this past june i bought a caback exhaust and headers from ebay for my 99 civic si, when i went to ebay i just typed in 99 civic si headers and catback and just got the ones with minimum price. but i have this problem maybe u guys can relate. the resonater that came with the headers has to be turned sideways in order to bolt on correctly to the catback know what i mean? my cuz was sayin the flanges to from the catback doent match the resonater or the the other way around resonater dont match the catback. and if i plug the o2 sensor it would be hitting the ground cus the resonater is flipped , and i need it plugged so the engine light can come off , is there and easy way to fix this? i was thinking maybe just gettin new headers and catback or can i put the stock catalic converter back were the resonater is or is there another way?
