You need to block them off some how and remove the PAIR assembly. I simply welded the stock plates shut after cutting off the steel PAIR tubes. Works fine and was free, but I wish I had just gotten a nice block-off kit like BDE. Just did not have the patience to wait and reasembled the bike with the rigged ones. Works fine and no one knows (oops, everyone knows now).
The BDE kit is overkill since nobody ever sees 'em except in my photos but it's really trick. I'd buy the BDE kit again if I had it to do over. I like wasting money on trick pieces like that.
Here's a couple pics of my BDE kit installed.

XXX-Large,
The PAIR valve is part of the emissions system. It introduces fresh air into the exhaust. Which is all fine until an aftermarket full system is used in place of the stock headers.
Then that fresh air can cause some serious backfiring as unburnt fuel is ingited in the headers. Very bad. So removing the PAIR is a needed step in installing a full exhaust system.

You can order from Tom (Warbaby) at www.veltune.com or give him a call at 1-866-826-1534. Tom is very good to deal with. Great pricing and fast shipping with tracking numbers.
Or from brockracing.com.. I've ordered from Veltune and was very satisifed... they were something like $48 or thereabouts if memory serves me correctly... which it doesn't always!
I agree with BT.. they look trick and they're really not all that much $. You want to do it right, right??
Now I've posted this question before, but with not much valuable info in the way of responses. Anyway, I was wondering how would the removal of the pair valve effect the Busa with aftermarket slip-ons?
I do understand the general purpose of the pair valve, but what would be it's effects on a bike with just slip-ons? Inquiring minds want to know. I'm sure Johnnycheese can shed some light on this subject. I've always been curious and it's basically just for shits and grins. My guess would be that it should really do nothing to a bike with a bolt-on exhaust. Of course I could and might very well be wrong. Just have to wait and see what results we get.

all the pair does is pump air into the exhaust does nothing to gain or lose HP junk it and get rid of 2.5 lbs that the busa does not need

VERY interested in this thread...AZ has frikkin' emissions for bikes. Will it still pass w/ PAIR off? I hate the idea of pourin' half burnt air back into her...and anything that helps slim her down (as long as it doesn't involve me cuttin' back on brewski's
).
