Custom-engineered, mandatory OE-quality quarter-inch thick dual-layer waffled Inconel heat shielding with internal 3000°F matting surround the Performance Downpipes, providing peace of mind for preventing heat damage to neighboring componentry. Factory-correct fitment and AWE’s unprecedented No CEL Guarantee come standard. Please Note: The AWE Performance Downpipes are for Racing Use Only.
