hello protege enthusiasts I need your help

[xxroll4lifexx]

I am an owner of a 2002 Mazda protege 5, since I have owned it I have had Nothing but issues with the exhaust. I am the 2nd owner of the car and When I bought it I was aware of the random loss of power once it hit 65 on the freeway. I fixed that issue with a aftermarket precat cause the oem one was falling apart into the catalytic convertor.

Now Im having problems with the cat and resonator..

My question is, can I run a resonator off a 2000 Mazda protege on a 2002 Mazda protege 5 and will not having the cat in-between matter all that much?

Welcome.

I can't answer your question about deleting one of your cats, because I don't know what laws are in effect where you live. I can say that it seems likely your precat may have damaged the cat behind it. I hope you find a cost-effective solution. Post in the BJ chasis section for more and better information.

I don't remember where the rear O2 is on the BJ anymore, but if the second cat is after it you can remove it. I know some of Washington state has Emission testing, so don't scrap it once you removed it.
