With regard to your OE exhaust system, what I think might be of value is your catalytic converter? Can you tell us how old it is and how many miles? IF it is a true BMW OE cat with low miles, then its probably worth something as a factory replacement is in the $1000 range! Further, OE cats are manufactured in europe and are not available aftermarket. If you want an OE BMW cat the only option is the dealer.

Things like resonator and rear muffler, can be bought OEM as they are supposedly made by Eberspacher. Eberspacher OEM mufflers cost around $250 or so.
