99-01 GM Truck 4.8L & 5.3L
magazine rated headers as one of the top 10 power parts installed on a vehicle. JBA shorty headers are
significantly less restrictive than the stock manifolds on a vehicle and dramatically increase the power and
efficiency of an engine. JBA's original shorty design is an innovation of the old long tube header. The new
shorty designs yield high performance gains that hot rodders and enthusiasts look for. With durable stainless
steel construction that can survive the abuse of racing, towing, and daily driving, these headers can take a
beating. With heavy duty features and proprietary technology, like the JBA Firecone collector JBA shorty
headers have the capacity to produce more power than any other shorty headers on the market. Each
system includes high quality hardware and thorough instructions for a professional no-leak installation.
