Exhaust question?

I removed a summit kit that was installed by the previous owner. It required 16 clamps! Too many peices. I ordered a complete aluminized exhaust system for my 69 340 Dart from Antique Exhaust Systems. They are online. The system sounds great and fits well with one exception. They didn't make the L/H down tube quite right. They bent the tube to close to the flange and the pipe interfered with the starter. I cut it off and welded the previous down tube. If you don't weld, the system can be installed with 6 clamps. 4 Clamps an muffler joints and 2 at tailpipe tips. I used 4 clamps total. Two at the muffler/tailpipe joint, and two at the tailpipe/tips. They are expensive, about $550.
