BMW M2 Competition F87 S55 downpipes, Milltek large bore with 2x200 CPSI sports cats

Direct-fit downpipes for the BMW M2 Competition F87 with S55 engine. Replaces restrictive OEM primary cats and OPF/GPF to reduce back pressure, sharpen throttle response and improve turbo spool.

• 2 x 200 CPSI high flow sports cats: Balanced flow, minimal drone, aggressive tone with a Milltek Sport cat-back
• T304 stainless steel: UK-made, non-magnetic, corrosion-resistant, lifetime durability
• Large bore, mandrel-bent pipework: Optimised gas flow without sacrificing mid-range torque or daily drivability
• Requires Milltek Sport cat-back: Not a standalone fitment; not for road use where OPF/GPF removal is illegal

Professional installation and ECU remap recommended. Track day or fast road use only.
