I want to go with a ressonator over a catalitic converter. I was wondering if anyone Knows how to keep the resonator on and still pass emmisions. Keep in mind i live in maryland and the emmisions test is done through the computer so the only way you fail is if an engine check light goes off.

thanks

 

o2 sensor simulator? its the only thing i can think of that might work.

 

can either one of you elaborate because i am not sure what you mean and how that helps me

Thanks

 

not sure if its the same in maryland as it is in MA, but they only do the computer check on OBD2 cars, they still do the sniffer test on OBD1 cars.

If you have an obd2 then search for the 02 sim trick, like mentioned by BB6racer.

I will also take this time to recommend a high-flow cat over a resonator.

 

thanks
