I have the pacesetter longtubes on my 5.3L and it leaks from the collector. I have band clamps but they dont work very well. Is there anything better out there that would give it a better seal?

 

A welder works well!

 

well i know that but if i ever have to do work under the truck and it required that i had to move the exhaust then i wouldnt be able to move it.

 

V-Band clamps!!!!!

 

Another good option although a little more expensive, and work, is to weld on some ball and socket type collectors. They seal good with no gaskets and are easy to remove.

Flowmaster makes some and Jegs sells them, here is what they look like.
