Kinda late to this party, but I just wanted to say how happy I am with the Speedwerx tunnel dump can that I just installed on my 2010 M8. I've always had to deal with the exhaust side bog on this sled and it has really limited what I can do on it, maybe even more so than I thought based on my experience yesterday. First day out with the tunnel dump, and the 12"-18" deep snow was heavy. Previously I would have been dealing with with the exhaust bog all day, but not this time! The sled never hesitated once! I had it layed over on the right side and barely moving for 30-40 seconds at a time and no bog! If you are experiencing this bog, I highly recommend the tunnel dump!
