Question:

I'm busy building a custom bike with a 4-pot engine.

Now ideally I want to pair up two cyllinders into a two-into-one exhaust on either side for looks, but I also don't like the 4-pot sound through open pipes so I'm wondering if it would be good to pair the cyllinders up the way you would if you'd be making a twin-scroll manifold, i.e. 1 and 4 and 2 and 3?

Would it still run right (I don't know why not to be honest) but more importantly; would it alter the sounds a lot and make it less recognisable as a 4-pot?
