My 2005 with the laser extreme quad exhaust, cat eliminator, and modified airbox. Lots of popping (air induction system, moreso now than before), and some TPS related (I think) throttle lag that is being fixed under warranty soon. Also some commentary from my roommate from his upstairs window :)

A dyno run with the RS Owners Club at Motoscope,Northallerton,UK...results at the end.
