DONGMAO BMW 335i E90 E92 N54N55 3.T (2007-2015) Performance Muffler

Overview

2007 BMW 335i E90 E92 N54N55 3.T 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.
