4 inch turbo outlet race pipe for BMW N55 EWG F series - M135i, M235i, M2, 335i, 435i

Give your N55-powered BMW the response and soundtrack it deserves with this 4 inch de-cat front pipe engineered for the electronic wastegate F series platform. Built in premium 304 stainless with smooth mandrel bends and precision CNC flanges, this high flow turbo outlet frees up exhaust velocity, helps the turbocharger spool sooner, and unleashes a deeper, more aggressive tone. It is a proven upgrade for drivers who want real gains once mapped, sharper throttle feel, and a purposeful, motorsport-inspired sound.

At MJ Modifications we have installed this unit on our own development cars as well as countless customer builds. Fitment has been consistently excellent and feedback on performance, sound quality and finish has been outstanding. If you are chasing quicker spool, stronger mid-range and a louder, richer exhaust note, this is the go-to N55 EWG front pipe.

Key reasons enthusiasts choose this N55 EWG 4 inch de-cat pipe

• Massive 4 inch primary section for maximum gas flow on the EWG N55 platform
• 304 grade stainless steel - hand crafted and TIG welded for strength and longevity
• Mandrel-bent tubing for smooth radius transitions and minimal turbulence
• CNC machined stainless flanges for an accurate, leak-free seal
• Noticeable reduction in back pressure for faster turbo response and improved drivability
• Typical power increase when mapped - ideal for Stage 2 style calibrations
• Amplifies turbo whistle and delivers a deeper, more aggressive exhaust character
• Brushed stainless finish that looks great and resists corrosion
• Manufacturer lifetime warranty on the pipe

Prefer a sports catalyst option Instead of a test pipe configuration, a 200 cell high flow catted version is also available for those seeking reduced odour while retaining excellent flow.

Optional thermal barrier coating

Upgrade with high temperature ceramic coating rated to 1800 Fahrenheit. This heat management layer helps retain energy inside the pipe, assisting with under-bonnet temperature control which can support intake air temperature reduction. Downpipe carries a lifetime warranty from the manufacturer and the coating carries a 1 year warranty. Catted versions carry a 1 year warranty.
