I have the polished whipple and it was on my 03 H2. We are selling the truck so I took it off and I have the supercharger for sale on ebay. It is cool but now we are looking at heavier boats and I need a dually or a topkick. I had it for about 6 months (4K miles). After talking to everyone that I knew and researching the options I liked the whipple the best. I would also recommend the Billy Boat exhaust.
