Review HEDMAN HEDDERS Hd Silver Long tube Headers 67-91 Gm Truck suv fits SUV

The Hedman Hedders 69820 Long-Tube Headers are a high-performance upgrade for 1967 to 1991 General Motors trucks and SUVs equipped with the 396-502 ci engines. These long-tube headers are meticulously designed and engineered to deliver improved power and performance, making them an excellent choice for enthusiasts seeking to maximize the potential of their engines.

The headers feature 1 5/8-inch primaries, which taper to a sizeable 2 1/2-inch collectors that merge into a single 3-inch exhaust pipe. The larger collector diameter diminishes turbulence and backpressure, which leads to improved engine breathing and efficiency. At the same time, the long-tube design shortens the length between the exhaust ports and the collector, decreasing exhaust gas velocity and scavenging effects for enhanced power output.

Built using premium 321 stainless steel, these headers are renowned for their durability and resistance to corrosion. Each header is hydro-jetted, polished to a mirror finish, and comes equipped withgasketless collector flanges and new Electromotive vacuum secondaries for a perfect seal, ensuring a leak-free installation. The design incorporates conventional bolt-on mounting to make the installation process straightforward and stress-free for DIY enthusiasts.

Additionally, the Hedman Hedders 69820 Long-Tube Headers contribute to a better driving experience by reducing engine heat under the vehicle, as the exhaust gases are directed away from sensitive components. These headers are an ideal upgrade for those who demand better power, improved fuel efficiency, increased horsepower, and a more responsive engine. Supplied with a high-quality gasket kit and new oxygen sensor bungs, these headers come ready for installation, making it a worthwhile investment for any serious GM truck or SUV enthusiast.
