Im looking to relace my exhaust system and perhaps add another system to put them on both sides. Any recomendation of good companies and websites that sell them. Any videos/soundclips would be helpful aswell Thanks!
The factory exhaust is better then most aftermarket. you could get a BMW performance exhaust system from your local dealer.
What are tires??? or do you mean Tyres? just ask the people in the TYRE centre they can advise you.
i would recommend supersprint, eisenmann, borla, milltek, active autowerke, dinan, evosport, rogue engineering, madness motorworks, and basically any that use 304 grade stainless steel. google any of those or youtube them for their websites/demonstrations. turner motorsport also sells many of the top exhaust systems.
