Can you follow up on that? I know I would need to pull the catback and I would for the C-beam plates but if I can going to do that I am going to replace the motor mounts and my question is if anyone has found a way to replace the motor mounts without removing the stock manifolds...if I am going to do that, I think I should waiting until I can buy headers, the stock manifold have never been off and I am sure they will need heat and probably break a stud or two.
