DONGMAO BMW M3 E90E92E93 4.0l (2009-2013) Cat-Back Muffler X Titanium

Overview

2009 BMW M3 E90E92E93 4.0l 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 Titanium 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

• Complete pipework with muffler and tips as shown
• Clamps, gaskets and mounting hardware
• Export carton with foam protection
