ok ok i know there are a dozen threads about ARD vs APR vs stock.

one of my pipes was damaged in an accident, and i'm trying to rebuild the car. i cannot find OEM bi pipes anywhere, so i'm trying to decide between ARD and APR. the car has stock k03's with around 10k on them. the car has numerous other upgrades from chip to intake to exhaust, including divs and intercoolers. i'm thinking the ARD set because of the smooth air flow, and the stock tbb has proven itself in race applications up to 35psi of boost. plus i have heard rumors that the APR set heatsoaks badly..

so, does anybody know where i can pick up the OEM bi pipe cheaply?
failing that, does anybody see a reason why i shouldn't go with the ARD set?
