Mods for 2003 650L?

I tried to order the E series white bros. and i was told it was discontinued. Had found a real good price too. Is the supper trapp the same system,the price seemed resonable?

Same system? No. Reasonably priced? Yes. It's probably the best slip-on for the XRL, my opinion of course. I have the IDS2 QC. It's well-made, lightweight, has disc tuning, provides good low-end performance, and it's not too loud. And it won't melt or discolor your plastic.

I put the ISD2 on as well and am happy with it so far. It has been hard to get the jetting right...been pretty cold in the 40's and 50's. Overall, the few mods have made a big difference!!!
