I went from one place telling me it's my front catalytic converter and I should replace all three cause one goes bad they all will for $2500 to Ken's Muffler using their expertise finding its actually the rear cat and universal converter installed for $250. Talk about great news. Its scares me how other mechanics can just steal from you but Ken s Muffler are honest, reliable and go the extra mile to really find out what's wrong. I was skeptical and they answered ALOT of questions for me patiently. Thanks so much.
