Do you run headers ?

Groucho, I was with you on your previous posts in other threads but don't follow the points made above.

I do agree that some headers can bring noise into the car. I love the sound a of a healthy camshaft ringing the header tubes at idle.

The LS5 in question is still mild. Its got probably a little bit more than it did from the factory. But still running a Q-jet and cast intake. My fairly healthy comment meant that its not a tired old motor...
Well I am looking for a more aggressive musclecar sound. So you are saying I will have a more agressive sound in general by leaving it as is with manifolds?

[/ QUOTE ]Well, I don't know what your opinion of aggressive is. But, as I said, some sound will dissipate through the header tubes themselves. That is a sound I happen to like, but it comes more from the engine compartment area than the exhaust tips. Because of the dissipation of sound from the header tubes,less sound makes it to the tips, usually making it a bit quieter, BUT IMO better in quality. Make sense? In my 1st response, I wasn't trying to talk you out of installing headers. I was just giving you something to think about, so you didn't expect too much

I disagree that headers don't move more air. They do. Sure, eventually the same amount of air can be moved through a Mcdonalds straw, but headers will move more air that those LS5 exhaust manifolds will, given a specific window of time- say a 1/4 mile pass.

I disagree that the sound out of the back of the car will be quieter with headers. I get you theory that sound is dissapating through the headers so there won't be as much sound to make it out of the exhaust tip. I just disagree. There are several other facotrs at work here. I would think they the rougher surface of the cast iron manifold would deaden the sound more that what audibly leaks through a header, but that is just one unaddressed point.

Don't get me wrong, I am fine agreeing to disagree but you asked for some specific points.
