It should be noted that at this time, Apex'i front pipe is only available as part of the complete header/FP kit:

Flange positions looks like the Apex'i front pipe could be separated into a standalone part, however that is at the discretion of Apex'i.
Will also look to test sound with this setup on a STX car.
