Is it important to remove the exhaust valve from the header, or leave it alone?
In addition, I usually remove the cat from the header if I have time. Has anyone done this instead of replacing the full exhaust, which I can’t do. Is there a cat in the muffler itself, or just in the hernia in front of the exhaust valve on the header?
thanks
