I know I dont now cars. Can someone break this down into English. Not just Kook Headers but Headers?? Is this a mod for just exhaust noise or does it add performance?? Or Both? And if thier is a simple answer on how this works I would appreciate it. Sorry to be a pain but for those of mechanicaly challanged people, we need help.

Headers move exhaust gases FAST. That allows the engine to cycle fuel and air quicker. This = Increased performance. You have to remember, that the only thing that makes power in a motor is airflow. An engine is nothing but a big airpump. The more air it pumps, the more power it makes. Headers move it faster on the tail end of that cycle.:beer:

You've waited all this time to ask? :lol:

OK,.. Headers add performance and give you a better exhaust sound.

I'm not exactly sure how to explain it though. I'm sure someone who's better with words will chime in soon!

Headers are typically designed so that each exhaust port is the same length so that each exhaust port sees the same back pressure.

This is a great web site that will break it all down for you!

btw- headers/exhaust manifolds are located on either side of the engine. :pimp:

Patrick, best way to break this and any other questions you have is GO TO ATLANTA BREAKFAST CLUB!!! The place is crawling with fine Southern gentlemen (and a lady or two) who would be glad to help you out. It's only a few hours from you, and the folks there are awesome. Another idea is go to the library or online and look up anything about performance parts and engines. BTW, headers are on the sides of an engine, below the heads. Take care my good man.

Thanks Paul. But I seem to be on Todds short list. He knows the schedule I work. Maybe one day have a 9-5 job. But working so many hrs and looking out for Mom @ Dad. Opps venting sorry. Thanks for your help. I hope to make to Atanta sum time!

Maybe I could stop by and visit sometime. I can show you lots of the mods on my car. I drive back and forth from Knoxville to Atlanta frequently, usually in the company van instead of the MM but I will be driving back from ATL tomorrow and then back to ATL Sunday evening or Monday morning.

Headers are typically designed so that each exhaust port is the same length so that each exhaust port sees the same back pressure.
And when the primary tubes (the ones coming directly from the exhaust ports) join together at the "collector", through the miracle of engineering & higher mathematics, each exhaust "pulse" going through the collector creates a slight negative pressure or "draft" on the remaining primary tubes. This negative pressure allows gas from the next cylinder opening it's exhaust valve to move through it's primary tube that much easier/faster and when it hits the collector it creates a draft for the next cylinder and so on. This is commonly refered to as exhaust scavenging.
I hope that makes a little sense (it was the best I could do w/out boring you to sleep)!

The thing to keep in mind about headers is that they take the point at which each of the primary tubes join together into one pipe further away from the engine than the stock exhaust manifolds do, which gives the hot expanded exhaust gases that are coming out of the cylinder heads a little more time to cool off and contract before they have to be squeezed into the collector tube (which is where the four primary tubes meet into one pipe).


So that in itself reduces exhaust back pressure, and speeds up the rate of the exhaust flow. And in addition to that, the primary tubes of the headers have a larger diameter than the exhaust manifolds that they replace. All this leads to increased engine power since the excessive back pressure of the stock exhaust manifolds have to be overcome by the power of the engine being produced by each power stroke of the pistons, and it takes a certain degree of power from the powerstroke of the pistons to push out the exhaust gases of the other cylinders that happen to be on the exhaust stroke at the same time.

It's like if you take a common manually operated bicycle pump, and push the pump handle while the air valve isn't hooked to anything. It's very easy to operate since there's no resistence. Now do the same thing while squeezing your thumb very tightly over the air vavle. You'll notice that it's a bit more difficult to push down on the pump handle due to the increased resistence that's created because of the back pressure of the air that has to pas around your thumb. Well that increased resistence is just like the increased back pressure that's created by a facory stock exhaust system which includes the exhaust manifolds. They simply create more resistence for the power stroke of each cylinder in the engine, and therefore that robs power from the engine and reduces the rate of acceleration just as adding 1,000 LBS to the weight of your car would cause more resistence to the power stroke of each cylinder and would also decrease the rate of acceleration.

Great explanation Billy! :up: I had a basic understanding of how headers work, now I know a bit more!

