If you know for sure you are going forced induction in the future you will benefit from 3” catalytic converters if you have emissions testing and/or inspection to pass. With a supercharger if that is the route you decide to go catless would be your best option to see the best gains. There are some moderately prices catalytic converters or “HFC” for our cars that are good quality and will last. Why are you Choicing this exhaust set up??
