    Newb here, quick question about the FF exhaust

    i have a completely bone stock 2000 gp1200r. i am doing the FF exhaust mod with the PVC pipe on the ski. question is, does anything else have to be done to the ski in order to prevent anything going wrong with the ski. ive read that PVC has melted in the past, so i def dont want that. any knowledge or heads up on this would be GREATLY appreciated. i dont plan on doing anything else to the ski...just basically doing this for sound. thanks very much guys.

    you are fine

    just cut the hose correctly and maybe double clamp the PVC

    with the PVC you can also drop a dollop of araldite around the rim each end creating a "lip" so the clamps work more effectively and wont slip off the end

    over time the cat will fail thats why we run dplates....a failed cat can do a fair bit of damage so its a good idea to replace them befoe they go bad.

    alright guys. i finished this mod today. went to a local exhaust shop and had them cut me a 3.5" SS pipe to fit up perfectly. ski sounds bad azz, its not obnoxious, has a very nice lope/rumble. everything was double clamped.

    quick question though...i left out the large foam that was in the rear. does this need to be in the ski or am i fine without it? what is it there for? thanks again guys.

    The dreaded foam block... 10.00 bucks says you cant get it back in there in one piece

    Its for flotation. I usually leave it out
