"Getting the vehicle to pass smog was easy after having the catalytic converter installed. The hardest part of this whole repair was finding a shop to do the installation. A few calls and a trip across town and the install was completed in one day. No additional parts were needed and that was good on the budget." posted by: sidekick on January 30, 2014
