What to do with rusty headers??

A wire wheel on a grinder works amazing.....I stripped my entire car this way, does not harm the metal, it took a long time but headers would be done in no time. Even a wire wheel on a drill would work but not as fast. I have not heard of header wrap shortening the lifespan of the headers, it would help with heat, how much I do not know but I hear paint does not last. The header tape would last longer in my opinion. I cannot see how the tape would harm the headers.

sand blast, wash with acetone and paint with some good high, heat paint and you will be fine.

wrap and tape will kill your headers in half the time. the tubes have no access to cool air beeing passed around them as a result the inside of the tubes get so hot that the gasses exiting the tubes start to take metal with them. So they eat themselfs up from the inside out. But hight temp paint works just fine. You can buy the paint that they use for bbq's ect ect. and it will stand up just fine. I actually bought a gallon of it and blocked off the collector and filled the inside of the tubes with paint about 3/4 of the way up to the flange and then unblocked the collector and let the left over paint drain out. Proably didnt come out super even but keeps the inside from rusting out as well
