In addition to the "legal", homologated version of the Giannelli Ipersport, we also offer a "racing" version. The simple difference is the manifold without catalytic converter. This supports the gas flow and at certain engine rpm slight increases in performance can be expected.
The disadvantage of this configuration is the missing EG-BE for the manifold. It can happen that the TÜV refuses a sticker, the "race management" demands a demonstration with suitable parts, or even prohibits the continuation of the journey.
