Milltek Sport's GPF-back exhaust for the OPF\/GPF-equipped X3M\/X4M replaces everything from the gasoline particulate filter rearward, engineered to deliver genuine gains in flow, sound, and weight over the factory system while retaining the OPF\/GPF unit itself for continued emissions compliance.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eConstructed from T-304 stainless steel throughout, this system is built to outlast the car itself, resisting the corrosion that eventually catches up with mild steel factory systems, especially through wet European winters. Milltek's own sound engineers spend considerable time tuning each system's resonance and tone, striking a genuine balance between a purposeful, sporting character and everyday drivability, avoiding the drone that can plague poorly engineered aftermarket systems on a long motorway drive, a genuine consideration given the size and weight of this performance SUV\/coupe pairing.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePlease select your exhaust tip finish at checkout:\u003c\/strong\u003e Polished, Cerakote Black, Brushed Titanium, Burnt Titanium, or Carbon Fibre.
