I couldn't get those damn bolts off to save my life so I packed everything in the trunk and paid a local shop $70 to install the new muffler. I think if I had a lift or ramps I could have done it, the car just sits too low to do it with ordinary jackstands.
Looks great, sounds great - only problem is that hitting a rather large ripple in construction on I-95 at 60mph during my regular commute produced a noticeable "thunk", I am guessing it is a little excessive play in the hangers of the new pipe (they give a bit too much when fully extended?) Maybe too much flex in the BavAuto donuts? I gave it a push/pull by the exhaust tips and it didn't seem to give any more than before.
