Borla S-Type Cat-Back™ Exhaust - F80/2 M3 & M4

This stainless steel rear exhaust section replaces the heavy (and restrictive) stock exhaust system on the S55 engine. Shed excess weight and restriction, and get a better sound! You will love the rich, deep sound this tuned system gives your M3 or M4. There's a throaty and purposeful growl at low RPM and at cruise that highlights the six-cylinder engine under the hood.

  • 2.5" pipe diameter from cat-back 
  • Borla guarantees every muffler with a 1,000,000 mile warranty
  • Clamp-on design
  • Round tips 88mm Borla angle cut
