Correct. The Area P exhaust system is a full system, meaning that it comes with headers and a can; everything from the exhaust ports back is new, hence it's a full system
I have no issues with O2 bungs in my Muzzy full system. Works great. Just let Kerry know where you want the bungs (show him pictures) and he'll likely be able to do that for you so all you have to do is install the exhaust system and screw in your sensors.
The catch is, this system is still not being made, so it depends on if this second short-term GB goes through or not I guess. Your best bet is to chat with Kerry about it and see what the two of you can work out. I've heard nothing but good things about the customer service at AP, so give it a shot!!
