The exhaust sounds amazing. And Bill's Exhaust was real easy to order from and they got back to me real quick When i had accidently had my wrong address on my order and they had it fixed before it was shipped.

The fitment is terrible, cylinder 2 pipe isn't even bent enough so unless you have a pipe bender or a lot of time on your hands there's no point in getting this. Also, the bracket for the slip on doesnt line up at all so there's no real support past the bracket on the link pipe. It does sound amazing but I already knew that. I'll update with gains if any after it's on the dyno.
