A few "basic" questions. I am new to modifications and I am looking for some assistance:
I have a 98 civic Lx sedan and my exhaust manifold is cracked(hair line). My exhaust is shot and I would like to get a new Header and better exhaust. I have contacted DC sports and they tell me that they do make a header for the 98 civic lx. I was told by tech support that the ex header would make my car run poor. I have seen different people online make reference to having a DC sport header on the 98 lx. I understand the problem is the location of the cat, can I relocate it?
What do I need to do to replace the stock header with an aftermarket header? Do I need to extend the wires on the lower O2 sensor?
Also, if anyone knows what is involved, please make a recommendation on header/exhaust system for the vehicle.
Thanks, sorry if this has been answered elsewhere.
ok, as for the headers goes... i think you can get the D16Y8 Civic EX headers and it will fit just fine. as for the exhaust, i am thinking that maybe the Si will work just fine. however, if you want aftermarket parts, then that's ok too. DC are nice... but not much torque with aftermarket parts, because it's aimed more for mid to high end range, plus on a SOHC... u will feel torqueless. as for the sensors... i believe all aftermarket ones have a location for the sensors. if the wires are not long enough... then DIY and extend it with a 10-12 gauge wires and u should be fine.
