You can be sure it wasn't put there intentionally. It was probably condensation of some sort.

yeah, right now im not the happiest about my car. the check engine light has been coming on and its been idling bad when it comes on..but that is offtopic and i think that should be for another topic. yeah i suppose it could be condensation, would have to be. or watery gas heh

I got it right. Read it again.

Then read this page, and in particular this post.


Same mentality.


Considering your record of BS posts, why should we believe this one?


Assuming you actually made this comparison, the "placebo" effect would explain it.

Norm

Depends on the design goals, budget limits, and space constraints.

Generally mufflers are most efficient, when positioned at the farthest point from the combustion chamber.


They (along with induction systems, ignition timing, etc) increase/decrease cylinder pressure and, in turn, exhaust pressures.

Tweeters and woofers = little, if anything, to do with velocity and everything to do with pressure. Not the best analogy, but it might work.


2 stroke cycle? Cam timing?


4 stroke cycle? Cam timing?


There is. Part of it will be in your "Header" thread.


In school, there were instructors that explained things I already knew, using a language I did not understand. If I had been able to learn that language, I could have used it to write books on the subject.

Until I do, just keep asking for clarification.

Norm

Tune the sound? That is funny.

They were originally designed, and sold, as a "performance" muffler. Nothing but an "echo chamber" with a couple of restrictions placed inside. they induced "turbulence" which deadened sound, but inhibited flow.

The "distinctive" sound is a byproduct of the echo chamber.

Norm

Not likely. The only way to get a clarification from a BS artist, is to show him the picture.


And see if he "gets" it.

Norm

If this is the first time, its probably related to your missing muffler, cat, and tailpipe.

If you use a Scan tool or "paper clip" to retrieve the stored code(s) you should find a Code 13 or 44.

13 = Open oxygen sensor circuit: Make sure it's in place, and hooked up properly.
44 = Lean Exhaust: Computer/carb/dist probably cannot compensate for the missing exhaust system.

Norm

This thread should have been over a page and a half ago..

Just think. If you owned the site (or even this thread) you could do something about it.

But you do not, and you cannot.

Norm

and this thread is more then just my car, in general what makes a car loud for the exhaust. yes i found that taking the cat off makes it louder but maybe in the future i might want to do something else, well legal..so when i put some kind of part on i know it will make it louder just not a waste of money.

So does that mean that a resonator is best used in front of the muffler?



I believe that analogy did work. The more fuel you have, and the more pressure you ignite it at, the bigger "bang" you get?

So to follow that analogy, the more sound amplitude you give a speaker, the harder it will fire, until you reach the threshold where it breaks.

That makes perfect sense to me. Am I missing anything?



Yes, two stroke- No cam, just ports.



Yep, 4 stroke, cam timing, while I don't know any specific numbers, it would be medium lift, short duration to keep it easy starting.

It occurs to me that I have made an "apples to oranges" comparison- It also might explain why I couldn't understand exactly what you were saying.



That's a good way of putting it- I have been in that position many times, including now.



Will do. Thanks for taking the time to clarify.

Andrew

Unless there is something worth discussing, that follows the subject.

If you would like the thread to be over, simply don't view it.

If it were nothing but a pizzing contest, it would be a different story.

Assuming it's a, straight-thru, glasspack variant, yes.

Here is one of my 16" x 3" versions, made by Dynomax.



In this application, they take the "crack" out, which reduces the SPL to below 95 db.

A resonator chamber is/was often part of the OEM muffler, in place of a separate unit, as is done in the above Flowmaster.

The generic replacements on all my other cars, do not. The difference is, that anyone with normal (or slightly impaired) hearing, can easily tell they are V8s.


Make that, the more mixture. The concept of adding fuel, to an existing mixture, is what keeps 91buickman confused.


Have you wondered why, it's called sound pressure level, instead of velocity level?


Exactly.

Norm

Where in this thread do you see me talking about fuel mixtures? Or would you like to bring up another thread from 2007 again?.........Another example of your B.S

I had. About 2 years ago I took a really neat class on electronic music production, and the first "unit" of the class was the study of sound waves, waveforms, and what they actually are, and why we hear them like we do. It was really quite interesting.

I didn't realize, until that time, that when a speaker fires, it creates a pressure differential in "waves" that vibrate our ear drums.

It is, of course, easy for anyone to look it up on Wiki, or Howstuffworks, but to actually learn the material brings you a greater understanding.

The instructor had a large woofer, probably 20 inches or so in diameter, and it was capable of playing really low frequencies. In fact, we sat inside the first sound wave at one point, the frequency was so low.

Looks like I have sort of gone on a tangent- Oh well.
