This is a set of manifolds (headers) with catalyst bypass to fit third generation model, known as the 981 (2012-2016) 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 pair of manifolds with secondary cat bypass (decat). Fitting this part will see a substantial power increase and a little extra noise. Check engine lights may come on once this product is fitted depending on your set-up, typically if this is the only exhaust modification you have made they won't trigger.
