Emissions Legality:

Let us address the topic of removing the catalyst, commonly achieved through the utilization of downpipes. Our rigorous testing regimen involved conducting consecutive dyno runs with and without the catalyst, and the observed power gain was significantly smaller than commonly touted, typically around 11 HP. Nevertheless, it is important to acknowledge our shared responsibility towards environmental preservation, as clean air is vital to our well-being. Furthermore, obtaining the necessary emissions certifications without a catalyst is a daunting task and, from a legal standpoint, it is considered an infringement.
