    Question turbo back exhaust quick question

    Hey, i saw a turbo back that the guy said would fit my sti ra. Now i don't know much about mods and i wanted to know if i need to worry about things like will it remove the catalyst converter and the O2 sensor, so will i have trouble with emission control or too much noise to pass the warrant?

    can someone explain to me what i should do?

    Thanks

    How are you planning on tuning the car? The CELs from a missing rear O2 sensor can just be disabled.


    Whether or not you will have trouble passing inspection depends entirely on your state, county, and specific place you take your car to be inspected.

    hi I dont know much about tuning or any thing to do with mods. I dont know what to do. I am going to do some research into it now. but if someone can just explain to me, that if i get a rage exhaust from turbo back, then does it remove the o2 sensor? or is the o2 sensor put back? and does it have a catalytic converter? and if it doesnt then are there issues with emission, btw im in new zealand.

    Thanks

    I will try to answer my own questions by research now. but if you can give me any answers it would be good too.

    Some exhausts remove the rear O2 sensor, many do not. Same with the catalytic converter, some aftermarket exhausts come with them, some do not. Many companies make both a catted and non-catted version of the same exhaust.


    I'm not sure what the emissions laws are in NZ. In the states it is illegal to remove or modify ANY part of a car that deals with emissions. However, that means that nearly everyone on this board has broken the law. My car has no catalytic converters and I have no problem passing inspection.
