Longtube headers pretty much force you (or close to it) to drop the k-member, which yes, is a PITA. Mid length and shorty's are a little easier but still a tight fit. Its pretty much said if you arent going longtubes or a quality set of mid-lengths, dont bother with headers.
And catbacks really wont give much HP yeild, just more of a sound preference.
Ive had quite a few people tell me one of the best bang for the buck mods they did was a catless X pipe though. I just picked one up myself, but dont have it installed yet so I cant make that judgment. I dont know if the hi-flow catted ones offer the same gain, I imagine some though.
Sadly, these engines dont respond to mods like your 5.0, or the DOHC 4.6's.
And off topic a bit, but the RPM Outlet BBK/C&L TB and plenum combo is actually a BBK TB and a RPM Outlet plenum, but with the same design as C&L. Says its C&L patented, so I assume that means its the same casting, and offers the same performance. If so, thats what I will go with over the PP unit.
