: All though I have been stalling on replacing my cat, the time has come to finally change it. I know OE cats are really expensive, but if they will last twice as long it is okay with me. A lot of parts people have been pushing DEC cats. What should I go with?

Get a OEM converter. I bought a aftermarket converter on my 735I and it sounded like a Chevrolet pickup with a six cylinder after I put it in. I couldn't stand the way it sounded so I took it off. Now that $500 converter is sitting in the backyard gathering rust after a weeks use.
