CTS Turbo BMW S63 F10 M5/M5C & F06/F12/F13 M6/M6C High-Flow CATS

Free up your S63 4.4 twin-turbo with CTS Turbo high-flow cats for the F10 M5/M5 Competition and F06/F12/F13 M6/M6 Competition. Engineered in CAD to drop perfectly into place of the restrictive factory catalytic converters, they are manufactured from cast T304 stainless steel, hand TIG-welded and back-purged for years of reliable service.

Beyond the power, they make the car sound the way it should: a louder, deeper growl with a far more pronounced crackle on downshift, and a confident punch as you bang through all 8 gears on the up-shift. Already running an aftermarket exhaust? It gets even louder.
