Porsche 987.1 Boxster & Cayman Decat Manifolds

19 (30 In Production)

This is a set of manifolds (headers) with catalyst bypass to fit generation 1 987 Boxster and Cayman. After the installation of this product the emission light might come on your dash. To remove it you might need to install the lambda sensor extensions from your existing cat. This is a high quality, 304 grade stainless steel manifold with secondary cat bypass (decat). It is road legal as the 987 has two pairs of cats and this piece only removes 1, thus in conjunction with OE it will pass MOT (although it is ideal for track use). Fitting this part will see a substantial power increase and a little extra noise.

Primary Diameter = Primary External Diameter 45mm 

Collectors Diameter = Collector External Diameter 54mm

The following video is from a trade customer of ours and details the installation and sound of these manifolds-
