M178 Mercedes-AMG De-Cat/Sport-Cat Downpipe GT/GT S/GT C/GT R C190
200 CPSI
Custom Downpipe Kit for i.a. Mercedes-AMG GT/GT S/GT C/GT R C190 with 4.0L M178 engine unit and the stock power of 456, 469/503, 515/550/577hp.
Every part of this racing focused downpipe replacement is produced using CNC technology and is fully made out of Acid-Resistant 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 Sport Cat version also offers huge flow improvement over the stock catalyst, which is the cause of very significant flow resistance. 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 MuchBoost downpipe is optimized for minimization of variances in cross section area in order to get smooth exhaust gas flow and top performance.
Because a downpipe connects a turbocharger and the catback exhaust, its upgrade is often required for the upgraded turbo to unleash its full power. This upgrade ensures your turbo’s potential is not wasted, it is also a great choice cost-wise!
