A shop won't blatantly remove a CAT, dead or alive, to install a "test" pipe,
it's an emissions tampering violation... The exception is if you trailer the car
in and convince them it's a track only car. If you walk into a shop with the
dimensions and/or a PVC mock up and a sample of the flanges, a good shop should
be able to build you want you want for probably 10% of $1500. IMHO there is no
justification for $1500 for a downpipe!
