The primary tubes are longer, but overall it's not any taller than the shorty header/manifold and downpipe. If you really want a shorty header, search for '94+ 2.3L Rangers, they all should have one. The long tube header will extend farther back than stock, meaning you will have to relocate the cat (or get rid of it altogether). Also, I'm not sure which connection is missing on the pacesetter, the O2 sensor bung or the EGR nipple, but no current aftermarket header has both of them.

O2 sensor monitors the fuel burn. It sends feedback to the computer to adjust the fuel mixture (lean or rich). The EGR is also controlled by the computer to feed exhaust gases back into the intake for emissions and fuel efficiency. Disconnect the O2 and you get a CEL and iffy fuel mix (computer doesn't know what it's doing, so it just guesses). Remove the EGR and your engine will run leaner (more good air w/ O2 instead of exhaust gases), will knock and ping more.
