Question Exhaust without downpipes

I've seen people having a lot of check engine light problems after installing downpipes.
My question is, will the car still sound nice if I only install the exhaust (Akrapovic or Meisterschaft).

Sure it will sound great. Down pipes will just add to the volume and power increase by means of less air restriction.

Would it affect the fuel consumption in a bad way?

Do we really care that much about gas mileage for a car that costs this much?

Lmfaoooo good point sorry I'm a. New M6 owner but I don't believe that more air flowing would effect mpg at all if anything it should improve it

Last of my annoying questions: Should I get cats on the downpipes? I've heard it fixes a lot if problems such as check engine light, fuel smell, emission check

I would think to leave the cats on, especially in Canada or Kalifornia SSR. you don't need the KGB all over you.
