It also comes with an extra o2 sensor bung and plug so you can run a wideband air:fuel ratio gauge.  ALL DOWNPIPES FEATURE A 200 Cell High Flow Catalytic Converter.

 Product Reviews

  1. fit and finish are superb

    Posted by on

    Installed this downpipe in place of another aftermarket catless downpipe. First off this downpipe is heavy guage material. Excellent craftsmanship. There are no marks left by bendnder. . Welds are very nice. Gasket was included with it and pipe fit with no extra fitting and clearance was perfect. Pipe sounds good and waste gate operates much better with no turbo creep. Tune has not been completed as of yet . But I am pleased with my purchase.
