My experience: My original muffler was shot so I got an Aries. It still would not line up exactly even though I left the rear hanger somewhat loose to aid fitting at the manifold. I wound up having a leak so I bought the sleeve and that seems to have done the trick. I also smear on some muffler paste on the joint and you can buy that at any auto supply store. Then I tightened the rear hanger but not to the point that it can't expand/contract. I have heard that there is a possibility of a couple inches hot vs cold. Just know that the hanger will probably rattle a bit. Also, a handy way to check to see just how much of an exhaust leak you have is to put your shop vac on blow and tape the shop vac hose to the tail pipe (car cold). Turn of the vac and go to the manifold joint with some Windex and spray the joint and see how your bubbles look.
