[Pro Flo]

I finally installed my MBRP dual 6" stacks yesterday and wow they look awsome on my F450....does anyonr know of a muffler that can be installed on these cause no room under truck cause of delete pipe,the woosh is not as bad as i thought it would be but at WOT is sound mean.I'll try to post pics soon.

I think I can get integral stack muffler from Grand Rock I am sure they will work, a 6" stack is a 6" stack.

I just put 6" grand rocks on mine too. Went ahead and cut an oblong football shaped hole in the bed to get the Y down below the bed floor so the stacks come almost level with the cab. Install was quick n easy. I'm gonna ditch the 6x36" mitres and order some 7x36" mitres.

It looks 100 times better than some jag-ed metal
