The OEM cast iron flanges rust / corrode and eventually split causing exhaust leaks
A common fault on E46 M3 models is failure of the exhaust flanges caused by rust / corrosion of this part. Four flanges are used to clamp together and seal the intermediate pipe to the rear muffler / backbox. These are constructed of cast iron (despite being fitted to a stainless steel exhaust) and inevitably deteriorate and split. These parts are integral to the intermediate pipe and rear muffler and are not available separately from BMW.
Our high quality stainless steel flange kit splits around the exhaust pipes, allowing you to replace the flanges without having to remove the exhaust. Simply grind off the old flanges (often they will just fall apart) slot our new flanges in to place and fasten.
Our clamps are designed to be very simple to fit with no grinding usually required, a straight fit unlike many others on the market. No welding required, our flanges are designed for the life of the vehicle and can be removed in future and reinstalled with no hassle.
