I have a 2003 Hummer H2, and I have a few broken bolts on my exhaust manifolds. I've learned that this is a problem with these engines through online research. Also I had to replace my catalytic's because of this issue. My mechanic has told me that this is a very expensive repair, can anyone help me?
