Exhaust Install Kits for BMW 3 Series E46 (1999-2005)

If you are performing work that necessitates the removal of the exhaust or installing a performance aftermarket system, these kits will help you get the job done sooner. Exhaust hangers, bolts, and gaskets stand up to years of abuse from engine heat and the elements, they do not, however, withstand removal and installation very well. Vehicle specific kits ensure that you will have all of the necessary hardware for your specific series and model.
