I'm running Euro headers, DKF S-pipe, OEM X-pipe, and RDSport exhaust. All the O2 connections as well as the EGT were EXTREMELY simple due to DKF making it simple for anyone to do it (shoutout to Pokeybritches for the DKF!). However, I do have a CEL which is no big deal (sometimes it doesn't let me sleep at night, why lie). My point is; consider leaving the SS headers out of the picture if it doesn't give you much a HP gain over the Euro headers, it's not worth the headache IMO. As for tuning, I'll probably go with TTFS
