This set was made for a race car which is why the springs were retained. The tubes move around a bit during the first few heat cycles. Slip joints at the collector allow the tubes to settle out and not be under stress as they can be if welded, leading to premature failure due to cracking. Once the tubes settle and harden the springs can be removed if desired.
