Installed the Hindle full system last night.
It went on easily and pretty quickly once I figured out how to get all the plastics off safely.
The welds aren't the best I've ever seen, but they're good, especially considering the price of this exhaust.
Everything fits like it should, and it looks and sounds great on the bike.
The Ninja definitely feels more peppy, I'm assuming as much due to the weight reduction as the exhaust gains.
I'm still in the break-in period so I can't push the limits yet, but I'm happy with this exhaust so far!
