CTS Turbo downpipe set for BMW X5M/X6M F85/F86 S63

The CTS Turbo race downpipe set for the BMW F85 X5M and BMW F86 X6M with the powerful S63 engine is designed for the best possible exhaust gas flow and greater potential for increased performance. The factory components restrict exhaust system flow and sound.

The product was designed using the latest CAD technology and is manufactured as a direct replacement for the restrictive factory catalytic converters. The race pipes are made from high-quality 304-grade stainless steel, hand TIG-welded and welded in a protective atmosphere, ensuring long-term reliable operation.

The set unlocks the performance of the S63 4.4 l Twin Turbo engine, while the high-flow catalytic converters provide a more pronounced sound. Combined with the factory exhaust system, the vehicle produces a louder and deeper growl, along with considerably more pronounced exhaust pops when downshifting. When upshifting, the sound is more pronounced when changing through all 8 gears. With an additional sports exhaust system, the sound will be even louder.
