whats the best O/R H to get if im getting long tube headers? and if you put O/R H does the check engine light stay on? if so how do you keep it off and does that modual work great? How do you install the O/R H? im wanting to get the emmisions testing then put the O/R H on myself so whould i take the whole h pipe off or just the cat of how easy and how long will it take to do with me and a buddy?

 

If you put long tube headers on your car the factory cats will no longer fit.. so if you stick an O/R H pipe behind the headers that will work fine. But you won't be able to quickly pop the factory catted pipe back in during an emmissions test

 

do the long tubes and offroad H pipe. to get the light off...you could get some MIL eliminaors that hook up at the O2's, or you can get an aftermarket tune to get the rear O2's cut off..then no more light!
