Hooker Competition Fenderwell Exit Headers

Hooker Competition Fenderwell Exit Headers bring race-proven exhaust technology to street and strip builds, backed by Hooker's legacy as the winningest header manufacturer in automotive drag racing history. The Competition series is engineered to deliver real, measurable performance gains for enthusiasts running stock or mildly modified engines — combining premium features with exceptional value.

Every header in this lineup is built around a long transition collector design that reduces back pressure and maximizes exhaust scavenging efficiency across the RPM range. Mandrel-bent tubing maintains a consistent inner diameter through every bend, eliminating the flow restrictions associated with crush-bending. The fenderwell exit routing channels exhaust gases out through the fenderwell, improving ground clearance and delivering the aggressive, purposeful look of a dedicated performance build.

Key Features:

• Durable mild steel construction — engineered for long-lasting performance in demanding street and strip applications
• Long transition collector — reduces back pressure and improves exhaust scavenging for power gains across the RPM band
• Mandrel-bent tubing — maintains consistent inner diameter through all bends for unrestricted exhaust flow
• Precision-machined flanges with welded O-ring seals — provides a leak-free sealing surface at every exhaust port, with flange dimensions proven to maintain header integrity while conforming to each port
• Fenderwell exit routing — routes exhaust through the fenderwell for improved ground clearance and a classic high-performance appearance
• Multiple finish options available — standard headers feature a heat-cured, high-heat-resistant painted finish; ceramic-coated variants utilize Hooker's Ceramic Thermal Barrier Coating for enhanced heat management and extended durability

Important Usage Notes:

• Header wraps are not recommended — wrapping can cause header tubes to crack or rust due to excessive heat and moisture retention, and will void the warranty
• Ceramic-coated headers should not be used during engine break-in — use cast iron manifolds or used headers during the break-in period to protect the coating and maintain warranty coverage

Built on decades of professional drag racing success, the Hooker Competition Fenderwell Exit series delivers premium engineering at a competitive price point — making it the ideal performance upgrade for enthusiasts who demand proven results.
