Replacement Exhaust Flange Brackets Repair Fix Kit For M Performance M3 E46


Upon inspection, you will be able to see that the flanges of the BMW 3 Series E46 M3 (07/1999 鈥?08/2006) are rusted, corroded, and often split or starting to. This can cause the exhaust to blow, leading to MOT failure or advisories. In some cases, the exhaust may need to be removed for an upgrade or subframe repair, requiring the original flanges to be grinded and replaced.

The OEM cast iron flanges used to clamp together and seal the intermediate pipe to the rear muffler/backbox are prone to rust, corrosion, and eventual splitting. These flanges are not available separately from BMW, forcing owners to either purchase a new center section at a high cost or go through the complicated process of cutting, fitting, and welding new flanges. Neither of these options is ideal for this common fault.
