How to Check for Busted Chevrolet Headers
You wanted your Chevy to not only look great but to also perform better. Out of the range of modifications and upgrades that you can do, you decided to hook up your ride with a performance header to get optimum flow efficiency. The header is designed to enhance engine performance. Flow efficiency is achieved by letting the engine push the exhaust gases out of the cylinders more easily. Basically, the manifold's back pressure is eliminated. Instead of having a common manifold, each cylinder is given its own exhaust pipe, which is cut with the same length and bent the same way. This design enables exhaust gases from each cylinder to get to the collector evenly spaced out, eliminating the back pressure. By letting the engine breathe easily, by inhaling and exhaling more efficiently, the mod or upgrade promises power gains and more torque. But as with any exhaust component, there can be issues along the way. To help you diagnose problems related with Chevrolet headers, we've come up with a short list of symptoms and hints for troubleshooting.
Model-specific header problems
Although aftermarket headers are designed to improve engine performance and efficiency, making it easier to generate power and torque, not all can provide the desired benefits if the headers are not properly matched to a specific vehicle model. In some cases, they may even interfere with other auto parts. The problem may arise if the headers don't meet the specs and requirements, even if a complete kit is used. Before getting headers, make sure that these are designed for the specific vehicle model.
Although some headers are designed as bolt-on accessories, installing them may present some difficulties, especially for newbies. If they're not installed properly, not only will they fail to deliver the promised benefits but they can also cause problems with the exhaust. They won't be able to effectively reduce back pressure and push out exhaust gases more easily. You have to be sure that the headers are properly installed. Monitor the performance of the vehicle. If there's any irregularity, check the installation and consult a specialist.
Exhaust noise and leak
Unusual noise often means trouble. So if you notice strange sounds from the exhaust, you must check for leaks. Check the lines and pipes for cracks and openings or any possible source of leak. Don't ignore this. Take a closer look at the vehicle's exhaust system. Test the pipes and search for any sign of damage. See if the headers are properly connected and inspect other attachments and fittings of the exhaust system. To prevent exhaust problems or to fix them before they get worse or cause more serious problems, have your exhaust system checked periodically. Also check your mods and upgrades.
Poor fuel economy and loss or lack of power
If you noticed diminished gas mileage or the engine seems to lack or lose power and torque, you have to check for restrictions in the exhaust. The headers should allow the engine to breathe easily, allowing the efficient flow of gases. However, if the desired benefits are not achieved and the opposite is happening, there could be a problem with the headers. They have to be inspected and tested. The rest of the exhaust system should also be checked to rule out other problems.
Everything a vehicle owner needs for a header, Flowtech will offer. From emission-compatible headers to standard, mid, and full-length headers, there's no vehicle application this brand won't cover. What make Flowtech headers stand out among the competition are their tuned-length primary tubes that are designed for optimum street performance, the mandrel-formed power plenum collector that ensures low back pressure, and leak-tested o-ring port seals, which guarantee a leak-free operation. Made from lightweight yet 16-gauge tubing, these headers won't add weight to the vehicle. They are also easy to install as they are packed with the necessary mounting hardware and premium gaskets. These headers are 49-state legal; they can be shipped to any state except California. In case of defects, there's no need to worry; Flowtech headers are covered with a manufacturer's 90-day warranty.
Pacesetter headers ensure a perfect blend of ease of installation, perfect fit, and maximum performance gain. They boast oxygen sensor fittings across all applications, making O2 sensor installation a breeze. The headers' flash-controlled 16-gauge carbon steel primaries provide them with their much needed durability, so they'll last long even in the harshest of working environments. Pacesetter headers are more durable compared to light gauge stainless steel units. These headers also feature CNC-machined thick steel flanges that fit perfectly to exhaust port profile. With such flanges, optimum exhaust flow and quality seal are guaranteed. They are covered with a 3-year manufacturer's limited warranty, and they can be shipped in all states but California.
For short-style headers, Gibson has the answer. This brand makes use of high-quality 409L stainless steel mandrel-bent tubing to make its headers capable of maintaining steady flow of exhaust for optimum vehicle performance. Made and dyno-tuned to be a direct bolt-on replacement for stock exhaust manifolds, Gibson headers will sure deliver more horsepower and torque. And by simply allowing the engine to breathe easily and to operate at cooler temperatures, these headers make the engine even more efficient. They can be attached to OE crossover pipe without modifications needed, so part compatibility will never be an issue. Gibson headers can be used on both lowered and raised vehicles as well as in street and off-road applications. However, they can't be installed on vehicles employing EGR and air injection system.
