However, if you have purchased a warranty, it can be transferred to the software upgrade at no additional charge!!    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 2%. 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.    About Steve Dinan:  With an illustrious career spanning over four decades, Steve Dinan stands as an authority in streetcar turbo tuning.
