i have a 95 civic lx and im i have a 4-3-1 header and well i dont have a spot to put the o2 sensor and even if i did the cel. appears is there WAY to avoid the light from appearing and have headers, i live in south cali so emmsisions is every 2 years.

just swap back to your old ones when smog is due thats what everyone does but if not you needed to buy headers that have a o2 bung. did you buy universal ones?

Sonic89

oh ok thats sounds smart to me, since its all bolt on it should be a breeze and also cani get in trouble by the cops if they pull me over and check my engine and just see the headers

GeorgeA

yes you can but its rare, if they wanna check you engine bay unless ur exhaust is over the 95 db level or ur lowered to far

header there is only 1.
