NOT ROAD LEGAL
As fitted to our own F10 M5 'The Great White', Evolve are pleased to offer our catless turbo downpipes for the S63B44TU engine found in the F10 M5 & F06/F12/F13 M6
Our 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 turbo's 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 or a Delete-R Module are required to prevent a Check Engine Light (CEL). You can also combine with an Awron Gauge with Valve Control to give you control over the volume to suit your mood.
They fit both RHD and LHD and have 100% fitment.
