That's what I'm saying - I have a jack, but trying to yank that shit on my back isn't working. And if I take out the whole pipe, then the gasket on the cat is probably not gonna work once I bolt it on again. A matter of fact when I loosened the muffler, I caused a leak. The clamps are tight, but I can feel exhuast coming from the pipe. This shit is real frustrating. Some help would be greatly appreciated.
