1.75 in. Long Tube Headers, Black

Hooker super competition headers are with tuned primary tubes to create optimum pressure between the intake and exhaust systems. Breaking in an engine with ceramic coated headers will result in damage to the coating and will void all warranties. Ceramic coated headers require several heat cycles to fully cure before they will withstand extreme heat. Hooker recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating damage. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Features Designed for optimal performance. 5/16 machined flanges for a perfect seal. Long transition collector for decreased back pressure. Light weight & sturdy 18 gauge tubing. Mandrel-bent tubing for smooth exhaust flow. Tuned-length primary tubes for maximum exhaust scavenging and velocity. All necessary hardware included for a complete installation.
