This is a set of manifolds (headers) with 200CPSI catalytic converters to fit second generation model, known as the 987.2 (2009-2012) Boxster and Cayman. This is a high quality, 304 grade stainless steel, TIG welded and guaranteed to be a direct fit replacement. Fitting this part will see a substantial power cand a little extra noise. Great alternative to the catless model if you have concerns about emissions. These units a tune is recommend and still may trigger a check engine light on some vehicle and require 02 spacers.

These catalytic converters are not CARB certified, check local laws if concerned with legality.
