It is the ideal GPF-back exhaust upgrade if you want more character, presence and road-friendly refinement from your M5 without touching the catalysts or particulate filters.
Craftsmanship and performance you can feel
Every Milltek system is hand-finished by time-served craftsmen, using type 304 stainless steel throughout the pipework, silencers and hardware. The material is highly resistant to discolouration and built to last. Combined with precision mandrel bends and an optimised bore, you get improved gas flow and a richer, motorsport-inspired soundtrack that remains refined on the motorway.
