Don't bother installing it on a car to try and get free parts. If the car you install it on has already had the trap-ox removed by the dealer, the VIN will show it in the system and they won't do it twice.

Jeremy, I'm pretty sure that the '86/'87 OM603 came with a trap-ox also, which was replaced by a trap-cat in the front pipe after the downpipe.
