Evolve’s Catless Turbo Downpipes for the S63B44TU engine found in the F10 M5 & F06/F12/F13 M6.

Evolve’s catless turbo downpipes are made from T304 stainless steel and are 3″ in diameter stepping down to 2.5″ to join the front pipes gaining up to 35 BHP and 51 lb.ft torque. They remove the primary cats allowing the turbos to spool up faster providing greater throttle response whilst lowering EGTs (Exhaust Gas Temperatures).

Combined even with the stock exhaust, the performance as well as the sound is transformed without any drone. An ECU Remap is required to prevent a Check Engine Light (CEL).

They fit both RHD and LHD and have 100% fitment.
