Description
Performance. With better exhaust flow, the Kooks 1-7/8-Inch Long Tube Headers help make the engine work better. The improved ability to remove waste gases helps to remove them from the engine more effectively, which improves the burning process and power output, especially at higher engine speeds.
Reliable. The Kooks 1-7/8-Inch Long Tube Headers have bigger primary tubes than the stock exhaust manifolds. This helps the exhaust gas to flow better. This benefit helps to decrease resistance and make the engine work better, which leads to more power and strength.
Power. The Kooks 1-7/8-Inch Long Tube Headers make the vehicle sound louder and deeper than the normal exhaust system. This benefit is attractive to people who enjoy high-performance and want a more exciting and fulfilling sound from their Sierra 1500.
High-Quality. The Kooks brand has long tube headers that include a high-flow catalytic converter Y-pipe. This Y-pipe has special catalytic converters that let the exhaust flow through better, while still following the rules for keeping emissions low. Kooks headers are tested on a machine to make sure they improve performance.
Control. Using Kooks 1-7/8-Inch Long Tube Headers can make the throttle respond better because they help the exhaust flow more easily and reduce pressure. This perk makes the Sierra 1500 feel more quick and nimble, improving the overall driving experience.
Efficient. While it may not be the main benefit, a few Sierra 1500 owners might notice a small increase in how far they can drive with the fuel they have if they install Kooks 1-7/8-Inch Long Tube Headers. The better burning of fuel and less strain on the engine can slightly improve fuel efficiency, especially when driving on the highway.
Installation. Putting this Kooks 1-7/8-Inch Long Tube Headers with High Flow Catted Y-Pipe on your 5.3L Sierra 1500 is easy and requires no drilling.
Warranty There is a limited lifetime warranty on this product.
