So I figured what the heck, just replace everything from the manifolds back. I ordered a Pypes off road X pipe and another Flowmaster cat back with Super 44's and a couple of SLP tips. After tearing into the exhaust system, I found that the previous owner had installed 2 1/4" pipe on the cat back. the welds looked alot like, well, chicken $^!#. If you have not heard the combonation of the components, I suggest you try it, unless you like you neighbors.
