Review on πŸš— Dorman 674-889 Catalytic Converter & Integrated Exhaust Manifold for Chevrolet, Pontiac, Saturn Models - Non-CARB Compliant by Brent Borseth

Revainrating 5 out of 5

Fits great, no modifications needed

Installed on a 2008 Pontiac G6 2.4L. Fits great, no modifications necessary. The power limit returned and the sluggish acceleration was gone. FYI GM has extended the catalytic converter warranty to 10 years or 120,000 miles. The dealer wanted $999 for that part alone because I had $136,000. I would suggest an E7 star socket, ratchet U link adapters and an O2 sensor socket.

Pros
  • Handy thing
Cons
  • I have no complaints about it, everything is fine
