    if he is breaking off the bolts at the manifold he has the 720, plus it is a 96 and the 800 was only in the Challenger not the speedster in that year....

    To fix your problem, you will need to keep the band clamp at the mid pipe loose as well as all the mounting bolts. Replace the bushings that hold the pipe to the manifold and use red loctite on the new bolts...There was a service bulletin about this years ago on the skis...

    Once all the manifold to pipe bolts are tight, then thighten the pipe mounting bolts and the band clamp..You dont have to take the band clamp off and the pipe apart but leave it loose so that it will rotate when reassembling everything...

    Should fix your problem
