BMW M3 E9x Powerflex Uprated Rear Exhaust Mount Bush

Designed to replace the original rear exhaust mount bush fitted to the BMW M3 E9x, this Powerflex polyurethane bushing is 15% stiffer to provide improved support for the exhaust system. Stronger and more durable than the original rubber mount, it fits without modification and can be used with both the OEM exhaust system and aftermarket sports exhausts that retain the original mounting points.
