Other Products ｜BMW M5 | M8 F90 F91 F92 F93 Primary & Secondary Downpipes Full Set

Upgrade your BMW M5 or M8 with the complete Project Gamma Primary and Secondary Downpipes package, engineered for maximum exhaust flow, improved turbo response, and a more aggressive exhaust tone.
Designed specifically for the BMW F90 M5 and F91/F92/F93 M8 platform, this full downpipe set replaces both the primary and secondary factory downpipes for a complete performance exhaust upgrade. Project Gamma downpipes feature a 4” construction, stainless steel V-band to pipe transitions, and precision CNC-machined fitment for a proper installation.
Unlike restrictive factory components, these downpipes are designed to reduce exhaust backpressure and allow the S63 engine to breathe more efficiently. When paired with the proper tune, this setup can deliver major power gains, sharper throttle response, reduced turbo lag, and a deeper, more exotic exhaust note.
Each set is handcrafted from 304 stainless steel for excellent durability and corrosion resistance. Available in polished finish or ceramic coating for additional heat protection.
