BMW N20 F20 F22 F30 catless downpipe A205P

Stone Exhaust A205P catless downpipe for N20 engines in F20, F22 and F30 chassis - no cats, no compromises. Designed for fast-road or track-day use where backpressure reduction matters.

• Direct bolt-on; reuses OEM hangers and gaskets
• One-piece CNC mandrel bends with flex section to handle thermal expansion
• Turbo flange reinforced with crisscross-overlapping welds for durability
• 3D-scanned from OEM geometry for precise fit - no grinding or shimming
• 2-year UK warranty backed by Stone Exhaust

Not a daily-driver compromise: expect sharper throttle response, quicker spool and a deeper exhaust note. Requires remap.
