    Hedman Extreme Duty Hedders

    Hedman Extreme Duty Hedders Chances are if you use your Chevy vehicle for the extreme, using the stock manifold you'll want to replace your OEM exhaust manifold with an aftermarket header. The cast iron stock manifold manufactured for your Chevy was not built for the high performance or grind of extreme living. As your engine works, exhaust gases accumulate and are pushed to the stock manifold. Because not every cylinder fires at the same time, timing differences between the various components of the exhaust system means your vehicle has to work hard to evacuate the revolving door of exhaust gases. Old and new exhaust mix and form pressure waves that reduce the airflow through the engine, limiting the vehicle's power and performance. A header designed for the extreme may be price prohibitive, but the savings and increased performance you get make such a sacrifice worthwhile. Replace your Chevy stock manifold with an Extreme Duty Hedder and improve its speed and efficiency. Thicker primary tubes and head flanges make this Hedman Hedder more resistant to burnout and damage from excessive and a good overall investment. Hedman Extreme Duty headers pull exhaust gases out with force than standard manifolds so that your engine cools faster and power improves. With improved power come maximum performance, increased economy and toughness to handle the rough and tumble world of your vehicle.
