IIRC, Clifford used to print in there catalogs that the exhaust would be really loud if you did not have a X-over pipe or make a "Y" pipe into a single system?,louder than a typicle V-8 engine when running dual exhaust?
At least I thought thats what they used to say?
Personnally, I would run a X-over pipe just so it would not be too loud, & smooth out the idle,,,if that's a concern?
