3.5" MBRP Downpipe gaskets

[new2deisel]

Am I the only one that has problems with the gasket from the downpipe to the cat? I have had to replace them like three times now. I keep using the ones that MBRP sends me. Is there a better way?

Delete the cat and straight pipe it. No more gasket problem.

I agree! There is nothing like the sound of a straight-piped 6.0L! No kitty or muffler here!

Some folks need to swap the cat and delete pipe out for smog,,as I do. Just run a bead of copper rtv on the flange and bolt it up,, no gasket needed, no more leak.

use the orange high temp stuff.

I do need to be able to keep mine for warranty reasons. I never thought of rtv.

I used the Copper RTV for mine.
