I know the prob with my dx and putting headers on is that the catalytic converter is in the actual header i have now. I was wondering since i already have a thermal cat-back exhaust would i be able to go out and buy some ex headers like dc sports or something like that and then get a hi flow carb legal cat and get a shop to cut the actual catback so they can go from the header directly to the catalytic converter then to the exhaust? is this possible and if so about how much u think it would cost. I could put the headers on myself not a problem but i was wondering for the cat how am i gonna get an o2 sensor too it or is there only one o2 sensor for my civic like just in the header. Please help me im trying to come up with ideas for this thanks.
