Decided to get the AIS off the new bike. Took some aluminum
stock from Lowes and fabbed a plate to cover the existing
opening at the exhaust. Clean and simple, yet easily reversible
if need be at a later date. Just reused the small metal gasket
that comes on the system and bolted up.

I've got something similar but its made out of steel stock. One day when I move out of CA I'll block the smog off again.

Not at all. There is not really a power gain when removing
the AIS. Most, like me, do it for a couple reasons. The
first is to help elliminate the popping on decel, and the
second is to "declutter" the bike a bit. :)
