JBA Performance Exhaust uses a voluntary product identification program whereby all emission sensitive products can be identified by placing numbered labels in product packaging and listing corresponding numeric codes next to each part number. The corresponding numbers and explanations are as follows:

This product is Legal for use on 1974 and older non catalyst equipped vehicles and is considered a Replacement Part per California Air Resources Board regulations, as long as ALL emissions sensitive components are retained, including A.I.R., EGR, Heat Risers etc. Failure to retain any of these components, or use on any 1975 or newer catalytic converter equipped car would render this product Illegal for Street or Off Highway use in California, or in states that have adopted California Emissions regulations and may only be used for Closed Course Competition.

This product is Not legal for Street or Off Highway use in California or in states that have adopted California Emissions Regulations and is only intended for Closed Course Competition use, except 1965 and older US manufactured California Certified vehicles, 1967 or older US manufactured Federally Certified vehicles, or 1967 and older Foreign manufactured vehicles which may have any aftermarket add-on or modified part installed as long as the vehicle can still meet the tailpipe emissions standards for the year of the vehicle and retain any original or retrofit crankcase control (PCV) devices and NOx device required for the year of the vehicle.

JBA shorty headers are one of the best performance upgrades available for any application. Hot Rod 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. 1. Mandrel-bent stainless steel primary tubes- Best flow, durability, improved throttle response 2. Proprietary JBA Firecone collector- Race proven technology for maximum hp/tq gains 3. Factory style emission connections- Easier installation 4. Extra thick collector domes- Will not distort like lesser quality headers, no leaks 5. JBA Badge-Authentic JBA Quality 6. 3/8" thick machined flanges- Resists warping, prevents leaks, & easier install 7. Oversized exhaust ports- Increased flow, accommodates cylinder head porting 8. Available with two optional coatings polished metallic ceramic, titanium ceramic-increased corrosion protection, thermal barrier for lower underhood temperatures
