i have a 98 civic lx with a cracked exhaust manifold.. i have heard that i need to get an ex header and then buy a high flow cat with a o2 sensor plug.... is this true? is this the only way to hookup both sensors and not have any issues? is there a header with 2 o2 plugs on it so i dont have to install a high flow cat?


i found this one that looks like it has 2 plugs for both O2 sensors...let me know what you think
thanks
Danny
