I currently run a Hauck pipe on an Apex Mnt. and I want to convert this pipe to dump into the tunnel by cutting off the two upper cans and allowing it to dump in the tunnel similar to an Excell pipe. NOW, my concern is how much ice build up this will create ? Is it worse having an exhaust dumping in the tunnel or exiting out the back . With it exiting in the stock location I still get heat under the tunnel from the pipe being exposed but not sure how much ice I really get built up ? I'm sure the heat will increase a lot by dumping the exhaust in the tunnel and I don't wanna do this if I'm going to gain 20 lbs of ice every ride . Input would be highly appreciated! Once I cut the pipe off and do the mods I'm going to do I can't take it back so I'd like to be certain before doing it.
