LOUD BMW M6 Exhaust V10 Cold Start 

Here is a cold start of my 2007 BMW M6 with the S85 V10. Exhaust is stock headers, stock primary cats, deleted secondary cats, deleted resonator, stainless X-pipe, to de-packed factory mufflers. The mufflers are de-packed meaning we cut open the factory mufflers, pulled out the fiberglass packing and kept the standard baffles. This gives a factory fit and finish but sounds 100x better.
