MUST HAVE TURBO! well, damn, dont need these Sharkracing 4-1 headers, or AEM CAI both for a 97-01 tib, and the headers fit an elantra of those years i believe. both brand new, never installed. asking cost for the AEM ($195)still in the box. i'll even pay shipping. asking 400 for the headers. thats' a $30 savings over SR, and you don't have to wait long for either product, as they are understaffed and take real long to ship stuff lately...
