I'm in the process of getting the whole EX exhaust system for my 97 Civic DX 4dr.
I just got a DC Sports ceramic header for the EX. Now I have to get a Random Tech. High-flow catalytic converter and Apexi WS catback exhaust. When my mechanic guy installs these parts, he'll let me know if I need to extend the stock O2 sensor. So Casperelectronics is the place to solve that, huh?
