Exhaust and Service Advice

Good day all

I've had my E90 320D now for about 6 months and I had enough of the Droopy Tail Pipe. I was wondering if anyone can refer me to a good exhaust place in Pretoria to assist me with getting a twin tips fitted.

My car is also due for a service soon and would like to hear some recommendations from fellow fanatics about service guys we can trust in Pretoria. I Don't like the stealers as for them your car is just a number, I prefer a person who does this out of passion and would want you to return to him because he did a good job.

Thanks in advance
