

Overview

2014 BMW M3 M4 F80 F82 F83 S55 3.0T Ss304 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
