Someone know about exhaust performance gain?
Okay, I am probably an idiot, but I am an electronics guy so give me a break haha. What I am wondering is how does a better exhaust increase performance in our trucks? The way I figure it is that all of the major engine functions end after the headers, and the rest is to get the fumes away from the truck no? Someone please enlighten the misinformed...

Header design is the most crucial when it comes to a performance tuned exhaust.
That's not to say that from the collector back isn't important, it still is. But only in the sense of controlling volume and velocity.
LOTS OF VIDS - Money can buy HP, but it takes the driver to make it fast

Exhaust back pressure can influence the torque and speed of the engine. Headers typically allow for better scavenging of the combustion chamber (cylinder) meaning that if all the tubes have the same effective length and equal pressure drop they will actually clean out the combustion chamber by causing a lower pressure in the header. If you are building for speed this is a very good thing. Sometimes you don't want that such as when you are attempting to increase torque more than speed you may actually want to have more back pressure in the exhaust.
Nice truck - You wouldn't mind if we take it away and redistribute it to someone who doesn't have one. Would you?
