I get the same problem with these little sooty deposits on the back of the car I put it down having the bigger exhaust pipes compared to the OEM pea shooters and putting your foot down it just has a bigger hole to spit more **** out of.. But I could be wrong..

I remember having the same issue with OEM tail pipes thou it wasn't as bad

I must admit that I didn't have the OEM exhaust on the car for long as I didn't like the back box that hangs in the middle so I probably didn't notice it that much but I do with the BCS exhaust but a good clean and its soon gone it just makes you clean it more often :D
 
Completely 100% normal on the TFSI engine my LCR smoked like a diesel (100cel cat)

If you watch WTCC videos from 2010-onwards the Leon's with TFSI engines smoke terribly
