Black widow headers
#3
I didnt get many post install pics because i just wanted to ride it. Ill get some later.

-The welds all have good penetration. As you can see in my first post, the welds at the head flange to no protude into the flow. The OEM flange welds protrude in the the flow path quite a bit. That alone must make a measurable difference in flow.

-Total install time was about 1 hour 45 minutes in my driveway on the sidestand.

-The O2 sensors were at precisely the correct angle. I was very happy to see that becasue the room for error is almost none.

- I re-used the exhaust gasket at the head and I have no exhaust leaks.

-The exhaust seems to stick out the back almost 1 inch further that stock. This would make it impossible to get a muffler with a fixed mounting point to line up with the mounting bracket on the bike. Luckily, my muffler mounting point can be moved.

-I had to fight the right side flange onto the head. The holes holes were slightly mis-aligned. The cause seems to be from the pipe that connects the two headers was a slightly the wrong angle. Perhaps I got a bad one. Either way it, took me probably 10-15 extra minutes of observing the issue, and then forcing it into place. The left side mated up no problem.

The boost in power in unbelievable. It does not stop pulling. I like to pretend this is a sport bike when I'm not taking long trips and these pipes gave it a sport bike feel. Im sure the power is not specific to this exhaust, but for $375 USD. I was not excpecting the ride to change this much.
