I no longer use my car for street use. I am interested in putting a new exaust on the car, headers into x-pipe into mufflers into turndown in front of rear differential. Getting rid of the EGR valve, as well as the whole AIR pump and hose assembelly, plus the cats. Am I going to get a SES light, and will the ECM (computer) force the engine to run like crap, to compensate for a "malfunctioning" emission system?
Any experiance with eliminating emission systems. Any benefits, other than unclutering the engine bay, and getting rid of about 30 lb's?
