BMW M5 F10 / M6 F06 Valvetronic Catback Stainless Steel Exhaust System

Engineered for BMW M5 F10 and M6 F06 Gran Coupé owners, this Valvetronic Catback Stainless Steel Exhaust System ships with its own electronic control box and wireless remote — valve management is integrated during installation and afterward operated via the included remote. Manufactured in Europe and quality-controlled by BYC Performance, this system bolts directly to the F10/F06 mid-pipe v-band.

The F10 M5 + F06 M6 share the same S63B44T2 4.4L V8 biturbo (560-575 hp) and identical catback geometry. The Valvetronic catback replaces the OEM muffler; with the valve closed it delivers a daily-friendly OEM+ sound, and with the valve open it produces a tonal V8 biturbo track tone. T304 stainless steel construction ensures lifetime durability.

Stainless vs. Titanium — This Is Stainless

This product is the T304 stainless steel variant:

• T304 Stainless Steel (this product): Durable, deeper sound tone, lifetime rust-resistance, value pricing
• Titanium: Noticeably lighter, sharper metallic note, heat-tint finish, higher cost
• For weight reduction & premium aesthetic: titanium preferred
• This product is the daily-driving-oriented stainless variant with a deeper V8 biturbo character
