F90 M5 F91 F92 F93 M8 4.4T S63 Twin-turbocharged V8 2018+ Catless Downpipe

F90-04

Every part of this racing focused downpipe replacement is produced using CNC technology and is fully made out of SUS304 Steel. It doesn’t include the Catalytic Converter (CAT) and thereby significantly reduces the back pressure which leads to faster spool, an increase of power and more aggressive exhaust sound. The bigger the diameter of the downpipe, the easier and quicker the turbocharger is able to lead off the exhaust gas. The design of the GotTuned downpipe is optimized for minimization of variances in cross section area in order to get smooth exhaust gas flow and top performance.
