Hello,
I am new to this forum, but have been a BMWCAA member for over 12 years. Anyway, I was driving home last night in my e30 and I hit a fender (a car fender was laying in the road) and it ripped the Aluminum cover off my Catalytic convertor. The motor is an M42 and the car is a
318is. My question is: Is it do any harm to run the car without the cover/shield on the cat? I am unclear as to what this thing does on the cat. Thanks for your help.Ben
