Darrin, I appreciate the advice. No, I'm in Florida and there are so such restraints for emissions. However the seller does state that the CAT is intact and meets CA standards regardless.
I wound up going with a shop called Mid-West Eurosport in Bensonville right near O'Hare. They specialize in P-Cars and consider themselves a race ready specialist shop. Lot's of interesting projects on their web site and the owner Roy is really nice and sounds super thorough. It's getting inspected today so fingers crossed!
