MTC Motorsport BMW M5 M6 F10 F12 Stainless Steel Decat Downpipes for the 4.4 Twin Turbo Engine.
The downpipes are machined from T-304 high-grade stainless steel and are tig welded in house to deliver the best quality.
They will fit the following models:
- BMW M5 F10 2010-2017 575 or 600BHP
- BMW M6 F12 2010-2017 575 or 600BHP
The downpipes will provide a sharper throttle response due to faster spool of the turbo.
They will provide noticeable power gains and a much more aggressive exhaust note which sounds truly amazing.
They produce lower temperatures and less exhaust backpressure due to the relief of the turbocharger.
The cylinder charge is increased which generates maximum performance.
There is also a substantial weight saving in comparison to the factory catalytic converter.
The decats are mandrel-bent for better gas flow and maximum internal size to ensure ultimate performance without the loss of mid-range torque.
We have tested this product and found increases of around 20-25bhp.
Professional installation is recommended as some exhausts sit slightly different from others and can be tight although the feedback we have received from this product is that it is very easy to fit.
We now also sell the 304 stainless steel Lambda Sensor Spacers to prevent the engine light coming on in most cases.
