Okay, one side of my stock system is now off with the O/R H ready to accept my new MAC cat-back. The problem is I cannot get the muffer/bent tube over the rear axle. Everytime I try it catches on the control arm or parts of the body. Anyone have any ideas how to manipulate it over the axle? I'm using a standard jack on the rear and have it all the way up... plz help thanks!
