Well, I read somewhere on here that you can just remove your air pump, and leave the nipple on the LIM unplugged. Then I read that the air pump supplys air to the ACV and other stuff. Now, we started the car with the air pump off and uncapped. Now it ran like **** and would not idle, we had to keep it above 2k. My dad then plugged the nipple with a rag and the car ran much better. Now, I'm going to just reattach my air pump. And run the hoses accordingly, but. Now, I have gutted precats and the main cat is gone in favor of a test pipe back to some ricer fart cans (They came with it!). So...no split air pipe, I'm curious as to should I tap into the Cat shells and make my own source for back pressure? Or should I try to get the air pump to feed the 5th and 6th ports?

Tapping into the straight pipe likely won't work. I've done it, and the aux ports didn't work. There's just not enough exhaust restriction at that point to generate 2+ psi unless you get creative with a series of bends in the pickup tube. That's how Racing Beat designed theirs, and apparently it works reasonably well. The main problem is you just don't know at what point the pressure will be right if it builds enough at all.

Go with an rpm switch and solenoid to control air flow from the air pump. You will also need to put a restriction in the ACV's relief port or the pressure will be bled off above 3500 RPM.

Sounds like its possible, I'll check out the write up I have it favorited.

Where the **** does the vacuum hose from the FPR hook up to I can't remember for the life of me.
