Direct-fit catless downpipe for BMW N55 engines with electronic wastegate (EWG) - built for M135i, M235i, 335i, 435i and M2 (2013+). No cutting, no welding, no guesswork.
4.5 inch big-bore flow path cuts back pressure hard, sharpening throttle response and spooling the turbo faster. Full 304 stainless steel, TIG welded, with flanges matching OEM bolt patterns.
Stage 2-ready foundation - pairs cleanly with remaps, intakes and intercoolers
Deeper, more aggressive turbo note under load (not a drone)
Track day or fast road use only - not for road-legal UK registration
A custom ECU tune is essential to run safely and unlock gains.
