2020-01-20 - BMW E46 exhaust manifold

What is the point value charged to run the BMW E46 vehicle with OEM BMW E36 exhaust manifolds (as required in spec E46 class)?

As the catalytic converters are built into the e46 exhaust manifold, a swap of the E36 exhaust manifold would incur zero points.

The approved factory E36 BMW exhaust manifolds that ChampCar will allow on an E46 for zero points are:

  • part # 11 62 1 744 250
  • part # 11 62 1 744 251
