The downpipe and flange are machined from SS304 aircraft-grade stainless steel and are tig welded in house to deliver the best quality. The MTC F90 downpipe is made of 3" stainless pipe straight out of the turbo providing a sharper throttle response due to faster spool of the turbo.

 This downpipe will provide noticeable power gains and a much more aggressive exhaust note which sounds truly amazing. Feedback from customers is that the downpipe crackles and bangs but is quiet on the motorway which is perfect. It produces lower temperatures and less exhaust backpressure due to the relief of the turbocharger. The cylinder charge is increased which contributes to maximum performance.

There is also a substantial weight saving in comparison to the factory catalytic converter.

The decat is 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 40-50bhp on test vehicles however, it does have the capability of increasing horsepower by 150-180bhp once your car has a stage 2 map.

The standard V band clamp works perfectly onto the turbo and the middle section too.

Will fit the following models perfectly: 

- F90 chassis M5 2018-

On the newer BMW models they have a PPF filter which will probably need to be coded out by a tuner so it doesn't show a fault. Speak to your tuner about this if you are not sure as the earlier models didn’t have the PPF.
