What a difference the right presilencer makes...

I think we're talking about two different hoses. The one that exits the rear of the LIM above the rear rotor intake is the hose I'm referring. Were you refering to a different one?

The split air pipe goes from the cat, to the big hose on the back of the LIM that is hanging there. On the split air pipe is a small nipple and a vacuum hose that feeds the above mentioned small Y pipe.

So even if you had the SAP you would be no better off without 6 port actuators.

It's been awhile since I actually had a SAP on my car so I very well could be mistaken, it just seems from memory that the 6PI actuators were fed by the back pressure and when the pressure was less than that the ACV routed air through the hose on the rear to heat the main cat. Am I mistaken?

Since he's installed a resonator and header combo, the SAP has pretty much become useless so wouldn't that hose then just become a vent from the Air Pump and ACV?
