I wasn't talking about your exhaust, I was referring to the factory exhaust. Factory exhaust on gen 5 and 6 combines cyliders 1+2 and 3+4. On gen 8 it combines 1+3 and 2+4. I'm just trying to get clarification if running the 1+3 and 2+4 would pose a [long term] problem.

Are the 8th gen different than the 5th or 6th gen? Because, the 8th gen has the front headers paired together and the rear paired together... 🤔

Follow up question, If one replaced their 5th gen headers with equal length headers and set the vacuum equal across all 4, how would that affect the fuel/air ratio? It looks like some cylinders are getting more fuel than others and if air flow is now the same(in theory) would that cause some cylinders to run lean at idle and/or other rpm? or are those fuel maps different just for idle?
