Jerry,
Stainless Specialties in FL have a real nice band clamp that works perfectly on the Falcon Sport exhaust. That said, the smallest clamp they make is I think a 2" clamp, may be too large for the stock exhaust. Measure your exhaust and call them to see what they have. As stated above, the clamp needs to be slightly smaller than the pipe so as to stretch and fit tight but not distort the pipe.
