Ha...

each pipe to cover the rpm range, like it!!!

The cool factor yes. The weight, i duno, could two pipes equal 1?

Would the sound be any better?

I've often thought if the signature tune of the engine is influenced by the pipe and what additions could be added to create further deeper basser resonance..!! even an airwhistle or something to manipulate the audable sound frequencies for maximum sound blasting....!!!

I want an engine like this.....!!!
