I did have favorable results switching to Silbers Lightweight silencer.
No bog with snow sitting on the top of the hood, or in turns in either direction. However, it’s too loud for my liking.
I haven’t had the opportunity to switch back to stock clutching and stock exhaust to test. With the snow prediction in IP this week, may have an opportunity to test some more this weekend.

I haven’t had any trouble with a bog since I switched to the Diamond S can. I haven’t had the opportunity to ride in real deep snow either since the day I experienced the bog. I can say that I can’t replicate the bog by piling snow on the intakes though.
IMO, it's simply bad Ski Doo design. I've had several Doos (they're all I've ever ridden) and they all bogged in deep snow, not for any technical reason like aftermarket intake filters, or engine bay exhaust due to improper chamber intake valves etc. etc. The deep snow covers the vents 4-6" deep and it just chokes off the fresh air. Finally on my '19, Ski DOO put the fresh air intakes on the side of the hood with a vertical face, and further behind the front of the sled making it much more difficult for snow to clog the fresh air intakes. That '19 never bogged, ever. But for the '22 turbo, BRP engineers decided to go back to the fantastic design of putting the intakes on the horizontal face of the hood, and towards the front of the sled, making them clog constantly in deep snow. I think I am going to add a frogskin on the left vertical side of the hood, and am betting that will completely eliminate the issue or make it 95% better. While I generally love Ski Doos, they don't ALWAYS engineer things properly, as anyone who's ever installed their adventure bumper (front or back) can whole-heartedly attest. But I can tell you, it sure sucks ass when in the deep, when you want that turbo to power you up and out more than perhaps at any other time, the ****ing thing chokes and leaves you sinking. This year, more than any other, I really REALLY want to meet someone at BRP and kick him in the nuts.
skip to 8:30. this guy tapes up his vents on the lightweight hood at 10k feet and rips around for a half hour. the sled runs fine because it's pulling in air from the engine compartment via the vacuum operated intake or the "air duct assembly" as brp calls it. these sleds let in too much powder into the engine compartment when in really deep snow so maybe the screen on that auxiliary intake is clogged. or the spring controlling that valve is stuck or too tight.
I switched to the Diamond S can and added a Frogzskin to both sides of hood, no more bog. See picture below
Nice job with the frog skin.
Have you noticed anything odd in the midrange with the Diamond S, from just off idle to wide open or a cruising around about 6,000 the stab it?
My 22 has some odd stalling of motor RPM under certain throttle positions with the Diamond S.

We also offer a purpose built additional intake for the Turbo/Expert
What screen material is that?!? Looks like regular bug screen.

I feel the vent in that position will be more prone to tearing when tree riding.
Prefilter backed with mesh for durability in the trees.
Your probably right. Frogskin vents are pretty inexpensive so if I tear one, no biggie but I feel they flow more air, which Is why I choose it, I carry a couple extra, just in case or Gorilla tape worst case. I also like that they match the factory vents, which I’ve had no issue with.
