Performance Muffler did an awesome job changing my catalytic converter on my 1998 Ford Crown Victoria. I was quoted $480 to replace my passenger side Cat (P0420).
Come to find out my car was previously modified and had only a single cat. I returned and only had to pay $280. These guys are very honest and do great work.
They could have easily ripped me off and charged me for the double Cat.
I will most definitely be coming to Performance Muffler again and telling all my friends!!!
