MTC Motorsport – BMW X5M F85 3″ Decat Downpipes X6M

MTC Motorsport BMW X5M X6M F85/F86 Stainless Steel Decat Downpipes for the 4.4 Twin Turbo S63R N63N 575bhp Engine

The X5M downpipes are machined from T-304 high-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

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:

X5M F85 4.4 Twin Turbo

X6M F86 4.4 Twin Turbo

We have tested this product and found increases of 30-40bhp.

Professional installation is recommended as some exhausts sit slightly different from others and can be tight.

When installing you don’t need to use the standard heat shields as there are no cats to generate any heat, it’s just flowing straight through. This can be quite difficult and hard to line back up so we don’t recommend re-fitting these.

We also recommend purchasing a Lambda Sensor Spacer(s) to prevent the engine light coming on in most cases. If you search our other items you will find these.
