The Active Autowerke Header Set for the BMW E46 M3 is engineered to optimize exhaust flow by eliminating common restrictions, improving overall performance without power loss. With precisely matched equal length runners designed to enhance exhaust scavenging, these headers provide consistent flow tailored for both naturally aspirated and supercharged applications.

  • Constructed from durable 100% 304 stainless steel
  • Designed with robust exhaust flanges and recessed mounting holes for straightforward installation
  • Complete hardware kit included: BMW factory gaskets and copper locking nuts for a secure fit
  • Test-fitted on a BMW S54 jig for accurate fitment and verified oxygen sensor placement
  • Available in polished or brushed finishes to suit your aesthetic preference
  • OEM-style fitment ensures bolt-on installation for street and track use
  • Two-year warranty included

Note that installation requires temporary removal of the four oxygen sensors; Active Autowerke provides a schematic diagram for correct sensor placement to avoid engine alert issues. This header set is designed for off-road applications, as factory catalytic converters are removed during installation.

DO NOT PURCHASE THIS BOOK.
Format: Paperback, Format: Paperback
If I could give zero stars, I would. Do not purchase if you intend to use the Access Code. I was very careful to scratch off the Access code, but you can see it was still unreadable. I went to the website and submitted a ticket. One option for a reason to submit a ticket is 'unreadable access code", so they know this is a problem. They ask for a photo of the code and a receipt of purchase. I sent both. Then they asked for proof that the book was purchased NEW. This was not noted on the Amazon invoice. I was instructed to reach out to the vendor for the additional info. Or I could spend more money on another access code. There are other study options available.
