I have been needing exhaust for my 85 for a long time. Bought a few from hedman and hooker and sent them back for bad Q/C.. I bought these http://www.jegs.com/i/Hedman/500/69230/10002/-1 and they fit PERFECT. I do not have a performance engine. Its all stock. Auto also. I did not have to remove anything to install. I did not have to DING or BANG anything to get them to fit. Best header ever for a simple install, and they come with everything you need to bolt them up!! These puppies dont even hang what so ever. I used the hooker max flow muffler and could not be happier!!
