Has anyone used a T-Bolt style clamp in place of the normal #72 worm gear clamp for their exhaust system? If so, what brand and size did you use?
 
I put them on my set up. Where my exhaust is more of an oval shape than round, the seal is not that great. The T bolt clamps look better but don't form well to an oval shape. Turned out to be a waste of money for my application.

Thanks for the heads up. I was concerned about those lower ones that are oval shaped. Guess I'll stick with the worm gear ones.
