    Looking to change exhaust with little to no adjustments.

    Do you think a 66-80cc extend exhaust would need rejetting for a 50cc kit block?

    Here's an exhaust picture of the direction I am seeking to go in.

    no way to tell until it is on there, also no way to tell if it will fit past your pedals

    I threw one of those on two different bikes and they run perfect after with a bit more torque at all rpms. No rejet was needed on my 66cc stock engines

    Dumb tip of the day, I used a chrome auto coil holder band bracket from pep boys for the rear Clamp to my frame. Solid as a rock and looks nice also. It fits the large part of the rear muffler exact. Lots of leverage on that long pipe with a 1 pound muffler at the end.

    Going to have to jet for new exhaust looking to install thrusters on my 50cc

    The poo pipes nice but I feel it will add too much weight in addition the thruster would make a excellent heater for the winter.
