IMHO, it would be worth trying to swap with someone on KTMtalk, might save you guys a lot of money.

IIRC, there are basically 4 silencers available from the KTM Hard Parts catalog, the two SXC shaped cans (Competition and Supermoto) the straight can 58405083100, and the new Akrapovic silencer. IMHO, these get you a bit better looking can, that weighs 5 to 6 pounds lighter, with a mild performance boost at least in the case of the Supermoto can, but this comes at the cost of increased noise. None of these give a fraction of the performance increase of the Akrapovic full system.

Do you have first hand experience with the full Akrapovic? I am curious if the cost is justified. I mean, for a $1000 pipe are you picking up gains on top for racing applications and losing bottom end? Or is the improvement substantial across the board? I have only seen European dyno charts that show gains on heavily restricted bikes, and I am always skeptical of dyno numbers.
