CTS Turbo BMW S58 F97/G01 X3M/X3MC & F98/G02 X4M/X4MC Downpipes Without Heat Wrap

Unlock the 3.0L twin-turbo in your BMW X3M or X4M with the CTS Turbo downpipes for the F97/G01 X3M and F98/G02 X4M, including Competition models. Built to drop in where the restrictive factory catalytic converters sit, they maximize exhaust flow for the highest power gains — and they transform the soundtrack.

Sound and performance

On the factory exhaust they bring a louder, deeper growl with a much more pronounced crackle on downshift and a confident punch as you row through all 8 gears. Running an aftermarket exhaust already? It gets even louder.
