my first trans am ran w/ Pacesetter LT's and were pretty easy to install, came up through the bottom and just unhooked to steering shaft and all good...now i still swear that the Pacesetter LT, Off-road y-pipe, and SLP LM1 set up is the loudest an nastiest sounding exhuast out there, but it comes down to preferences and emmissions...but if you dont have to worry bout that go with that set-up, its popular for a reason..and im going back to it on my next f-body, but my last one was running flowtech longtubes, catted y-pipe, and borla cat-back, it had nothing on the Pacesetter, ORY, SLP LM1 setup, i didnt install that borla and flowtech setup, but last owner said it was very easy w/ basically nothing having to be removed...
