what do you really mean by the noise on deceleration. I already have straight pipes, will it be a hell of a lot louder??

This is one of the "features" of Stage I, and probably the feature that would be most likely to keep it from being smog certified. The new PCM goes rich on deceleration which allows unburnt gas to get as far as the cat. which causes it to detonate in the exhaust pipe causing a harsher "burble" then stock.
Hope this makes sense.
