Me too.
The full system wouldn't make the FJR a big polluter. It just doesn't work that way.
The system without cats will not make much difference in sound level through slip-ons. My R1 through slip-ons makes no discernable difference with, or without the cat.
No one knows if a properly designed aftermarket system could outperform the stock system on the FJR. It depends on a lot of factors. It could be a lot, it could be a little.
Removing the cats from the stock system may actually compromise engine performance, rather than boost it. A 'wide spot' in the pipes might seem like it would help flow, but most likely, no. Exhaust is more like a musical instrument.
