OEM exhaust pipe/muffler (cat-back) from my 2005 R-53 MCS is available for $275, as is.
It is almost new quality since I removed it after only 1000 miles to put an after market system on.
It is one piece from the cat flange to the chrome tips. No hangers, just the pipe/exhaust system.
I am in Annapolis area and will discuss purchase/pick up options if interested.
