Hey guys i have been looking for a header for a while and i decided to check out ebay. There are DC sports 4-2-1 headers on there for 280 canadian which is acceptable. But there is a knock off 4-2-1 header that is polished for about 100 canadian. Do you think that the dc sports will gain more, last longer to be worth the extra money?
