The Active Autowerke Downpipe Exhaust Upgrade is designed specifically for the BMW S58 engine found in the F97/F98 X3M and X4M models. It addresses the restrictive nature of the OEM downpipes to improve exhaust gas evacuation and turbocharger responsiveness.

  • 3 inch diameter stainless steel piping for improved flow and durability
  • Incorporates stainless flex joints transitioning to 70mm diameter to match the OEM exhaust system, never dropping below stock diameter
  • TIG welded 304 stainless steel construction with 1.5mm wall thickness for strength and longevity
  • Precision fitment ensures a direct bolt-on installation with no cutting or welding required
  • Designed to reduce turbo back pressure for quicker spool and enhanced power delivery
  • Manufactured in Miami, Florida

This downpipe system is engineered to optimize turbocharger efficiency by minimizing exhaust back pressure without sacrificing daily drivability. Intended for off-road and racing use, installation will result in a check engine light unless combined with an appropriate software upgrade from Active Autowerke.

Fitment: BMW S58 engine applications in F97/F98 X3M and X4M.

Note: This product modifies the factory emissions system and is intended for off-road and racing applications only.

Very cool and comfortable pillows. Great value.
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
These pillows are everything described on the site. They do retain shape and don’t flatten out after sleeping all night. They are nice and clean looking and comfortable. The fit on my king size bed is perfect cause I prefer the size to king size. Haven’t had to wash them yet but I have had other pillows with the same material inside and the wash ability is great.

Great pillow
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
The pillows feel great. Being able to remove portions of the interior allowed me and my wife to have a perfect fit. They do stay cool which seems to have helped with my restlessness.