CRUZTAKER

Well....even I learned something.:up:

All I can to your insight FIVE-O is that it was the complete KOOKS system that helped me achieve over 300 hp at the rear, plus a dozen compliments a day regarding the sound.

Best performance add I have done thus far...and the most expensive as well.

Barry makes an interesting observation here. because the bottom line is, HP costs money. And the faster you want your car to accelerate, the more it's usually going to cost you. For instance, the Kooks headers and complete exhaust package cost me $1,600, and it shaved .55 seconds off my 1/4 mile ET's. While the Trilogy S/Cer kit cost me $6,000 and shaved 1.6 seconds off my ET's. How fast do you want to go? It's as simple as that. BTW, I'd highly recommend both Mods. :up: And I agree w/the statement about how great the Marauder sounds w/the complete Kooks header & exhaust system. I too am constantly getting people driving up to me at a red traffic light and saying things like "Wow your car sounds great. What do you have under the hood of that thing?"......

Look, there are so many things you can do with this car, you have to set a priority list, unless you are Marty, who can spend whatever he wants when he wants to, and then just stick to the plan as the budget permits. If you do the engine first (Stage 1) with the headers, you'll see immediate results, and then move toward the rear as the pocketbook will permit. If you can do it all at once, go for it. You won't regret any of it!:banana:

Patrick,
Sorry I didn't get back to you this weekend. One of those pesky work things came up. Gotta pay the bills (and Marauder upgrades) somehow though.

Seems like there is a backlog on the Kooks headers, so you'll have to wait awhile even if you order them now. I would recommend a chip. Probably either a SCT tuner or a SCT chip would be your best bet. You have to decide whether a generic program that you can have tweaked by phone and mail (occasional dyno tunes but you gotta drive for it) suits you better or if you want to be able to have your program readily adjusted after you make more mods. A chip will help the mushy tranny shifting. Next, I think the 4.10s are a great help. That will help the takeoffs. With those two mods, I was happy with mine for a few months. Then I wanted more. So the headers came along, and then the underdrive pulleys. But one thing to be aware of with the chip and/or gear change is that some cars (not all of them) develop a driveshaft vibration with the higher rotating speed, so you may have to throw in a driveshaft.

Yes, Patrick.........YES! Wonderful place to start. If you plan on driving over 120 mph on a regular basis, you WILL need an MMX driveshaft. Otherwise, it can wait until you upgrade your differential and rear ring and pinion set(that's how I did it, and it worked great).:banana:

Thanks Jim!!! I am going with my first thought on mods! Stage 1 from Dennis. 4:10s ( My dealership can have it dun for under $500) Then Kooks! FordNut says thier is back order on them. And for almost $1900 and need to find a place to get them dun. Dealership not up for this! Team Ford is my best option. Oh I have had her at 105 mph so I dont plan on 120MPH. But after Mods?? Who knows!!!!

No problem!!! But about the chip. SCT tuner? I dont need tech help with this. That stuff is probably beyond me. Just some insight and what would advise?
The SCT tuner allows you to reload your cars computer with a high performance program. It does this through the diagnostic port. You can return to the stock program or change to a different program. You should return to stock program before going to a dealer who may update to a newer version Ford program. You can run on one program, to change programs requires reloading.

The Chip, and I would recommend a new Superchips chip instead of the older Diablo chip, requires the computer to be taken out of the car, a knock-off cover removed, and a connector to be cleaned off from the computer. Then the chip is plugged into this connector. The chip can be ordered with multiple programs, suppose you want a performance program which requires 93 octane and a milder program which is setup for 91 octane or maybe a performance mode and a valet mode which limits the car to 35mph. You can switch between the programs by flipping a hidden switch which comes with the chip. You can even setup the chip so that the switch has an "off" position for when you go to the dealer.

My preference is the chip but that is all a matter of opinion.

If you're really hardcore (I know I am), then you can get the SCT racer package from Modular Depot, which will allow you to program your chip or the SCT handheld tuner, and tune it however it suits you. Check it out at www.modulardepot.com (http://www.modulardepot.com). :beer:
