I've been hearing great things about it...."7hp bump...more than any other s.o."..."better slip-on than Akrapovic, Arata, Yosh, etc."

Anyone have one on their 1KRR?...Opinions?

Thanks

ARATA bar none.

Yup... tons do over at 1000rr.net
One guy got 163rwhp after custom mapping.
Thats with just the slip-on and BMC filters.
His Baseline run was around 149hp I believe.

I have Akrapovic, A quality slip on, light weigh,t and sounds good. It increased my performance.

SATO is in FACT the best SLIPON for our 1kRR's.
all R&T show it, Many Non-owners admit it.
i have yet to see any gains surpass SATO.
good luck.
