Yes, changing your catalytic converter can increase the sound of your vehicle's exhaust. This is because aftermarket catalytic converters may have different designs or less restrictive flow characteristics compared to the factory part, which can lead to a louder and more aggressive exhaust note. However, the extent of the change in sound will depend on the specific type of catalytic converter installed and the overall exhaust system configuration.

A knocking sound from a bad catalytic converter often resembles a rattling or metallic clanging noise, especially when accelerating or idling. This sound can occur due to internal components, such as the catalyst substrate, breaking loose or becoming damaged. Additionally, if the converter is clogged, it may produce a more pronounced thumping sound as exhaust gases struggle to pass through. Overall, any unusual noise from the catalytic converter warrants immediate inspection to avoid further engine damage.
Usually a sputtering muffler means that a new catalytic converter is needed. The sputtering sound is the car misfiring.
