You can in fact drill out the non-functioning side of each muffler and as mention you'll pick up a nasty resonance (drone). Of more concern is the restriction in diameter going into the front of the resonator at the front of the stock exhaust system. The welding there ends up choking the diameter to 2 1/8 in. This is a performance hit. Many of us have removed this one way or another.

I use to hunt pest varmints here in the US in the open country of Montana. Know what you mean. There was a bounty on some species. Take some night vision pics and post if you have the mind to.

As for the head light buckets design issue and hardware placement you mentioned before, I totally agree. I'd love to write a personal letter to the designer. I have to think he was pressured into leaving it that way for redesign cost constraints. (management)
