hey, thanks! That looks like RS3 silencer for my CBR600RR system as well. Yeah, black magic for sure if you don't have CFD software. It seems like it wouldn't work because it's still straight-through pipe.
Although I'm on fence. I may just build 2-1 system as extra mid-range is what I'm really after. I've already got the later cams, but my 2002 is still too peaky and requires way more revs than my new-gen.
