I have an SVT exhaust on my 98 tour. I'm still debating the overall benefits and haven't made a final decision.
Looks/Appearance: needs new tips to look good on a non-SVT rear bumper.
Sound: Very nice, cold morning starts are awesome. Gives the Zetec a nice growl. Would be louder with removal of the resonator.
Performance: Yes, you will lose some back pressure and removing the res. for volume would make this worse. It's great once you are going but off the line you lose torque. Gas mileage went up, mated with a KKM induction. You must have a free flowing intake or there won't be enough air flowing through the engine to make the exhaust useful.
What your talking about might work a little better. The SVT pipe size is a big increase over stock.

By The Way, these are E1 wheels on my Zetec.
