The urea injection isn't the problem, I believe the injection is taken place shortly after the particular filter. Manufacturers can make an axle back exhaust if they choose to do so... I might get this started in a few weeks. I love the sound of the engine and all, but I think a nice exhaust tone to match it would be great!

I think it's the extra emissions requirements (urea injection) in the US that make aftermarket exhausts tricky.
