Hookers new Super Competition and Competition Headers
for 98–2002 LS F–bodies have all the A.I.R. and EGR Fittings
deleted and are for high output, supercharged or big inch versions of the Gen III (LS–6/LS–7) engine. The Competition versions feature 1–3/4” tuned length 16 gauge primary tubes and a 3” slip fit long transition 9” conventional collector for efficient scavenging and reduced backpressure. The Super Competition and Competition versions both feature thick 3/8” flanges that will seal perfectly and indefinitely and are available in black paint or Hookers ceramic thermal barrier coating.
These high performance Headers
are intended for off–road race use only. These Headers
maintain the high value standards Hooker Headers
are known for. These Headers
are easy to install, offer good ground clearance and come complete with gaskets and hardware kit. Y–pipes are also available to fit these headers.
Full Length Tube Size 1.75", Collector Size 3", Port Shape: Same as Port, ceramic coated
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. Please call Hooker
tech service at 270-781-9741 for additional information regarding ceramic coated exhaust products. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Hooker
does not recommend the use of header wraps as this will void the warranty.
