Saw this on Ebay. Sold before I could put it on here. Is Hindle any good? https://www.ebay.com/itm/176811628738
They are generally decent. Some have better engineering than others. These were actually badged and sold under different names, but they are the exact same product. Hindle Dale Walker's Holeshot Performance And one other... it'll come to me. Oh yeah... Sudco. Had to look at my picture. Duh. I am not sure who actually produced them, but I know it was not Dale Walker's. That was a licensing rebadge for sure. This 4-1 design does limit clearance, and on a stock machine can pose some issues. They perform pretty good tho and sound good (to me).
I ran a hole shot on my SV650 race bike. It was ok. It died a horrible death at Sears Point Raceway. High side into T-10. On anything faster that high side is a helicopter ride. There is these peeps too. https://www.hindle.com/index.php?route=product/category&path=218
Hindle is a good ole Canadian company based in Toronto ... been making performance exhausts for years. They have a really great system for RC24s (I have two)..... some day going to see if they could produce some slip-ons for the VF1000Rs This VF500 system doesn't look used.... $250 was a steal.
