Why this part
Cheap exhaust gaskets compress once and never recover, leaving you chasing leaks between sessions. Aeroflow's steel construction maintains its seal through repeated heat cycles, which matters on a car that sees hard use. At this price point, running anything less on an LS build is a false economy.
