Remus rear section upgrade for BMW G80 M3 Competition

Turn up the excitement on your BMW M3 G80 with this Remus valved rear section. Designed to unleash a sharper, track-focused soundtrack while keeping everyday usability, this precision-built system is crafted from premium stainless with a bead-blasted finish and quad 102 mm chrome trims for a clean, motorsport look.

Hand-built in Austria to an exceptional standard, this performance rear box reduces restriction to help the S58 breathe more freely, delivers a weight-saving design, and retains the factory electronic flap control for seamless integration with your drive modes.

Why choose this Remus rear exhaust

  • Full stainless construction with bead-blasted surface for durability
  • Lower restriction layout to aid response and performance
  • Lightweight design compared to bulky factory hardware
  • Engineered for a precise, factory-level fit on OE mounting points
  • Austrian hand craftsmanship and premium finish quality
  • Quad 102 mm angle-cut, rolled-lip chrome tips for an aggressive appearance
  • Retains original electronic valve operation via the car’s controls
