Apparently, Magnaflow makes a Header style exhaust manifolds with catalytic converters.

Sypnosis:
  • Direct bold on
  • Less weight, about 40-50%
  • Flow is better, gains felt and some dyno'd, more HP for supercharged e46 vs non
  • Can be coated or wrapped
  • One supercharged e46 blew out the cats within months, others report no issue

e9x n52 parts 3 Series

Rear: 49763

EDIT 2: ignore 1series parts below, apparently never in production.
EDIT: 1 series Specific( ignore this)
e82/e88/e87 n52 1 series (no images)
Magnaflow 49750 Front; Magnaflow 49751 Rear


Cost: 700-850 each front and rear(the cheaper manifold)
Cheapest place is truckpartshub.com, but not sure if credible there are mixed reviews


For e46 the 3d images looked accurate to the real deal:
