Exhaust mount Rotax Senior

Good evening all,
Quick question, what do you guys consider the “best” exhaust mount for the Rotax Max senior?
My Parolin I have now has a mount which is only attached to the right side of the chassis and extends all the way to the left side of the exhaust.
But i’ve also seen other mounts which connects the left and right of the chassis, but this stiffens up the chassis, increasing lift, no?
I’m guessing it has to do with driver preference and all but just wondering in general.
Thanks in advance!

I use a mount on both sides so the exhaust doesn’t bounce around and touch the brake disk or cassette. It’s attached to the mounts with springs so it won’t stiffen the chassis much, if at all. Just my opinion.
