Hey guys

Problem: I have a 2002 civic 4dr with a 1.7 and i want to place aftermarket headers on it with a catback....but the problem is i have that engine that many of you probally know with that cat built right into your headers. And i need a soulution. Considering the o2 sensors are short and i have heard that making them longer is going to screw up the ecu readings. If possible id like to do a conversion that isnt going to give me a bad reading everytime i drive my car!

Any help would be Great


Thanks

I have an '03 Civic with a 4-1 header (only one available when I got it) which was meant for an Si (not the SiR). By putting that header on, I was able to put an aftermarket cat and then use a catback. Had to extend the wires for the o2 sensors, but so far, I haven't had an issues - this was done back in 2005.

Ur not getting any engine lights ? or anything ? who did the install?

Just my mechanic. Basically, the setup is like the Si or an Acura EL - the one piece header/cat is replaced by the header, which bolts on directly to the engine.
