i have a dc sports stainless steel header that is very badly discolored. it's a little over a year old. i don't have pictures but it is digusting. when i open the hood, the first thing you see is the header. honestly, it looks like some one wiped their ass with it. i don't know if they are grease stains from the hands of the people that put it on for me or what. does the ceramic one change color like the stainless one does?? i think that's the way i'm going. any suggestions?
