Two Bros. Racing Installation
First, get the patient in position.  Had to move debi's Dang Wang out of the way.

Get tools:

Place Pabst in a safe position.

Remove flange cover trim:

Remove stock big ugly can.  Start of number "TWO" Pabst.  I think that's how Two Brothers Racing got their name.

Cut cat 1/2 inch from flange:

Ouch!  Made me mad.  At least I didn't scorch my forehead.

That stuff's hard!  Wore out 4 blades.

Grind/file to remove any flash and burrs that could restrict flow.

Completed installation:

Perform qualification test by riding:

I guess I'll leave on the pipe for a while.
