BMW M3 F80 / M4 F82 / M2C F87 Valvetronic Catback Double Mid-Pipe Titanium Exhaust System

Engineered for BMW M3 F80, M4 F82/F83, and M2 Competition F87 owners, this Valvetronic Catback Double Mid-Pipe Titanium Exhaust System ships with its own electronic control box and wireless remote. Manufactured in Europe and quality-controlled by BYC Performance, it bolts directly to the OEM mid-pipe v-band on all S55-engined M3/M4/M2C trims.

The double mid-pipe + titanium combination delivers the most aggressive sound character in the BYC catalog — twin parallel flow paths produce a fuller, more aggressive note while titanium construction adds a sharp metallic tone. The system is significantly lighter than the stainless version. 90 mm twin exit tips are customer-selectable in Glossy Black Stainless, Polished Stainless, Matte Carbon Fiber, or Glossy Carbon Fiber.
