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
PLEASE NOTE:
The use of de-cats, sports cats are for off road/motorsport use only. Using these parts would inhibit your vehicle from passing a MOT test.
Only EC type-approved components are legal and fit for road use.
My Performance Parts / TS Parts Ltd accepts no responsibility for the use of parts which remove emissions devices on the public highway. It is the customers responsibility to ensure that all local laws are adhered to within their home state/country.
