If worse comes to worse a machine shop should be able to fabricate you an exhaust. I wouldn't imagine it would be very expensive, especially if you didn't mind it being a little noisy and leave mufflers off. Just straight pipes and a couple of bends. I would look for a good machine shop around you just for grins at least and bring the exhuast in to see if they can do it and get an estimate.
Did he have a little scorpion stealth compartment built or some shit? Might be new shoes time, I'd be gun shy with that pair forever after that.
I'll go ahead and just turn my pants over now. Wait...nevermind. The struggle's the best part.
