That's all I hear is that thunder alley is so awesome. But how is it awesome. Are there any numbers showing a hp or torque curve. Where is this pipe picking up power, down low or in the high revs. Does it take the hp over 50hp. Anybody who rode with this pipe on their bike please reply with all info. I need as much hp as I can get, and if this pipe is as good as it sounds I'll order tomorrow. Thanks for your input.
