I don't know of any pipes that bypass anything like the Cats and O2s that may cause an alert.

Probably not.

I love the way it sounds when doing the by pass. Not to loud but nice deep tune.

I'd swap out the cans before the x pipe as they are very restrictive. I did this and both performance and ebony rose a bit not to mention a deep throaty sound. Once I get through the gears it's as quiet as a mouse unless you tramp on it.
