Test pipe & CEL

Sup guys i have a 91 bone stock and my cat is shot so i prefer to just put a test pipe instead of a cat because i dont need to pass emissions where i live, but my questions is if i just slap on the test pipe will it throw a code and make the CEL come on?

Anyone?

No it won’t.

Our cars have a single sensor.

Only cars with two O2 (pre and post cat) will trip a CEL, as far as I know.

Thanks man.

+1 No it won’t. It would only matter for emissions.

FL doesn’t have anything like that, i mean im sure cops will be more willing to be dicks but nothing crazy. Im going to keep my old cat just in case i ever need to pass emissions.

In Massachusetts we have only safety testing for obd1 and older. I have a 3" turbo back with no cat or resonator and it’s perfectly legal :ohyeah:

I don’t know a single cop in Florida that would take the effort to look under your car to verify tht you have a cat converter. I’ve been running a test pipe on my CRX for years with no problems, or codes. Our cars only have pre- cat O2 sensors, so the ECU will not give you a code.

I was so happy when they got rid of exhaust testing in FL.

yeah man one of the perks of living in FL. But i’ve heard stories of cops being complete assholes and just looking for anything to give a ticket, but yeah lets prey that doesn’t happen lol.

Also i’ve been looking into the megan test pipe for our cars. Now it should be a direct bolt on right? i have stock headers and exhaust for now. I saw the inlet size for the Megan test pipe is 2.25 and the outlet would be 2 3/8.

Anyjuan? anyjuan?

Yes Megan test pipe is 2.25 and I just ordered 100 headers off eBay from edge preformance and the test pipe is nice, If I wanted to I could throw my Rsr on there but it’s just a daily lol

You may run into an issue with having a gap between the test pipe and the exhaust system. Your best bet is to buy a 2.25" adjustable length test pipe and run that.

Na you won’t just order 1990-1991 Integra length headers you will be ok trust me, unless you have like dc, or greddy headers you won’t need to worry about it

Thanks for the info guys
