VRSF 3"/76mm Cast Catless Decat/De-Cat Downpipes (Down Pipes) for BMW S55 - M3 F80 15-18, M4 F82/F83 15-18, M2 Competition F87 18+ - Brushed SS304 V-Band High Flow Turbo Outlet Cat Delete Race Pipes

Transform the way your S55 breathes with these VRSF 76 mm cast decat pipes in a brushed 304 stainless finish. Designed for the twin turbo BMW M powertrain, this high-flow turbo outlet section replaces the restrictive factory catalysts to cut backpressure, bring boost on earlier, sharpen throttle response and unlock meaningful gains once mapped. Ideal for track and motorsport use where emissions equipment is not required.

We have installed and run these on our own S55 builds at MJ Modifications and customer feedback has been consistently excellent. Fitment is spot on, the cast transitions are super smooth, and the sound is aggressive without drone when paired with the right exhaust setup. If you are chasing reliable performance on an F-series M car, this is the proven upgrade.

Key reasons enthusiasts choose these 76 mm cast decat pipes

• Real world power and torque when calibrated - commonly 20 to 25 whp and 25 to 30 wtq gains on tuned S55 engines
• Cast stainless V-band merge for a seamless, high flow transition from the turbochargers
• True 76 mm bore maintained almost to the outlet for maximum gas velocity compared to necked down alternatives
• Mandrel bent, TIG welded 304 stainless with a durable brushed finish
• Smoother bend radii reduce turbulence and improve turbo efficiency
• Direct fit for both RHD and LHD chassis with no cutting or extra parts required
• Includes high strength Grade 12 mounting hardware
• VRSF lifetime warranty covering defects and fitment

Construction and performance sound

Precision CAD designed cast inlets and tidy TIG welds deliver strength, heat resistance and consistent flow. Freeing the turbo outlet on the S55 means quicker spool, improved transient response and a harder hitting mid range. Expect a deeper, more purposeful note on M3, M4 and M2 Competition applications, with that signature twin turbo rasp under load.

Optional ceramic thermal barrier

Add professional Cerakote high temperature ceramic coating rated to 1800°F to help manage under bonnet heat and reduce radiant temperatures into the engine bay. Pipework carries a lifetime manufacturer warranty. Ceramic coating is warrantied for 1 year due to the nature of the finish.

Vehicle compatibility

• BMW M3 F80 saloon 2015 to 2018
• BMW M4 F82 coupe and F83 convertible 2015 to 2018
