Custom Stainless Steel De-Cat/Sport-Cat Downpipe Kit for Mercedes GLC63 AMG, GLC63s AMG , working with M177 DE 40 LA engine with stock power 476-510HP, is the direct P&P replacement for the stock Downpipe.

You can choose between De-Cat Downpipe and a Race Cat Downpipe (100 CPSI / 200 CPSI).

It fits LHD cars only.

Every part of this racing focused downpipe replacement is produced using CNC technology and is fully made out of Acid-Resistant Steel. If you choose a De-Cat Version, which doesn’t include the Catalytic Converter (CAT), you will significantly reduce the back pressure which leads to faster spool, an increase of power and more aggressive exhaust sound. The Race 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!
