CTS Turbo RACE DOWNPIPE SET for BMW F85 X5M S63 & BMW F86 X6M S63 (2014-2019)

Free your S63 from the restrictive factory catalytic converters with this CTS Turbo race downpipe set, engineered for the F85 BMW X5M and F86 BMW X6M. These high-flow race pipes drop straight into place where the choked OEM cats once sat, maximizing exhaust flow so your 4.4L twin-turbo V8 finally breathes the way it should.

Sound and performance

Paired with the factory exhaust, expect a louder, deeper growl with a far more pronounced crackle on downshift and a confident punch as you bang through all 8 gears. Already running an aftermarket exhaust? It gets even louder. This is uncompromising power with the soundtrack to match.
