Redstar BMW F80 M3/M4 Downpipes
Pairs well with
Transform the exhaust performance of your BMW M3 F80, M4 F82 and F83, and M2 F22/F87 Competition with Redstar performance exhaust downpipes engineered for the 3.0 S55 twin turbo engine. These downpipes replace the restrictive factory catalytic converters within the downpipe section to free up exhaust flow for your S55-powered M car.
Expect sharper throttle response, quicker turbo spool, and meaningful power gains from the reduced backpressure and flow-optimised transitions. Optionally, Redstar OEM-style heat shielding uses motorsport-inspired construction to cut radiant heat by up to 80 percent, helping lower under-bonnet temperatures and supporting turbo longevity while enriching the exhaust character with a more assertive note.
Built for demanding use, every Redstar downpipe is hand made from premium 2.0mm wall 304L stainless steel, 100 percent TIG welded and back purged, and fitted with OEM-spec 304L stainless steel flanges plus factory-style brackets and mounts. The result is a true 100 percent bolt-on fit that is LHD/RHD compliant and integrates seamlessly with the original system. Choose Redstar downpipes for uncompromising quality, durability, and a decisive step up in performance and sound.
