i know this is an old thread but i run a stock 01 banshee with the t6 pipes and they pull.... hard. if you raced a guy on level ground, it would be close. i mean the t6s compete with even ported bikes. they produce enough torque on level ground to beat some decent bikes. now from experience, if you raced this guy up a hill and he was not bullshitting you, you wouldve smoked him no doubt. but i have raced against our other bikes and on level ground i can give them a good run for their money, but then up a hill against the same bike, i can get a good start but by the time i am half way up the hill, they just fly by me
