Badass BMW X1 35i Flyby Sleeper Downpipe Exhaust Sound

This X1 35i E84 sounds awesome with a downpipe and tune. This is the ultimate sleeper and gaps e90 & e92 M3’s all day long. Current setup on this E84 N55 is FBO plus a Pure Stage 2 turbo upgrade and port injection. Runs 11’s at the track on the weekends and commutes to work during the week.
