JBA Speed Shop and Livernois Motorsports have a long standing partnership which spans more than 20 years. JBA is proud to announce that we are now offering a 50-state smog-legal high-performance tune for your late-model car, truck and SUV. Look for your vehicle in the list below!
Emissions testing in California has evolved over the years from sniff-tests, to on-board monitor completion and now checking for OEM calibrations or aftermarket tuning that has emissions legal status. JBA has a long and successful history providing maximum performance while maintaining 50-state compliance, including developing the original CARB-Legal JBA Shorty Header. These emissions-legal tunes carry on that long tradition.
