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. Undoubtedly, the short headers slipped into place much more easily than a long pipe head setup would have done. We decided to test our results on the test bench with a VP Racing Octanium fuel additive in the tank, new PerTronix spark plug wires and a new homolo exhaust for the JBA Performance Exhaust CARB. Good news: the PS were on the rise! We removed the intake manifold and plug-in wires to create additional installation space on the driver`s side. We were a little impatient when we ripped off the plug wires, and after 60,000 miles, the old OEM plug-in wires in our hands collapsed. No problem. We ordered a set of new PerTronix plugwires and hit these babies once both headers were fully installed. For even greater performance gains, discover the ultimate power system with Gibson headers.

Each Gibson exhaust manifold is set to the test bench and is designed to provide more power and torque that can be used at low and mid-rev highway speeds. Improves engine breathability and cools engine operating temperature. Our exhaust manifolds are designed to directly replace the factory manifolds with the standard crossover tube. 50 State Emissions Legal, while retaining all storage emission equipment. These Gibson Performance headers are designed for lowered and raised vehicles as well as on- and off-road use. Meets EPA and CARB requirements. Lifetime Limited Warranty As always, we want to make sure there are no problems with the products we sell. To date, we perform exactly these headers on our SS. JBA Performance Exhaust has an interesting feature hidden in its short headers, a speed spike. This tip, located in the manifold, helps to increase the purification of the exhaust gases. Navigating through the desire to modify a vehicle while adhering to the requirements of smog law can be a delicate balancing act, especially in California.

However, it is possible. In search of a good exhaust system to improve our Sierra, we took care to find a system that had a 50-state exemption from the California Air Resources Board (CARB). This exception would ensure that our truck would pass the smog after we have improved its performance. After all, at JBA Performance Exhaust, we found exactly what we were looking for. JBA had both a set of shorty headers with a CARB exception and an exhaust system that would give us the sound and performance we were looking for. JBA Performance Exhaust (PN 1850S-4) short headers screwed without much drama, which says a lot about installing the header. Shorty headers are legal because they do not affect the position or use of factory catalysts. The headers are JBA with a high temperature coating. Once the JBA short circuit strips were tightly tightened and our new PerTronix/JBA connector wires were firm, we moved to the back of the exhaust. As the standard exhaust was simply too quiet for our taste, we opted for JBA`s Performance exhaust system (PN 40-3051), which would replace the exhaust south of the catalytic converter.

Again, the key is to leave the storage catalyst alone and in the storage location to achieve CARB compliance. 4. Extra Thick Collector Domes – Won`t deform like lower collectors, no leaks Cat4Ward® Shorty JBA manifolds are designed to accommodate all emission control devices while providing increased performance, especially in the mid-power range where trams will notice the greatest improvement. Cat4Ward® JBA headers screw to the engine in front of the catalytic converter and maintain the bearing position, thus complying with emission regulations. JBA is working with the California Air Resources Board (C.A.R.B.) to obtain executive orders (EO numbers) that certify Cat4Ward® Shorty headers as issuance in all 50 states. These products have been approved and are marked with an emission code 1 on our product pages. Cat4Ward© JBA headers are ideal for your daily driver or trusty van that you use for transportation and towing. The JBA Shorty headers are one of the most powerful CARB LEGAL (CARB EO #D-57-33) upgrades for the 2014-2017 Chevrolet SS sedan. At Beefcake Racing, we have one of the largest lists of performance parts that comply with the C.A.R.B.

standard. Buy all compressors, cold air intakes, exhaust modifications, tuning and more. If you live in a state that only needs CARB-compliant parts, we`ve got you covered.

Shorty JBA manifolds are significantly less restrictive than standard vehicle manifolds and significantly increase the performance and efficiency of an engine. JBA`s original Shorty design is an innovation of the old long tubular collector. JBA understands the importance of combining performance with current mandatory emissions regulations. JBA works closely with C.A.R.B. to obtain e.O. numbers for new vehicles to offer the latest range of emission head products in the industry. We are committed to our customers and the environment. In addition to the differences, the JBA Shorty and Long Tube manifolds are equipped with JBA`s patented Firecone manifold, which eases the transition between volume changes in the manifold and maintains the maximum exhaust gas speed, resulting in a noticeable increase in performance and efficiency that you won`t find with other headers. 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. On the driver`s side, it wasn`t that easy. We had to unscrew the steering shaft for easy access. It was clear that the installation on the driver`s side would take a little longer than the header on the passenger side. And since our GMC Sierra already had a compressor mounted on the driver`s side, access was a bit narrow, but didn`t make it impossible. Don Lindfors, Director of Exhaust Gas R&D at PerTronix, Inc., said, “It doesn`t surprise me that your installation was easy.

We design JBA headers and manufacture them with the right tolerances so that they fit perfectly. 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. We started our adventure in the store with the JBA Shorty headers. The passenger side was simple. We unscrewed the standard exhaust manifold from the exhaust pipe Y (three screws on the flange) and then unscrewed the head manifold.

The JBA part came in like butter, and we used their graphite seals to prevent annoying exhaust leaks. After closing a few screws, we ended up on the right side of the truck. 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. The new Shorty models offer high-performance improvements that the Chevrolet SS Sedan and enthusiasts are looking for. With a durable stainless steel construction that can survive the abuse of running, towing, and everyday driving, these headers can take a hit. With high-performance features and proprietary technology, such as the Firecone JBA collector, Shorty JBA headers have the ability to generate more power than any other Shorty header on the market. The first step in creating an efficient and powerful exhaust system is the addition of a set of high-end manifolds. The robust and high-quality stainless steel construction, which significantly improves performance, is synonymous with the JBA design philosophy. We offer a variety of SMOG Legal CAT4Ward Shorty headers and long racing tubes for most car, truck and SUV applications.
