I just installed my TSR chrome header and wanted to share a few thing with everyone.
I couldn't believe how loose the acorn flange nuts were when I went to remove the stock header. Even if you never plan to change your header, check these nuts for proper torque. If you do change the header, it is a good time to apply anti-sieze to the exhaust studs.
Make sure you test fit all of the pipes in the collector before you start attaching anything. One of the collector outlets holes on mine had a small ridge in it and the pipe would not fit. A dremmel solved the issue.
I had to cut a special pull tie with a tip that fits into the frame to remove the O2 sensor wire. I had an extra one in my toolbox. The tie is located behind the right side cover and holds several wires up. I recommend you have one handy before you start.
The O2 sensor is just stupid the way it is mounted on the stock header, if you need to remove it, spend the $35 and buy the Ko-Ken Socket. Snap On wants $50 for their version.

I have a PC V so I just plugged the hole on the new collector and left the sensor in the stocker
(Props to darmahman for removing it without this special tool)
Overall, I am happy with this header. The larger diameter pipe looks right on the bike and the chrome is definitive aesthetic improvement over the golden stainless. My only concern is possible vacuum leakage where the four pipes fit into the collector. I used the supplied sealant, but am skeptical as to how well it seals, In my opinion. it would have been a nicer piece had the collector and cat been welded to the head pipes. The Staintune with the factory header had a gurgle on decel, but it is much more pronounced now. Not sure yet if that is the norm given the larger pipes and smaller cat or the product of a vacuum leak
Oh, and I applied the Eastwood internal heat coating. Took awhile to clean the pipes with Brakleen, but the coating went on just like spray paint.
