    D3321 - Doug's Headers for GM Passenger Cars is rated 3.0 out of 5 by 1.
    Rated 3 out of 5 by from They are OK The overall construction and quality are OK, but I am very disappointed that these do not come with an O2 sensor bung installed. It's not like an O2 sensor is uncommon. Every care since the mid 80's has one. For the price it would have been nice to have the feature so I wouldn't have to screw up the finish to properly install one for my injection system. May be returning them and shopping for an alternate.
