Gutting cutting 2.3L's cat OEM costs 250 some dollars

[henryj10]

I've looked up what i could on clearing a cat I relize the performance and mileage may suffer but the thing is the cat I have is a rattler makes my ranger sound like a tin lizy. I have all the parts gaskets brackets and pieces of exhaust from the tailpipe to the cat the only thing I haven't bought is the catalytic and the exhaust manifold. the fricken cat costs 250 for the 2.3 and I can't find anything on clearing it does anyone have any advice. Can the cat be cleared in a way that the oxygen sensors( the 2 the rangers have around the cat) are by passed specifically the one passed the cat. Or will this affect the way the computer runs the engine. Can you just do away with the cat all together mechanically not asking for a legal notification? need some help want to avoid spending 250 dollars for the darn thing thanks

ebay or jc whitney have cats cheap. even autozone sells a cat for about 100 bucks but they are universal so you will have to clamp or weld them on. gutting you cat will get you post locked. you will fail emissions. gas mileage will suffer a little. performance will be 1-2 horse max but its not worth it. i personally cut my cat off. but im not suggesting nor recommending.

Just buy a magnaflow or the like cat for around $60 and put it up in there, should work fine. If you get CEL's do the Spark plug fouler trick.

get a cheap cat from the parts store, you cannot bypass the sensors. they will throw codes no matter what you do to them, even if it doesnt thro the light. ive cut my cat b4, its not worth the headache, you thought your current noise is bad, trust me you dont want to cut them, its by far worse. you will have no reduced pulsation in your exhaust, your idle speed will drop to the point it barely idles and charging system acts up, and it sounds like crap.

With the universal How will I get the oxygen sensors attached. One before and one after the catalytic converter there are no slots for them in the universal? the hole don't come pre drilled I need access to a welder for that right? that could be a problem. is there a way to cut the cat out shorter enough where the oxygen sensors stay as they are and a universal fits between.

depends on how much pipe you have to work with and how long the cat is. are you clamping or welding?

last time i checked the sensors went on the pipe b4 and after the cats, not on or in them. even if they do, on the magnaflow cat there is a port on the backside of the cat that has a tack on it (i had one i seen it and wondered what it was for...) if you grind the tack off and get the cap loose it looks like a standard bung for an o2 sensor.
