Headers are not worth the money and you should also keep your cats. Not much gains in either and on the driver side the cat and factory header is one piece so you would need to remove it and cut it off. Thatās just dumb if you ask me.
Itās not. Neighbor across the street from me just installed one. Weight of the box said 153 lbs. on it. Take away packaging and add in more coolant if should be at or close to 150 lbs.
