Fabspeed BMW F1x M5/M6 Sport Cat Primary Catbypass Pipes

Eliminate the heavy and restrictive factory catalytic converters with straight-pipe, high flowing stainless steel downpipes for maximum power and an exhilarating sound.

Fits all BMW F12 / F13 M6 vehicles (2012+)

Replaces the restrictive factory catalytic converters with a straight-through “straight-pipe” design for maximum power, increased throttle response, and an aggressive exhaust sound

Constructed out of T304L stainless steel with CNC machined flanges and laser cut brackets

Includes two downpipes, labeled left side and right side for easy installation, and hardware

NOTE: Catbypass downpipes are recommended for track or off-road use only.
Please also bear in mind that this system does not include catalytic converters, so the Check Engine Light (CEL) will most likely be triggered. This is not an indication of any actual issue with the engine, and does not prevent normal vehicle operation.
