I can see both sides...
I appreciate the effort, but I agree that doesn't seem that effective.
I am about to cut mine off but I am worried that it would endanger my dogs when they ride in the back with a shell. I was thinking about making some sort of quick connect/disconnect thing for it, just so I could cut it off, save the tailpipe, and then just have another piece of tailpipe that would go over the cut piece, maybe held together with a screw.
I also live in Utah and they are total bitches about safety inspection. I could see if they failed me for a cracked windshield, that would be acceptable. They failed me for having a cracked turn signal, there was a little 1" crack and that was enough to fail me. I had to order one from eBay and wait for it to get and install it before they let me pass.
A good traveler has no fixed plans, and is not intent on arriving.
