but how, i thought the stock exhaust diameter for the 5sfe was 2.25'' ?

You don't want backpressure with an NA car or a turbo car- you want to have an effect called "gas scavenging" which basically means the gas particles are close enough to one another to latch on- and pull each other out of the exhaust. If the exhaust is too large and the the particles are too spread out, you won't have gas scavenging and you'll loose some exhaust velocity as the particles are no longer pulling each other out.

For the record, this will have no effect on spool time.

You know a thread is stupid when it actually causes me to post.

Dug this up since it was on the last podcast and it piqued my interest. Does anyone have a picture of this on their car? I'm curious to get a full visual so I can see how the flow would be. Does the valve cover up the straight pipe exhaust portion or the regular cat/muffler side of the exhaust?

It seems the way it's set up is not 100% ideal once the valve is open/closed as there would be exhaust either going by the valve in one instance, or getting caught (albeit just a little bit) in the other with the valve closed.
