I have a Magnaflow #16887 cat-back system that I installed last winter. As it has gotten warmer out and I have the windows down, I have noticed a fairly loud tick/leak, especially under acceleration. I have had the "flange" connections apart between the x-pipe and cats a few times trying to fix it, but I finally took it to a shop today, and they said that its actually leaking at all 4 band clamps. Is there any fix for this (other than to weld it)? It is very annoying, and needs to be corrected.
