Milltek Sport's GPF-back exhaust for the OPF\/GPF-equipped M3\/M4 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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePlease select your exhaust tip finish at checkout:\u003c\/strong\u003e GT-115 Polished, GT-115 Cerakote Black, GT-115 Titanium, GT-115 Burnt Titanium, or the distinctive JET-115 Carbon finish.
