I just bought the complete exhaust system from Top End Performance (http://www.racetep.com/bmwmainframe.html) It included the header/gasket/high flow cat/muffler/tip/O2 bung. I have decided to keep the car smog legal so I need to sell it. It will fit all M10 engined cars including the 318i. It is still in the box. It lists for 384.00 plus shipping and I am asking 340.00 shipped (to lower 48). Thanks
Bob
