Cast Stainless Steel Downpipes

The CTS Turbo BMW S63 F10 M5/M5C & F06/F12/F13 M6/M6C Downpipes are engineered to maximize exhaust flow, leading to significant power gains. This construction not only enhances power but also transforms the vehicle's auditory signature, producing a deeper, sportier growl with enhanced crackle on downshifts, while remaining subtle during cruising and free of drone when paired with the factory exhaust. Key product details include their design and testing on real-world vehicles, robust T304 stainless steel construction with TIG welding, replacement of the restrictive factory catalytic converter for improved performance, and an enhanced exhaust note. The downpipes are specifically designed for the following models: 2012-2016 F10 BMW M5, 2012-2016 F10 BMW M5 Competition, 2012-2016 F06/12/13 M6, and 2012-2016 F06/12/13 M6 Competition. It is important to note that installation of these downpipes will trigger a check engine light (CEL). To resolve this and ensure optimal performance, proper stage 2 tuning software must be used post-installation.
