Just so you know, you can't delete the catalytic elements with a crossover, because on the Touring, those elements are integral to the exhaust mufflers. Not that you'd want to delete those elements. A diagram of the stock crossover looks as though someone at some point wanted to host a bunch of stuff in there, and as it is, it's an obstacle course for the exhaust flow to the left side. However, if you're after improved breathability for the engine (need to address both exhaust and intake to gain most benefit of either), you may end up changing to a larger diameter and as a consequence be done with the catalytic elements. Fortunately, in my state, motorcycles are exempt from regular emissions checks.
