I did bring this up before but didnt get many responses. My catalytic converter is totally screwed, it makes a funny rattling sound like the ceramic crap is loose and rattling i guess. there seems to be more power but i need sum suggestions wether i should get a new cat on there, or just to get it checked. Im unsure wether i melted the temperature sensor too. Story was that i overheated the cat at the race track, didnt care and kept going, light went off, but funny sounds happened. theres no leaks just the annoying sound
HELP ME
