The MagnaFlow Cat-Back Exhaust for your 2004-2010 645Ci or 650i not only offers dyno-proven gains and superior fitment, it also makes your E6X sound the way it should've from the factory.
Most BMWs sound nice from the factory, but they're designed to have a more subtle tone for the average BMW owner, so there's only a whisper of the available performance. MagnaFlow exhausts cure that problem with wide-open performance mufflers that offer a moderately aggressive sound. The smooth, deep tone is suitable for mild-mannered street cars driving around town, yet it opens up nicely under wide-open throttle to have you smiling all the way to the rev limiter.
MagnaFlow Cat-Back Exhausts are constructed of 100% polished stainless steel. The mufflers are lap-joint welded for solid construction and rugged reliability even in the most extreme conditions, and they feature a free-flowing, straight-through perforated stainless steel core, stainless steel mesh wrap, and acoustical fiber fill to deliver the performance and sound your car deserves.
Each MagnaFlow exhaust is designed to provide years of trouble-free performance with better-than-stock looks, plus a lifetime warranty to back it all up. Plus, the MagnaFlow Cat-Back is significantly lighter than the factory parts, so it doesn't just look beautiful and sound great - it improves handling as well.
