BMW 123d E81 cat-back exhaust, Milltek Sport T304 stainless steel

Direct-fit cat-back for the BMW 123d E81 3-door (2007 onwards). No cutting, no welding - just bolt-on refinement for fast road or track day use.

• Full T304 stainless steel construction: pipework, silencers and hardware
• Mandrel-bent for improved flow and throttle response, without sacrificing mid-range torque
• Engineered in the UK to eliminate drone and cabin resonance
• Crisp, sporty tone - not shouty, not droney, just properly sorted
