These JBA Performance Exhaust shorty headers are equipped with an exception to the California Air Resources Board (CARB) Executive Order (EO). According to the application manual and the manufacturer`s installation instructions, they are legal for 50 states if they are installed on the corresponding vehicle. A straight pipe is just that, a pipe that, unlike standard exhaust systems, is straight and without restrictions. There are several reasons why it is illegal. The first is obvious for noise regulation. The second is emissions, which are more difficult to circumvent in some states because they have to be reviewed annually to pass the inspection and register or insure your vehicle. According to New York`s auto laws, a vehicle must have a proper muffler and exhaust system, which makes straight pipes illegal. I think most of us will agree that a white Chevrolet/GMC pickup truck that drives on the highway is not something to be very happy about. The reality is that these microphones are a dozen. Knowing that a white van was almost invisible, we decided to give a little more sex appeal to our GMC Sierra. We started by adding an emissions ProCharger that increased the truck`s power from 260 horsepower and 281 lb-ft to a healthier power of 419 horsepower and 422 lb-ft of torque.
And while we`re happy with the new gains, we can`t help but think that the factory exhaust system could be an obstacle. So our next step was to find a great sound escapement in hopes of releasing a few more ponies. However, we wanted to update the exhaust to remain legal in California. Since this is a Californian truck, it is prohibited for 91-octane parts and CARB legal parts. While a trip across the country to the east quickly takes us to the 93-octane Promised Land at gas stations, this plan is not practical. The only way to achieve a higher octane in California is to use an octane additive in the tank. Fortunately, VP Racing Fuels manufactures Octanium Unleaded Octane Booster. Update in January 2022: If you are planning to modify your vehicle, you need to make sure that the changes are actually legal for road traffic. That being said, however, there are illegal mods that people get away with most of the time.
What you need to have: Components to improve engine performance, such as the upgrade ECU, turbo units, exhaust manifolds, intake manifolds, and other emissions-related components, can cause problems during smog testing, but if evidence is provided that the upgrade units are legal for use in California (they have an EO number) or OEM parts, they will not fail a vehicle in smog tests in California. Will aftermarket headers cause my car`s smog test to fail? JBA long tube manifolds are the first choice for maximum performance and efficiency at high speeds. These long tube header designs are Dyno and Race, which have been proven to offer the greatest possible increase in power and torque over the entire rev range. With an elevator and the right tools, we installed all JBA components, short manifolds, new wires and rear exhausts in less than five hours. When we turned on the GMC, we were pleasantly surprised that the exhaust was noticeably stronger when starting cold. Overall, the exhaust is more audible at idle and with the throttle wide open. The good news was that the exhaust didn`t skyrocket or make noise at the partial throttle, a common complaint of many aftermarket exhaust systems. We liked what we heard about the JBA configuration.
The next step was to put it to the test and see how much power we had gained. Adding colorful lights to vehicles became very popular after the movie “The Fast And The Furious”. According to Find Law, it is legal in some states to have too few incandescent lights until they are visible or strobe. While state laws vary, according to Extreme Tactical Dynamics, vehicles other than emergency responders are not allowed to have flashing red or blue lights. Some state laws prohibit all colored lights anywhere on a vehicle. When it comes to changing your suspensions, whether you`re lifting or lowering, there`s a limit to the height or drop you can reach. Each state has its own laws that limit both, but most have different laws that restrict height restrictions on bumpers and headlights that would make the extreme cases of both illegal. Under elevator laws, NJ limits the amount you can lift your vehicle based on weight and requires all lifted vehicles to receive a “high vehicle approval certificate.” The state of Georgia allows you to legally elevate your vehicle up to two inches. If the performance enhancement component you want to add or install on your vehicle, whether it is a compressor, turbo unit, air intake, manifolds, etc. is not listed on carb`s website, it is not intended for legal use in California, except for off-road use only in certain circumstances, and it could prevent your vehicle from passing the smog inspection. Tinted windows are a common mod on cars for which a police officer won`t usually bother you, but it`s always a reason to stop you if you`re not doing anything else wrong. Tinted glass is achieved when a darker colored film is glued to your windows, creating dark glass.
Each state has different dyeing laws, some of which are stricter than others. Recently, according to DMV, a New York State vehicle will not pass its annual inspection if its side windows are tinted beyond the legal limit. It is ignited by the hot pipes, which causes flames to erupt from the car`s exhaust. How does the fuel manage to get into the exhaust system? According to Car Throttle, this is usually due to the removal of the catalytic converter and the addition of straight pipes, so you guessed it; illegal.
