Here is a list of the additions for 2003 on the Nissannews web site:
Xterra
Following last model year's addition of a supercharged V6 and refined front end styling, all 3.3-liter normally-aspirated V6-equipped Xterra models receive an additional 10 horsepower (an increase to 180 hp) and two additional lb-ft of torque (now 202 lb-ft) for 2003. In addition, Vehicle Dynamic Control with Traction Control System will be available on Xterra for the first time. All Xterra XE V6 models now come with standard 16-inch alloy wheels and side step rails. Four new exterior colors are available for 2003.

Also I have a 2002 SE/SC with ARB. First OffroadX is right you have to cut notches in the grill to install the ARB but they are minor and not noticeable (Check here:
http://www.automotiveforums.com/vbul...&highlight=arb). Second, there is a noticeable difference in pickup with the supercharged version but everyone else is right in that it costs me a lot more at the pump.
Davruns,
There are a lot of differences between the regular and the S/C other than just the exhaust. The biggest is the supercharger itself which in simplest terms is an airpump which forces air and fuel into the cylinders to give you more bang with each compression. This is where the bulk of the HP and torque differences come from.
