Know Your Code
JBA understands the importance of blending performance with today's mandatory emissions regulations. Beginning with the development of the very first CAT4Ward design over 30 years ago JBA Performance Exhaust has worked closely with the California Air Resources Board (C.A.R.B.). We continue to product and bring to market more 50 state emissions legal header applications than any other manufacturer. We have watch emissions laws and standards grow beyond California's borders into as many as 15 other states. The adoption of California emissions requirements by other states will most likely continue for years to come. We recognize this and are committed to bringing performance to our customers within these guidelines. Not only do we work closely with C.A.R.B. to gain Executive Order (EO) numbers for new applications, we work diligently to update and re-test applications as needed to ensure our EO's are the most current in the industry. Most JBA CAT4Ward Headers ship with a certified emissions decal which displays the appropriate C.A.R.B. E.O. number for easy identification. Refer to the codes throughout this site to confirm your header application is covered by one of our Executive Order numbers. Combined with our reputation for quality and engineering, you can rest assured that you get the most performance for your money while keeping your vehicle emissions legal.
