Masata BMW S55 F80 F82 Catless Downpipes for M2 Competition, M3 and M4
Transform the sound and performance of your BMW S55 with the Masata catless downpipes. Engineered for the F80 M3, F82 and F83 M4, and F87 LCI M2 Competition, these decat downpipes deliver maximum flow, sharper turbo response and an aggressive exhaust note. Built from premium 304 stainless steel with a reinforced turbo flange and a unique soft flex section, the Masata S55 downpipe is a proven upgrade that fits like OEM and performs brilliantly on both standard and tuned cars.
Expect serious gains with a Stage 2 tune. When combined with tuning, these S55 catless downpipes have shown increases of 60 to 70 bhp and 70 to 80 lb.ft of torque, alongside faster spool and a deeper, crisper exhaust tone. At Nforcd we have fitted these Masata S55 downpipes on multiple customer cars and our own development vehicles. Fitment is spot on, the quality is excellent and feedback on sound and performance has been consistently positive.

Construction and design
Masata’s S55 downpipes use smooth bends and a one piece layout to decrease turbulence and increase flow without restriction. The flex section mirrors the factory approach to control movement from extreme turbo heat, helping prevent cracking and reducing stress on the turbo flange. The result is a robust, long lasting downpipe that delivers consistent performance and a refined finish.
