hey guys, i have a 182 with a standard system, recently, think my cat fell off and was scraping the floor with it and it was so loud. Had it welded back on and he said my whole system was quite rotted and needed a new one quite soon. My question is, what do i need for a whole system? What joins on to what? i am a complete noob with exhaust systems so sorry if i sound stupid. I rang Renault and they wanted nearly £2000 for parts thanks in advance!!
