LW won, so I gave it a shot, and yeah, it's way better.) Leave the front cross member in so when the manifold nuts are undone (easy to do under the car with extensions) it has a place to rest while you make sure everything (o2 sensors) are disconnected and such. I'd leave the tailpipe portion in unless you need to weld something there too. Just remove from the manifold connection to the back of the resonator.

And 3 credit hours of my college degree are from a welding class. Long ago and in a galaxy far, far away. Oxy-acetylene and electric. Where I grew up, many of the local farmers had oxy-acetylene setups.
