Hi i have a ford ranger 3.0 L V6 2000. I currently have a magnaflow dual exhaust system in it. I want to remove my catalytic converter but i have a oxygen sensor after the cat. Will taking out the cat make my check engine light turn on b/c of the o2 sensor after the cat? what damage can the removal of the cat cause to the o2 sensor? any other suggestions please say and also any other suggestions on how to make my truck louder too

thank you please respond

FWIW,here's my .02

Don't do it. I'm no expert but my guess is you will throw your PCM into a tizzy because the exhaust samples it is getting is not within its programmed spec's. It will try to correct the percieved problem by adjusting other engine inputs/outputs and I can assure you these adjustments will not be performance enhancing. More than likely it will cause your check engine light to come on.

Besides, nowadays there is little reason to do given the leap forward in converter technology. It has been found that in the Lightnings that the stock system performs the best and people lose power by going aftermarket. I unfortunately found this out the hard way on my L.

My advice is to stay green and either leave the stock one or buy a high flow after market piece if you think you need it. Besides, depending on where you live, you will not pass an emmissions test and/or inspection without it. It is also "technically" against Federal law replace any part of your emmission system, including exhaust, under 50,000 miles unless it is damaged or in need of repair.
