I dive a 92 chevy and i just recently bought headers and dual flowmaster super 40's. They aren't going on till friday but i was wondering what kind of headers i should expect. At the moment it has a stock manifold and pipes with a cherry bomb. I can imagine there will be a great difference in sound I can imagine there will be a great difference in sound but what kind of performance headers hp gains am i looking at? You're prolly thinking the truck is fairly old and wore but over the last few years I've basically overhauled the entire truck. It has a 5. I'm not looking headers race but are there any other suggestions for increased performance? I don't have a ton of money. Are you sure you want to delete this answer?

Your engine is basically an air pump, air flows in and air flows out. Anything you do to improve either of these things will improve performance. Dual exhaust is another way of increasing this, uses a catalytic converter which is restrictive as well. Try looking into a high flow cat too. The flowmaster 40 series mufflers are a great set up for both headers and sound quality. You aftermarket not feel a kick in the pants with only headers and mufflers, but there will be some increase in bot HP and top end speed because the engine will breathe a lot easier. You didnt give a lot of info about the engine, so you may want to swap out to an aluminum performance manifold, headers a bigger camshaft, camshafts are the heart and sould of improving performanceare you running carb stock fuel headers You can still do a performance chip upgrade and cold air intake too. Headers are a lot of possibilities that you headers looking at. The difference between headers and the stock manifold is how they are made. Stock manifolds car makers put on there vehicles are stock made for performance and normally add a lot of back pressure. Headers are made to let the exhaust flow with out being restricted. Trust me there is a big performance difference though they may look alike. Remember that fuel and air can only enter the motor as fast as the exhaust leaves. Without some aftermarket modifications, headers make a slight improvement over a normal stock exhaust with free flowing mufflers. However, headers can scavenge exhaust headers more efficiently so a slight improvement in fuel economy is possible. The biggest change and up to 20 to 30 horsepower increase is simply going to true dual exhaust. Headers can provide a couple more but nothing drastic for a stock engine. Changing the camshaft is really the biggest cheap improvement. For a small block Chevy headers lift around. Much more noticeable than headers, but harder to install. The price of cams and lifters isn't much more expensive than exhaust work. But it is harder to install because it's inside the engine. Modern fuel injection would be able to handle a modest cam and exhaust without much aftermarket. I have owned several Money Pits myself. Chery bombs are basically worthless. Kids buy headers thinking headers have something because they are load. Stock of like those buzzo exhaust for small cars. I hate those thing. Looking for car insurance?
