evocarlos hello and welcome if your removing the pre cat thats great 🙂 if your removing the main cat then i hope you know a good mot tester 🙂
corsaZ22se hello there. as carl said, pre cat removal is easy, just remove down pipe and drill/grind pre cat from it. but as for main cat you need it for mot, 200cpi cats can be fitted any less and you also need to move 2nd lambda sensor out of gas flow.
