These large bore downpipes are larger in diameter than the factory items, allowing exhaust gases to exit the engine more freely and improving efficiency. With the catalysts removed, they offer the maximum power gain with no restriction to gas flow on the F80 M3 and F82 M4.
Please note: Designed to fit with the Milltek cat-back system only. This de-cat product is for off-road/motorsport use only and requires a Stage 2 ECU remap.
