For F22 M235i owners chasing a sharper, more purposeful rear end without ditching valve control or daily drivability - this is the quad-silencer upgrade that actually delivers.
F22-specific fit: designed for the N55-powered M235i chassis; no spacers, no trimming, no guesswork
Quad-exit OEM+ look: twin 90mm Evo tailpipes with AC Schnitzer engraving - clean, aggressive, track-day ready but still civil on the school run
Valve-compatible: retains full factory exhaust valve operation and ECU mapping - no coding, no adaptors, no compromises
Suitable for fast road, track day and daily driver use - not a decat, not a race-only item, not a show-car-only prop
