i purchased new after market obx header for my 2000 hyundai elantra 2.0 on ebay. the header came with flex pipe and one o2 sensor located near flex pipe, located directly under engine . my oem settup has two o2 sensor hookups. one before cat on exhaust manifold and one near flex pipe. car is not street legal. off highway use only. Seller has great ratings with great customer feedback on this system im waiting for his reply. does anyone have any suggestions or encountered this problem? how can i make it work?
