If I were to keep the stock headers, what kind of headerback system would yield the closest results to the boxer rumble sound that a UEL header would provide?

this would be with a bone stock setup, no tunes.

I plan on keeping the stock headers for at least a couple to few years, so I was wondering what everyone's opinions would be on header back exhaust systems that would get as close to a boxer rumble sound as possible while keeping the stock header.

Is this even possible? I imagine no, but maybe just maybe there can be a setup/configuration that would get it as close to it as possible...
