Will a cat converter from a v-6 chevy, do the same job in a toyota camry? It's a 4 cylinder..

It should work, the only issue would be if you live in Kalifornia. There the converter has to be approved for use with Fruits and Nuts.

It will work, but like "F o R" said, California won't like it if you live there.

We get questions like this ALL the time- "can I make used parts fit that are not actually for my car?" People do this because new parts cost so much- it is understandable- BUT- did you not understand when you bought this 21st Century Marvel Car that it would cost as much as a nuclear submarine to repair and maintain? Do you get it now? Do you ALL get that the car industry here in the 21st Century is screwing us all over with super-complicated machines that don't do anything more than a 1935 Dodge Sedan did in its day? Move your ass down the road? omg

blues....Point well said. If we insist upon buying motor vehicles which have way to many distracting "bells and whistles" We will continue to accept the fact that driving and maintaining a motor vehicle today is left up to something/someone else. Who is ultimately going to have to pay for all this technology???......yup....you and me. I will continue to restore this 1966 Ford Galaxy....until the fenders fall off. Regarding CATs....New(Correct) parts are a LOT DIFFERENT than old incorrect parts. The CAT on most vehicles has a life expectancy of approx. 80-100,000 miles.

If the pipes on the Chevy are the same diameter as the Camry, simply cut off the old Camry cat pipes and re-weld them on to the Chevy cat. If the Chevy cat is longer or shorter, you will have to shorten the pipes accordingly. I have made cats like that before. Works great especially if the flanges have any amount of pitch to them.

Well, I AM in southern California... :o( And, the car I'm gonna try to cause lower parts per bizillion, into the air, is a friend's, who can barely keep up on his rent. This is why I'm in this spot. I know I can modify the cat to fit.. But it's supposed to get to a certain heat, while running, right? This is what causes the extra burned exhaust gases to be better burned, right? I would hate to do this, and have it fail the test by just a few parts per million, if you get my drift.. life expectancy of approx. 80-100,000 miles. Wow. That's nowhere near long enough if you ask me. I appreciate all the input. Thank you
