Bmw E46 M3 owner

Hi Guys

My name is Aveshan. I am from Durban and currently drive a 2004 E46 M3.

I have seen some of the cool events held by bmwfanatics and have been told by friends to join the forum.

I have a few questions that I would like answered and hopefully someone can provide some insight:

My car is currently stock I would like to put an AC Schnitzer exhaust system on it does anyone know where I could take my car to have the exhaust fitted in Durban and the if possible an estimate of the cost ?

Would the car become very heavy on fuel with the exhaust system fitted?

I am looking for an exhaust that sounds like the AC Schnitzer exhaust but has the seperate 4 tail pieces and does not have the joined tail piece like the AC Schnitzer exhaust. Any recommendations ?

Thanks
