Header install w/o defoulers. Should I be worried about ECU

LeaK · 02-09-2023, 09:41 PM

Hey everyone. First time posting on the forum, couldn’t find anything on this so here I am. I’m installing PPE long tube headers in the coming days and I got them with out defoulers. Without them I’m obviously going to have a CEL and now I’m curious if the ECU will try to compensate and possibly decrease performance.

Do you have any other performance mods done (intake, exhaust, etc)?
