I have a set of headers and an offroad H pipe that my friend removed from his cobra, I was told they are mac's, I bought his whole exaust and only wanted the catback, the silver hts coating has flaked off them and they do have surface rust on them, I was going to get them blasted and ceramic coated, Hpipe looks good but the hanger's have been cut off. $350+ shipping and pay pal fees. i can take some pictures and email them to anyone interested, thanks
