DONGMAO BMW E90 E91 E92 E93 335i 3.0T N55 (2011-2013) Stainless Steel Cat-Back Muffler

Overview

BMW E90 E91 E92 E93 335i 3.0T N55 11-13 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

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