Category: Brand: , ,

Description

Unleash the full potential of your 2017+ Audi A4 or A5 with the GCA Performance Audi A4 B9 valved exhaust system — a premium stainless steel and titanium cat-back exhaust engineered for maximum horsepower, torque, and sound on the B9/B9.5 platform. Designed and manufactured by German Car Accessories (GCA), this valved system lets you switch between a refined daily-driver tone and an aggressive performance soundtrack at the touch of a button.

Key Features

  • Valved exhaust technology — electronic valve opens and closes on demand for a quiet cruise or aggressive roar
  • Stainless steel & titanium construction — corrosion-resistant, lightweight, and built for long-term performance
  • Maximum HP & torque gains — reduced backpressure releases power your factory exhaust was holding back
  • Custom options available — email us with special requests for tip finish, sound level, or valve configuration
  • B9/B9.5 platform specific — engineered specifically for 2017+ A4 and A5 to ensure perfect fitment
  • Aggressive exhaust note — deep, throaty tone on open valve; refined and quiet on closed valve for daily driving
