Milltek Particulate Filter-Back Axle-Back Exhaust System with JET-115 Carbon Fibre Tips for BMW G82 M4 & M4 Competition (2020+) S58 3.0 Twin Turbo OPF/GPF Only

Transform the sound and finish of your BMW M4 with a premium UK-built rear section engineered for OPF-GPF models, complete with quad JET-115 carbon fibre tailpipes.

Give your G82 M4 or M4 Competition the soundtrack it deserves. This performance rear exhaust section has been developed specifically to work alongside the factory petrol particulate filters, delivering a deeper, richer tone with a sharper, motorsport-inspired character while keeping everyday refinement intact. The JET-115 carbon finishers add a crisp, aggressive look that perfectly complements the M rear bumper.

Why enthusiasts choose this rear section

• Specifically tuned for OPF-GPF cars - enhances tone and character while maintaining cabin comfort
• Constructed from high-grade T304 stainless steel for long-term durability and corrosion resistance
• Mandrel-bent pipework for smooth, consistent gas flow and responsive driveability
• Carefully increased bore over stock to help the S58 breathe without sacrificing mid-range torque
• JET-115 real carbon fibre quad tips for a premium motorsport appearance
• Designed, developed and hand-finished in the UK by expert craftsmen
• Refined acoustic development to minimise drone and unwanted resonance

The sound your S58 straight-six should have

On the 3.0 twin turbo S58 platform, this rear section unlocks a deeper idle, a fuller mid-range and a cleaner, crisper note under load. It keeps motorway cruising civilised and comfortable, but comes alive when you ask for it. It is the ideal balance for road-driven M cars that still want a genuine performance tone.
