If the wave being reflected back is stronger than the normal exhaust scavenging the result is a flat spot and that "different" sound associated with it. Interestingly even when my GS1000 was factory stock & new it had a slight flat spot right at 3000 rpm as I transitioned off the pilot circuit.

I don't think they make them anymore for the GS's that's to bad because it sounds great and looks good.

I think you should know by now that it is NOT a super trapp, I myself have one on my bike and it sounds great even without the disc's... When I got the bike it was missing the disc's. If anyone has some and even the end cap they don't need let me know.

Yeah, oh well. Im lucky mine is in great shape with absolutely no dents. The only reason I paid $650 for this bike was the stainless exhaust system was worth about half of it.

Mines not stainless...simply mild steel. Oh well..it still sounds bad ass. I need to figure out how to get the core out of it to repack or replace it...
