These B&B Exhaust high-flow cat pipes for the Porsche 997 replace the restrictive factory catalytic converter pipes with performance units that maintain emissions equipment while significantly reducing exhaust restriction. High-flow cats are a key middle link in a complete 997 exhaust build, letting headers and rear mufflers work together as a genuinely free-breathing system.
The pipes are mandrel bent from the highest-grade T-304 stainless steel, preserving full internal diameter through every bend for smooth gas flow and excellent resistance to heat and corrosion. Like everything from Billy Boat Performance Exhaust — the American manufacturer founded by race driver Billy Boat — they are designed, tested, and built with hand-made integrity in the USA, drawing on the company's deep motorsports roots.
The set is covered by a Limited Lifetime Warranty. Add part number FPOR-0806 to complete the exhaust path on your 997.
