That's actually a regular one. Thanks for the heads-up. I talked to the seller, and he changed his ad. I've found several regular ones for sale and might go that route, but still looking for a Hipo.
The most noticeable difference is the Hipo has the top bracket mounted to the back of the tube and the lower bracket mounted to the front. The regular has both brackets mounted to the rear of the tube. The bends are different as well to clear the Hipo exhaust, but probably hard to tell unless they are side by side.
Thanks,
Rich
