stereo exaust sounds?    Being the only savage in town with bilateral rooster tails?

 To my knowledge there would be no performance benefits.

In a word, no, I think (depends on the mufflers) you'd be adding weight to the bike ,and might be making it harder to tune. 2into 1 adds to performance ,1into 2 just adds complexity .
   The Honda 450 above may have a cam with overlap and with unequal exhaust pipe length may have better power do to doubling it's chances of wave tuning( weaker but spread across more of the rpm range). T he savage cam has zero overlap and therefore zero chance of wave tuning, thus no performance gain with a stock cam.

Gary ,Did you notice any increase in performance?

Not on a Savage for sure.

However on something like this:

250cc single. about 50 hp. 155mph or so top speed. Alex Rins finished third in the 2014 Moto3 championship on that bike.

The reason I asked is because I got very lucky this week, I found an 85 gs450f at my local junkyard. I got the wheels, (mags 16 in rear, 19 front). The rear has same axel, the brake hub is a direct fit so once I get the spacers right the tab a in slot b  works no probs. No mods on that side. The sprockets and chain are in good shape so the chain mod is almost free and gives me a good place to start figuring sprocket  tooth combos. The mufflers are cool and in good shape.( Hence ; a silly exaust question).  Also got the gas tank. brackets for the rear pegs and mufflers, also a perfect start on rear sets. I haven't tried the front wheel yet. Doing that tomorrow hopefully that goes as good as the rear. It looks awesome with the mag on the back. I got a bunch of stuff for $100 bucks and found almost all the parts I was looking for. I will keep posting as I figure out what works and what doesn't. Have a great weekend everyone.

I wasn't seriously thinking of using both of them, I've been learning about how the exaust works and I got both mufflers,so that got me thinking about it. The guy on u tube   didn't cover that configuration. I didn't know our bikes do not have valve overlap. Now  I get it.  I got the baffles with them plus the back plates are adjustable , hopefully I can open them enough, they are Short and look cool.
