Well my stock elbow was ripped bad on the bottom part near the throttle body, so i when i found this out i ordered the vorteck polished elbow that someone was selling on this site. Well i dynoed before and after with the elbow and a TB bypass and going from a ripped elbow i gained 11 hp and 6 ft/lb torque. Just figured ide let you all know incase you have a ripped elbow as well, also now get more mileage to the tank also.
