Would'nt the malfunctioning catalytic converter have a negative impact on the performance of the car? I have not noticed any decrease in performance at all just that horrible rattling!
OK, I am just gonna have to take it into a muffler shop...I was just hoping to have something definite to combat the, almost sure, run around and false truths that are always anticipated at most all shops.
I trust you guys (and Gals) totally and that is why I always ask for your opinions and recommendations before I take it anywhere! Thanks,
