Got a question about Header's.. Is a change of Headers from stock to aftermarket beneficial? And how does a change in Headers improve HP?

 

Better flow, less back pressure = more horsepower. Longer the tubes, more HP and the govt. really hates them long tubes, and as such, I never considered shorty's or mid's.
That's basically it, now there's some other high tech **** you can read about having to do with "scavenging" and "vacuum effect" and other technical gibberish showing the advantages of headers, but my first sentence is enough for me, and doesn't give me a headache trying to understand it.

Oh, and they also sound cool as ****!

 

Hammer, you're very knowledgable on this stuff....Let me ask you, I have a single output Flowmaster exhaust. Will i still see a increase in Hp? Also, as far as installation is concerned, approx. how much to install, and can the dealership do the install?

 

yea, should be fine. As a matter of fact, flowmaster mufflers are one of the worst flowing mufflers made (often worse than stock). They give up a lot of flow for great sound (don't feel bad, I have one too). But headers can actually make this work to your advantage. A truck should really have some backpressure so as to not lose much low end torque. It's a balancing game, everything you do to increase horsepower at higher rpm's losses torque at lower rpm's and vice versa. Having a muffler that creates a little backpressure will help here, as well as leaving your cats in. By doing this you also won't have to deal with check engine light on all the time.

As far as the dealer doing the install I can tell you they will charge youout the a_s. They will also probably make you buy Mopar parts (they offer LT Headers, but man they are high). You are probably better off finding a good exhaust shop to do the labor, source the headers yourself and you'll save a ton and probably get a better job than if the dealer would have done it.

 

Damn, this is going to come off as a stupid question, buy hey, i'll ask anyway...Are the "Headers" attached to the exhaust some how?

 

There are no such thing as stupid questions. There are only stupid answers. Or so I've been told. Although I think I've asked my fair share of stupid questions

The headers are the first things your exhaust goes through from your engine, so the answer would be yes.

 

Headers come off each individual cylinder, then attach to the cats, then some sort of "Y", then it's to the muffler then tail pipe or pipes. There can be some variations like "True Duals" or maybe the "Y" after the headers and into one cat then one muffer, but this is the basic setup. The above pic shows the headers, cats and "Y". So the single pipe would connect to your muffler or "cat back exhaust".




This would be the second or rearward part of the system, in this case a muffler going back to a single tail pipe. Of course a single in dual out muffler could be used to culminating in two tail pipes/tips.

And that, would be the entire, very efficient, exhaust system!
