i saw a company dyno 8 pipes for the 450r. they didn't do trinity but they did do sparks and it was dead last, for horsepower and torque. now, between the 8 pipes i think there was only 1.5 horsepower between the most and least powerful.

I doubt it was the BC either, cause Ive seen the Sparks BC go for 2 more HP on a dyno, but every dynos different.
