I got to be the guinea pig at our KC area dyno session, since I had no mods on my tour and it was nearly brand new, 3000 miles to be exact.
Dynoed stock at 167,4hp and 154 torque
Dynoed with K&N in stock airbox 168.7hp and 156.5 torque.
Dynoed with open K&N (same setup as KKM) 172.5hp and 156.1 torque
Dynoed with Bassani and KKM w/Mik's Heatshield at 177.9hp and 153.3 torque (See graph below)
Now since mine is a 2000, take off 5 hp and that should give you a rough estimate.
