pipe looks good on your bike, what if you take a small strip of steel and drill 2 holes in it one at each end, bolt top end in the exhaust mount on bike
and then you might be able to lower tail pipe and then if you need to you can mount pipe on the inside of that steel. this might help you pipe from rubbing.
and you do have rubber mounts all around on that pipe. i wouldnt run it with out them.
