Tires vs exhaust. exhaust wins first round!

Hey everyone. I have 73 Dodge (Demonized) Dart Sport with a 323 narrowed rear end w/ Cragar 15X10 398's that presently have Mickey Thompson ss N50-15's Indy profiles on it. Just had Header back to chrome tip custom exhaust installed by a local shop and first trip out tires rubbed the tires pretty bad. Is their a series tire that's narrower than Indy Profiles? shop is going to repair and replace for me, but want to know my best options?
