Hey guys,

I am very unknowledgeable when it comes to exhaust and the differences between them all. Can we have a teaching course on this?

What are the differences between them (chambered, glassed, true-dual, butterfly-valved, etc)

Also, does the exhaust make the gurgling sound on older cars or the rumbling sound on the new cars or is that the engine? And mufflers, I thought were to dampen the sound of the engine only, are they doing emissions too?

Basically share what you know on exhaust systems and how they work.

Thanks.

I have to admit I was expecting at least one response.

The exhaust sound will depend on how far you go with your exhaust system and any engine mods you have installed. That gurgling sound from older cars is more then likely from a large cam'ed engine with exhaust heads and straight pipe (no muffler). If you drive your car a lot and want to hear yourself think... this is not your ideal setup. Mufflers do dampen the sound your engine makes. I could be wrong but I certain they have anything to do with emissions.
True-dual is what it states... Dual exhaust pipes from the engine to the back of the car. No H or X pipes. Most cars today that have "Dual Exhaust" actually have 1 pipe down the mid section of the car that will split into 2 exhaust tips.
Butterfly valves are valves on some exhaust systems that open at higher RPM's to allow more exhaust to flow or to increase sound. A good example would be on Corvettes. If you look close at the exhaust tips you will see 2 of them are actually closed, 1 on each side.
As for Chambered and glassed terms, I'm sure it has something to do with the design of either a resonator or the exhaust itself. I'm not sure myself but I'm you can Google them and get some great answers.

Hope this gets you started

To find out what an exhaust system does from the factory simply remove your pipes all the way back to your headers. That 4.0 in your engine bay will sound quite a bit like a diesel truck. Your catalytic converters are for emissions. Which is why no cats=not street legal in most cars. The mufflers are for noise dampening. Factory exhaust systems often restrict your exhaust and decrease power. Which is why most of us switch to a freer flowing setup. On a factory engine the freer flowing exhaust will allow for a better rumble and might give you a little more power. If you super/turbo charge that small amount of freed up power greatly increases. It's simple the better your engine is able to do these (Suck. Bang. Blow.) the better it will perform.

Best sound in the world.
