These high tech German manufactured systems are tested comprehensively for flow characteristics, flow rate, thermal stress, cracking, and longevity. The end result exhibits a strong, linear, firing-order dominated flat 6 Porsche sound. High quality inner packing and outer shell design also dampens and eliminates unwanted frequencies to ensure that there is no resonance or drone in the cabin. Each of our exhaust systems have been extensively tested on both a chassis and engine dyno as well as logged thousands of miles on both the street and at the track. All of this research, development and testing ensures maximum horsepower gains throughout a broad power band, while maintaining reasonable sound levels for street use._x000B__x000B_We strongly suggest replacing worn gaskets and hardware with our pre-packaged installation kits._x000B__x000B_Like all European Vehicles, FVD parts are TUV approved. What is TUV approval you ask? Basically, German-registered road vehicles may not be operated on public roads without a certificate from the TUV. Also, all modifications must be approved, from installing tires of a different size to materials used in nuts and bolts. TUV's safety guidelines are among the strictest in the world, and getting a road permit for thoroughly customized vehicles borders on the impossible._x000B_FVD Exhaust Systems Carry A 2 Year Warranty!
