SOUL Competition Headers replace the restrictive factory manifolds on 2005-2008 Porsche 987.1 Cayman and Boxster models with free-flowing T304L stainless steel headers designed to reduce weight and operating temperatures while improving engine response and flat-six sound.

Direct bolt-on installation. Removal of the factory catalytic converters may trigger a check-engine light and is intended for off-road/competition use where applicable. Backed by SOUL Performance Products' Lifetime Warranty.
