which catalytic converter ?

There were some postings found in " search" regarding the cat.converters. I will probably get a replacement for the current stock cat conv. I want to keep the jeep as quiet as possible , while not spending a suggested $400 for OEM . Can anyone provide me with sources/ types /prices for a new cat conv ? What is a catback all about ? Why would someone install a cat back ? Is it performance ( HP ) related ? Is it as quiet as OEM ? I found an ad for a replacement cat conv for approx $ 35- $50 , but the size was very small ( 19 inches , I believe ) and I question its noise level ?

Re: which catalytic converter ?

Generic fit catalytic converters can typically be had for the $40-$50 range. Sometimes you will need to use an adapter, as they are not "direct fit". Depends on the application, I think. Take your old one with you when you get the new one.

19 inches long seems about right -- they're not too big. Exhaust noise level will typically be a function of the muffler, not the cat.

Catbacks, as I understand it, are typically used to supposedly add horsepower. They will sometimes have a "throaty" sound. You can also get a "highflow cat", but I don't know how restrictive a standard cat is to start with.

Why do you want to replace the stock one? Are you looking for more power?

Good luck

Re: which catalytic converter ?

Cat back is an exhaust system that replaces everything behind the catalytic converter, as in: from the 'cat back'. Most performance exhaust systems will be a little bit louder the the factory system. You can get aftermarket catalytic converters much cheaper then from the dealer, just go to any auto parts place. There are even hi-flo cats, and even they are cheaper the OEM units. It is not the cats job to make the exhaust quiet, that's the mufflers job.

The cat is rattling . I think that the honeycomb inside is deterioting after the 7 years that I have it . I hope to get an idea of replacement prices / ideas . My goal is to keep the Jeep quiet . A friend had a new hi-flo cat installed and the car is louder .
