I paid $200 (plus core) for a head pipe that had the cat removed and replaced the head pipe myself. Got the pipes from a local dealer and I am sure there are other places that do this on a core basis. If you were to have the dealership install it, it would be 1-2 hours of labor at whatever there shop rate is.What does it cost to have the cat gutted? Or have real headers installed? Anybody in AZ have a go to shop?
