CTS Turbo downpipe set for BMW M5 F90/M5C and M8 G15/G16

CTS Turbo downpipes with high-flow catalysts are designed to provide the best possible exhaust gas flow and greater performance potential. They are intended to replace the restrictive factory parts on vehicles with the 4.4 Twin Turbo engine.

The product was developed using modern CAD technology and manufactured for precise fitment in place of the factory parts. It is made from cast T304 stainless steel, hand TIG-welded and welded in a protective atmosphere, with the back side of the weld purged for long-lasting reliability.

The high-flow catalysts improve the sound and character of the S63 engine. Combined with the factory exhaust system, they create a deeper and louder sound, along with more pronounced exhaust pops on downshifts. The sound is more pronounced on upshifts, and it will be even louder with an upgraded exhaust system already installed. With the factory exhaust, the system does not cause unpleasant droning.
