Kooks Headers Catted X-Pipe Exhaust System

The Kooks Headers Catted X-Pipe Exhaust System is a high-flow exhaust crossover solution engineered to bridge the gap between Kooks long tube headers and your vehicle's rear exhaust section. Using proven X-pipe scavenging technology, exhaust pulses from opposing cylinder banks merge and equalize pressure across the system — extracting measurable gains in horsepower and torque while delivering a deeper, more aggressive exhaust note without excessive drone.

Built to the same exacting standards as the headers they're designed to accompany, every Kooks Catted X-Pipe is handcrafted at the company's Statesville, North Carolina facility and backed by a limited lifetime warranty to the original purchaser.

Key Features:

• X-pipe crossover design harnesses exhaust scavenging to reduce backpressure and maximize flow from both cylinder banks
• High-flow catalytic converters maintain street and highway emissions compliance without sacrificing performance
• GREEN Cat high-output options available across select applications — EPA-verified high-flow catalytic converters engineered for modern muscle cars and forced induction platforms
• T304 aircraft-quality stainless steel construction resists corrosion and withstands repeated high-heat cycles
• Mandrel-bent tubing maintains a consistent inner diameter throughout for unrestricted exhaust flow
• Precision TIG-welded joints ensure long-term durability and a leak-free connection
• Direct-fit engineering designed to connect seamlessly to Kooks long tube headers and OEM-style rear exhaust sections
• Dyno and race tested to verify real-world power gains before reaching customers
• Made in the USA — handcrafted at Kooks' own facility, independently owned and operated
