The factory 6.0 head pipes are 2 3/4" or 2 7/8" (depending on who you ask) so I would go 2.5" true dual at least.
2.5" miniumum. But with the fact that you are prolly going to mod it--I would do 3"...

99RCSB Broke because I wasted thousands and thousands of dollars on my truck.
The mufflers and xpipe are 2.5....reason I asked was when I had my 383 stroker in it it had 2.25 pipes.
Yes I am going to mod it eventually but seeing as I will be a dad again in January the truck will be on the back burner.
I think for now I'll do the 2.5 pipe and when the conversion headers are done I'll step up the 3 inch.
