Think about it, it's not called the "UEL rumble".. it's the BOXER rumble  |
No actually, in a 4 cylinder engine, whatever the layout of it is, only one cylinder will fire at a time then the next and so on. You also just said "boxer rumble" and then said "UEL promotes the SOUND" hmm... Then the exhaust is what promotes the BOXER RUMBLE.
Boxer engines do have their own characteristic sounds too but it's the exhaust and exhaust piping that does the music.
