***The factory F430 Exhaust Mounting Bracket has a critical design flaw. The solid mounting to the vehicle’s chassis does not allow for any heat expansion. The lack of expansion causes stress to be pushed back towards the engine and results in cracked headers or catalytic converters. Capristo offers an upgraded mounting bracket that is crucial preventive maintenance item . The Capristo Design utilizes four spring mounted hanging points to allow for this heat expansion (up to 1.5inches). If your exhaust components have already failed DO NOT replace them without also replacing the mounting bracket with the Capristo Design as the will fail again. Both Capristo F430 Exhaust Systems (Valved and Freeflow) Include this mounting bracket.***
