Billy Boat Exhaust Headers w/ Heat Porsche 993 Carrera (1997-1998)

Upgrade the exhaust flow of your air-cooled Porsche 993 Carrera while retaining functional cabin heat with the Billy Boat Exhaust Headers with Heat Exchangers. Designed as a direct replacement for the factory header assemblies, these headers combine freer-flowing exhaust routing with integrated heat exchangers, allowing you to improve the exhaust system without sacrificing the factory heating functionality that is essential on a street-driven 993. Each system is mandrel bent from high-grade T304 stainless steel and hand-built with an emphasis on durability, fitment, and long-term corrosion resistance. The headers connect directly to the cylinder heads and factory catalytic converters while retaining the factory heater connections. For 993 owners looking to replace aging factory heat exchangers or build a higher-quality performance exhaust system, the Billy Boat headers provide a stainless-steel solution specifically engineered for the platform.
