I went with the Pacesetter LTs, here are some pros/cons that I noted with them.
Pros: Cheapest long tube on the market, very good spark plug access, very good power gains, and the slip-fit design yields better ground clearance.
Cons: The ceramic coating started to rust in less then a year, the EGR tube interfered with the tranny dipstick, and the steering shaft rubbed on the drivers side header.

 

2000GTP, mine doesnt touch the steering shaft, so try replacing your motor mounts. Mine has never rubbed.

And FWIW, I can back him up on the plug access thing. I can do all the driver side plugs in 30 mins. if that, #2 and #6 can be tricky if you dont have a nice set of tools at home. If your fortunate enough to have them, do what I did and use two universals for #2.
