I have a set of shorties with a y-pipe off a 2001 extended cab full size sitting in my shop. I was thinking of putting them on the TBSS but not sure how bad the fit would be. I have a plasma, chop saw and welder, so I'm sure I could hack it up and make it fit, but any idea how far off it would be? I believe the headers to be JBA's. I picked them up with a bunch of other parts..

 

I'm not sure, but 'most' of the pipes will probably be close. I've read a few threads about what fits and what doesn't, but I each manufacturer is different. I'd expect your biggest issues to be the passengers side where the clearance is so tight near the head. You are probably just going to have to try them and see what its going to take to make them fit.
