I had the timbersled kit on my m7 seemed to work pretty good just make sure u have the frog skinz vents on the front nose of your sled my m7 had the factory holed vents and would pack up with snow around my filters other than that I loved my kit d&d will be the same as the timbersled
i ran the fire breather on my m 1000 and liked it. it did cause some minor tuning issues cause the air isnt consistant when the powder was deep and melting on the engine The best set up is a stock air box but i did like the fire breather with no major issues
