Judging by your name I assume you have an 1989 LX. If so your best bet would be the factory header from an 86-90 Escort GT 1.9. It comes with a header from the factory and it should bolt right on to your car. You will probably need the cat for the GT as well but it should be a pretty much bolt on affair.
ok good im glad someone explained that to me... Again im not very familiar with cars besides just regular maintenance. Im learning all on my own which i think is the best way!!!! THanks All your info is helpfull!!!
