Default Catalytic Converter

Does anyone know where to get an aftermarket Catalytic Converter for my 07 Monte Carlo SS??

Thanks in advance

Lots and lots of options here. Based on your previous posts, Im assuming youre looking to replace a plugged or damaged stock unit / arent looking for a performance upgrade.

Rock Auto has several bolt in aftermarket stock style replacement options (ie full downpipe with cat included). Theyre a bit more expensive up front that the option below, but they make it an easy swap - 2 bolts on each end plus the rear o2.

Most any shop that carries exhaust parts will have a wide selection of universal catalytic converters only (ie cut out OEM and weld in the new one). One online performance shop Ive used a lot is Jegs - theyve got dozens and dozens of options, but even your local muffler shop will have plenty of options. Just be careful not to get one that isn't compliant with your emissions to avoid causing issues (ie dont get a 49 state compliant one if you need a CARB cert, dont buy a pre-obd 2 model as itll trip a code for efficiency). These will initially look a good bit cheaper, but the tradeoff is more labor as they need to be welded in place.
