I am selling my performance exhaust kit off my 2008 335i coupe. I traded the car in so no need to keep it. It fits sedan coupe and convertibles. the part number is 18102208799. It was installed in the car at 28k miles and and taken off at 46k miles. I am asking $900 and I'll cover the shipping. That's half the price of new plus shipping. It is in perfect condition. boostedmotorwerkes at gmail dot com.
