The prompt
Create a smooth 2-to-1 exhaust collector. Two inlet tubes, each 50.8 mm outside diameter The two inlet tubes are parallel The center-to-center distance between the two inlet tubes is exactly 55.8 mm This gives exactly 5.0 mm clear gap between the outside surfaces Both inlet tubes enter the collector straight and parallel Merge both inlet tubes gradually and symmetrically into one single 50.8 mm outside diameter outlet The outlet must be centered exactly between the two inlet tubes Total transition/collector length: 100 mm Wall thickness: 1.5 mm Create a smooth Y-shaped transition over the full 100 mm length Fully open internal flow path No internal divider at the outlet No overlapping walls No intersecting cylinders Do not simply boolean-union three tubes Create a true smooth collector transition between the two parallel inlets and the single outlet Keep the outer surface smooth and continuous Keep the internal transition smooth without sharp steps Final model must be one watertight solid body Suitable for 3D printing and later fabrication as a stainless steel exhaust collector Export as STEP Important: preserve the 55.8 mm center-to-center spacing at the inlet end and gradually reduce this to a single centered 50.8 mm outlet over the 100 mm transition length.
