The entire exhaust system is made of high-quality materials, in this case it is of course real carbon. The different pipes are made of stainless steel. The DB-Killer is only fixed with a circlip and can be removed at any time. If the exhaust system is used without catalytic converter and dB-Killer, an increase in performance of approx. 1-1.5 HP can be expected. However, this of course has the consequence that the EG-BE of the exhaust goes out. By the way, these data are lasered, engraved or attached to the exhaust by a sticker. It is therefore not necessary to carry papers with you.
The scope of delivery includes the manifold, a suitable intermediate pipe as well as mounting material and of course the rear silencer.
A catalytic converter must be ordered separately. Item no.: 70512CT
