I Have an 07 Busa with a Full roaring toyz exhaust, pcIII, air box mod, k&n air filter, -1 +2 sprockets (even though these only help with torque), and i was wondering if it is at all possible to make 200hp or anywhere close? Getting ready to get tuned, just wondering what the number might be. And also does anyone know if my stock busa exhaust would make better power than my roaring toyz do to the loss of back pressure of the RT. Thanks
