Review on Direct Fit CalCat Carb 82664 Catalytic Converter by Walker Exhaust by Chris Lacasse

Revainrating 5 out of 5

Worked great, screws come loose easily, needs welding

Worked great, fits perfectly. Yes, we had to do some welding on the existing exhaust system. Toyota Corolla is unscrewed from the muffler and exhaust manifold. Just unscrew and take to someone to weld. It took about 20 minutes. to take out the old one. 14mm screws PLEASE purchase a NEW O2 sensor BEFORE attempting to install it. The old one doesn't come out WITHOUT effort. FYI, the new O2 sensor is disconnected under the carpet on the passenger side.

Pros
  • Don't waste too much time
Cons
  • Nothing
