i have been looking at exhaust for my 6.0... every kit i have found is advertised as a 4" system... but when i look into it further i find out that the turbo downpipe is only 3.5" and then it goes to 4"... i can not find anyone that makes a 4" downpipe for the 6.0... they are a dime a dozen for the 7.3 engines...
does anyone make a 4" downpipe for the 6.0, or is it just too tight and difficult to do it :confused:

Most 7.3's didn't have a cat. Don't bother if you are keeping the cat on a 6.0l.

is removing the cat a bad idea?

You'll find that the 4in down pipe is alittle too tight of a fit.It will rub when the cab and body flexes.Just use the 3.5,you'll never notice a hp difference between the two.
