Question New headers-O2 bung or no bung

So, I think I might finally pull the trigger on the MJS perfomance headers for my 08. Stock, the bike doesn't come with O2 sensors, but is the bung needed for when the bike gets tuned?(another thing i'm finally going to do this next year)

The tuner will use an exhaust has analyser as part of his set up.

A dyno shop will have a sampler that sticks in your exhaust from the end. So no a dyno shop will not require a bung.

Any wideband "autotune" (Woolich, Bazzaz, Power Commander, Etc) will require a bung.

My 2c: Get the bung and buy the $5 plug when/if you're not using it. Much easier than pulling the system and getting one welded in later.
