Make sure those headers for that price are ceramic coated INSIDE & OUT. If they are not coated or just painted, they will discolor almost right away and start to rust out in a very short time. Plus the ceramic coating keep engine bay temps way lower. LT's will require you to move the cats back about 18" and splice the O2 sensor wires about that much longer. Not a big deal, especially if you can weld. I don't think you have to move them with mids and I know for a fact you don't have to move them with the shorty's.
The diablosport, to my knowledge is still not out for DCX Hemi's. The LX release (Hemi cars) has been well documented as blowing up more than a few engines, prompting Diablo to advise that the tuner is not suitable for engines with ANY mods (WTF?)
The horror stories I've read about coupled with a delay of over a year now in getting to market has made me lose all confidence in the predator and has me looking very seriously at the SCT tuner, now that I've outgrown my Superchips...

Here's a couple pics of my Pacesetter LT's with a custom ceramic coat taken while I still had the tire wells off. I'll try to get under and take a pic of the relocated cats this weekend.
