ARH / Vorshlag headers with 1.75" diameter full length primaries made with 304 Stainless Steel 3/8" Laser Cut flanges, CNC bent primaries & precision formed collectors. All welding on this set of headers is built on production fixtures for accurate repeatability and the best possible fit. Stainless steel weld-on O2 bungs are included. Due to chassis constraints near the collectors these need to be added just downstream of the header V-band collectors. The included pair of V-band "clamps" are from a U.S. parts supplier (not imported junk) and the V-band flanges are made to Vorshlag specs in the USA, and are also 304 Stainless Steel.
we highly recommend using them in conjunction with our Vorshlag E46 LS1 Motor Mount kit and Vorshlag E46 T56 Transmission Crossmember kits. We also strongly recommend using the Vorshlag low profile E46 Steering Shaft Assembly for additional clearance*
