hi raz dude!
ive heard that the valves bleed air into the intake thus giving a cleaner burn. the cat keeps gases in the exhast longer burning the bad stuff, im
trying to find out where to get these valves? and a cat /silencer in one unit

IIRC these are bleed valves on the intake manifold which are adjustable. Bogg Bros fit them to there manifolds.

This sounds much like the Ecotec valve which apparently does similar things. They also claim a significant power increase but I have my doubts.
Anything that ACTUALLY reduces emissions can't be a bad thing but SVA will want to see a cat on an engine that originally had one. I'm
borrowing a cat for my SVA then refitting a dummy cat for the rest of the time.

IIRC=If I remember correctly  Bogg Brothers are well known fabricators /engine builders - if you do a search you will find a lot of results,
especially just recently.

I'm afraid I havent a clue about the R1 cat - maybe other R1 builders will step in here.

For my carbed R1 I fitted a cat between the down pipes and silencer and then adjusted the idle fuel mixture at my local Hi-Q tyre and exhaust place on
their MOT gas analyser to get the readings right.
The guys at Hi-Q were really good as they didn't charge me for using their machine.
I think that some people use valves to bleed air into a slighty rich fuel mixture to get the readings right rather than adjust the mixture but why go
to the expense?

Have a look at this thread:

I used the valves in an emission test last week and it flew through, got my sva on friday so fingers crossed....!
