Now who in the hell would buy aftermarket performance headers with cats in them to replace oem? such a waste of 3000k but any way this is my project Im having completed, gutting them. Has anyone done this with agency power? I assume there's gains and noise increase .
Second sides done I decided to remove the o2 elbows as well. Now it's time to reweld the factory welds on the oil cooler and I'll be done. Oil change + dimple drain plug
