Evolve BMW S55 3 inch Catless Downpipes for F80 M3, F82/F83 M4 and F87 M2 Competition
Transform your BMW M3, M4 or M2 Competition with the Evolve S55 3 inch catless downpipes. Precision TIG welded in stainless steel with robust cast turbo flanges, these decat downpipes dramatically reduce back pressure to unlock faster turbo spool, sharper throttle response and a deeper, more aggressive exhaust note. Ideal for drivers chasing genuine performance gains and that authentic S55 soundtrack.
We run these on our own S55 cars at Nforcd and our customers consistently report noticeably quicker spool, stronger mid-range punch and a richer exhaust tone. If you are planning Stage 2 tuning, these are a must-have foundation.
