CBR1000RR

Below is a CBR1000R stock, compared to a Sato and Arata slip on. Pretty much the same power gains however the Arata makes a little more torque while the Sato makes a touch more h.p. 151 stock, 153.6 (Arata) and 153.8 (Sato) with the slip ons.

CBR1000RR stock vs Yosh system vs Arata system. NO MAPPING, JUST the system for both. 5 more h.p for the Yosh, and only right at the end, where the Arata gains3-5 all the way through and 10 overall. 

 But take a look at the power difference when measured in time: The Arata and Sato slip ons make about 10h.p more in 3.5 sec's than the bike made stock. PLus gets to the rev limiter 1/2 sec quicker. Not bad.

Below is a CBR1000RR with a Jardine slip on, and then mapped. The bike came to us with the pipe on it, so we don't have stock figures.

And just as a matter of interest, below a different bike (CBR100RR with Arata system), compared to an '04 R1 with Yoshi slip ons we mapped check out the power and torque difference at 7K. WOW
