MBRP cat delete need gasket

[cowens677]

My wife gave me exhaust for christmas and I was looking in the parts bag and there was no gasket for cat. But I have the cat delete pipe that I am going to install does it need the gasket? And also when you cut the mid pipe to fit your truck do you cut it with the saw zall? I have never used a saw zall and want to make sure it makes a clean cut.

Yeah cut it with a metal blade on a sawzall. Is it a turbo back kit?

4" turbo back stainless steel but it is missing the cat gasket, I guess I will call them next week hopefully mbrp can send one.

I don't remember there being one when I took mine apart. Mine is a trubo back kit though. Maybe someone else can chime in.

in my cat back kit, using the delete pipe, it didnt come with a gasket, but should have. i just lined it up very careful and tightened it down, doesnt leak at all. it is a bugger to get lined up though, you have to make sure the entire pipe lines up perfectly with one another and tighten it down. a donut gasket deal would make it much easier

yes it does. I went thru the same problem as you. No autoparts store has one, the stealership might. All I did was get the blank sheet of high temp exhaust gasket, then traced on my pattern and cut it out with a sharp knife. I believe I got the sheet of gasket material at car quest, I am sure napa would have it too.

The parts list that comes in the box lists it so I am hoping they will send me one. But I don't think I can wait that long to recieve it, so I am sure I will test it without a gasket for a while first.

Ok, I'm confused. What truck do you have? A 6.0 or 6.4? If it's a 6.0 then you will not need any gasket for the cat, especially if your doing a turbo back kit.

If it's a 6.4 and your doing a DPF delete, but leaving the DOC or "cat" on then you probably will need a gasket.

6.0, cool if I don't need it that would be perfect! It lists it on the parts list so I figured you need one but it sounds like most people do not use one anyway.
