just but on my new longtubes and offroad y-pipe but now i have leaks. i used band clamps for the collectors and used locktite on the head bolts but still it leaks. any suggestions?

 

i used band style clamps and didnt work for ****. i switched to the regular u bolt style and work fine. Headers no leaks and no leaks at the headers of ypipe.

 

What year and engine truck do you have, as well as which headers, etc.? If it's a GENIII, I'd recommend using factory gaskets where the headers bolt to the head, and if the leaking connections are slip ons, you could coat the areas to be sealed with some high temp rtv (copper tube, comes out looking orange). I've used it many times with great results.
