Default Exhaust diverter question

On my new Magnum I have noticed that the good majority of my exhaust exits the left side of the bike.

Would there be any benefit to bending the diverter so it is more even out of both sides while I am installing new pipes?

You closed yours off didn't you? I was wanting to make them both have close to the same flow

no i drilled most of it out from the backside which also means you have to remove the cat, which i did. i have more coming out of the right side now by a little, the tips are about equally sooty and the heat is about the same, more sound from the right though. i am putting a new centersection back in though, so cats are going back in along with the full diverter

You don't get more flow out of the left side. Above an idle it flows more out the right

I'm not an asshole...I just type that way

hmm, my left muffler, until i opened the diverter, got hotter and sootier and more sound out of the left. right tip stayed fairly clean and wasnt cool but wasnt hot either

Less flow, and slower more turbulent column means exhaust sits in the pipe longer, and transferring heat better. Also since it was transferring all the heat. The soot would also collect. Look at the exit angle, bends, and pipe shapes used in the crossover. The design is about the look of 2 pipes, and moving sound over to the left. Not about getting exhaust out

ok so for my understanding of this, why did the soot even out and temps even out from left to right? now both tips soot up fairly evenly, and my left muffler is no longer much hotter like it was before?

Icnrease flow through left, and decrease flow through right. Equalized things a bit.
Think about a thermostat in a cooling system. It's primary job is to keep temps constant. However it's secondary job is to restrict flow to promote heat transfer to the radiator. If the coolant flows to fact. The radiator does not have enough time remove the heat. Same thing happens with exhaust flow
