A consequence of the problematic nature in adaptation of large diameter exhaust tubing to the undercarriage of ladder-frame or body-on-frame chassis architecture vehicles with altered geometry suspensions, lake pipes evolved to become a front-engined vehicle exhaust archetype crafted by specialty motor sport engine specialists of the 1930s, 1940s, and 1950s, whose preoccupation was optimization of the acoustic effect associated with high output internal combustion engines. The name is derived from their use on the vast, empty dry lake beds northeast of Los Angeles County, where engine specialists of yore custom crafted, interchanged and evaluated one-piece header manifolds of various mil thicknesses, a function of temperature, humidity, elevation and climate they anticipated.
