    I looked at stock mufflers & they are resricted big time. I could not see a way to get to the baffles to cut them out.

    Find a piece of a tube or pipe long enough and knock them out. I used my load lock one time to knock baffles out when we replaced mufflers on my friends truck.

    Have you tried these mufflers? If so, are they very loud compared to stock?
