Wagner Tuning BMW N20/N20B20 2.0T Hi-Flow Catted Downpipe (200 Cell) Turbo Front Pipe - F20 F21 F22 F30 F31 F34 F32 F33 - 125i 220i 320i 328i 428i xDrive - SS304 Sport Cat Exhaust Upgrade Stage 2 OE 18327645666

High-flow sports cat turbo front pipe for BMW F-series 2.0 petrol turbo N20

Unlock sharper throttle response, stronger mid-range pull and smoother spool with this Wagner Tuning upgrade. Crafted from premium 1.4301 stainless steel (SS304), this performance front pipe with a 200 cpi sports catalyst is a direct bolt-on replacement that reduces exhaust back pressure and lowers thermal load on the turbocharger for reliable, repeatable gains.

We fit these on customer builds and our own cars at MJ Modifications. Fitment is spot on, the quality is superb and feedback has been consistently positive for drivability, durability and flow.
