No intrinsic performance gain to be derived, "per se", lake pipes evolved a function of practicality. Common instances, their manifolds routed straight out the front wheel wells posing an asphyxiation risk to the race driver, "lake pipes" were fashioned, extending from the header flange along the rocker panels, bottom-side of the vehicle, beneath the doors, thus allowing (1) suspension tuners a lower ride height sufficient for land speed record attempts, and (2) engine tuners ease and flexibility of interchanging different exhaust manifolds without hoisting the vehicle, thus precluding having to wrench undercarriage of the vehicle.
