Review on 🚗 MagnaFlow 334016 Universal Catalytic Converter 2.5in Inlet/Outlet Diameter, 16in Length - CA Legal CARB Compliant Stainless Steel Replacement (No O2 Sensor) by Jared Winebrenner

I bought a 2.5" full aftermarket exhaust. It fit perfectly, but also had to be cut and welded at your local muffler shop for about $160. Although a T-2 category catalyst is CA compliant only for trucks, this configuration would not be legal for my tiny civilian vehicle. I didn't know about it until the fact left me no choice but to register for the next registration in Washington. Hopefully my experience will help someone else going through the same ordeal.
