as said in the other thread... Thats a dyno run from the previous owner of the pipes. He had them on a 900Sie racebike. As I understand it, that run is with an open airbox and all appropriate tuning to get the best from the exhaust. No other mods.

I bought the headers used and then bought new cans to go on the end. I had them on an '03 SS800 for about 8 months, when a car decided to pull out in to oncoming traffic and hit me head on. Bike was totalled, I made it out with a broken collar bone and fractured bone in foot. That was last november. The pipes were actually pretty much untouched in the crash except for one scrape on a can outlet, but the insurance company totalled the bike and the money didnt work out in my favor to buy it back.

If you have the aluminum (beefier) swingarm, you may have to do some modifications to the flanges to have enough room to install them. There is a little more room with the older steel swingarm that Hindle designed the pipes for.
