I am attempting to remove the mid-pipe in preperation of installing a new mid-pipe. Either a titanium or SS. My question, I have removed all four springs, two to the silencers and two to the main headers and I removed the two allan bolts. Is there anything else I need to do to remove the mid-pipe? It does not seem to be budging and I am hoping I don't have to remove the silencers to get the mid-pipe out.
