MTC Motorsport BMW X3M and X4M F97 F98 chassis S58 Engine Stainless Steel Decat Downpipes

The X3M downpipes are machined from SS304 aircraft grade stainless steel and are tig welded in house
The downpipes will provide a sharper throttle response due to faster spool of the turbo
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.
Mandrel-bent for better gas flow and maximum internal size to ensure ultimate performance without the loss of mid-range torque.
Finished in brushed stainless with gaskets and bolts
These downpipes will fit the following models:

BMW X3M F97 2019+
BMW X4M F98 2019+
We have tested this product and found increases of 30-40bhp on a standard car.

These downpipes fit the stock catback as well as all aftermarket catbacks that match up with the OEM downpipe.

Professional installation is recommended as some exhausts sit slightly different from others and can be tight. You may also need to code out the new PPF filters on some of the newer cars.
