So the taped flap really didn't contain more snow in the tunnel?

Ken it may have, hard to say. This was the first day I rode the PRO on hardpack with the scratchers down, so I'm not sure of the impact of taping over the flap holes. It should have helped some at least.

i'll see if I can snag one later, rivits right into stock holes and the flap "slot" lines up perfect with the pro aluminium rear section, the mounting is a perfect fit on the pro chassis, looks great, just barely touches the stock pro bumper and curves out nice. Also available in black,red and grey..and if ur lucky dark blue and orange but they are quite rare.

the iq flap is curled isn't it? i think when they are rounded like that they help to keep snow in the tunnel. in 10 i had a doo 600rs, had a huge race flap on it but because it was just straight it did not keep any snow in, just let it all go by it. i think the long flap from proven is just goign to do the same thing. i think the iq flap works because of the design and curve.

Good snow flap test today. My buddy's '12 163 Pro with the ported flap and scratchers down was running up to 173* on the groomed trail into Allen Creek. My '12 163 Pro has an IQ snow flap. Same trail with scratchers down, my sled never went above 127*. When we got to the cabin, there was almost no snow in his tunnel, while mine had a 2" layer of slush inside the tunnel.

i think thats proof enough that the iq flap works.

Yea, I just swapped out the snow flap on our 2011 Pro with the one on our 08 D8.

Doesn't get much easier, just four 3/16" long pop rivets, everything lines up perfectly.

Didn't even have to take off the rear bumper to do it.

I ended up adding a Proven Designs snow flap as well. Great product, great people to deal with and they'll do anything you want on your flap to make them different.

High Velocity,

Is that the 09+/- style cat 162" rear bumper? Can't tell from the photo? I put the cat 162" rear bumper on my 09 dragon to stiffen up the last couple feet of the tunnel and it worked great. Wanted to do the same thing to my PRO. I'm thinking the dragon flap and the cat 162" rear bumper on the PRO. Someday these manufacturer's might just get it all right. Until then it's a good thing we have a few manufacturer's to use their good ideas on one sled :)

dude, yes it is the 162 M-series bumper. I cut 7 1/2" off the bumper "arms". I didn't rivet it on. I installed four 1/4" rivet nuts on each side of the bumper and bolted it on from inside the tunnel.

looking at proven designs, they have a bend in it so it stays more vertical, that could help to keep some snow in the tunnel. anyone have one and can comment on the cooling it may provide?

Sorry, don't mean to hyjack the post. real quick...I just put the cat 162" rear bumper on my PRO. I went ahead and rivited it on. Why did you cut 7.5"s off the arms? I would think you would want it going as far down the tunnel as possible.

One of my buddies ordered the bumpers. I thought they were 162 bumpers, but I may be wrong. After cutting 7 1/2" off, they still touch the brackets on the tunnel by the end of the running boards and I even allowed an extra inch overhang at the rear. Hmmm, I wonder if you ended up with a Cat 153 bumper ?
