	=== Replacing rusted flanges with split flanges ===		=== Replacing rusted flanges with split flanges ===

			The OE cast iron flanges corrode and eventually split causing exhaust leaks. 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 exhaust and are not available separately. The only option until now has been to buy a new exhaust at vast expense. Or to buy new flanges, cut them up, fit and re-weld them - a tricky job. None of these are an ideal solution to this common fault.

	On [[M112]] and [[M113]] exhausts there are 3 factory mounted ~~flanges~~: two in the middle, one in the rear.		On [[M112]] and [[M113]] exhausts there are 3 factory mounted flange connections: two in the front (middle of the car) and one in the rear.
	Once they get rusted, the only option is to cut them off and install split flanges instead.		Once they get rusted, the only option is to cut them off and install split flanges instead.

			Required parts:
			* Sealing ring (A2024920281) x2
			* Graphite sealing ring (A1269970041)
			* Split flange for pipe diameter of 60mm (HJS 82007060) x2
			* Split flange for pipe diamater of 55mm (HJS 82007055)

			The diameter of [[M112]] and [[M113]] exhaust pipes is 55mm except for the rear pipe of the right front flange connection, which has 60mm diamater (55mm pipe slips into the 60mm pipe).

			Even though most of the pipes are 55mm, since the diameter of 55mm pipes increases closer to the connection, it might be required to install 60mm split flange instead (at least on one side of the connection) or use longer bolts (not included in split flange set).

			The principle of applying split flanges on the front flange W220 exhaust connections is very similar as on BMW E46 exhaust:
