chambered vs. regular muffler elims?

[Vettefan87]

What is the difference between them? I know one is chambered, but what does that really do for sound and what not?

I have installed an Allen chambered cat back with no mufflers. This system has a baffle built into it, it has a great sound and cost $500. I did have to do some trimming on the tailpipes to get a good fit.

I am not spending over 200 bucks for these mufflers, so that is kind of not an option for me...

I think Heidi has a chambered exhaust system on her '78. It's a Shark but I think she wrote about the differences in a chambered system and a "regular" system.

Yeah my brother payed 130, or something I think and his car sounds pretty nice. If there was someway I could make it a little quieter then pretty much open exhaust I would, but I don't even want to drive the car with the way it sounds now...

I don't know what muffler eliminators are, and I do have chambered exhaust on my 78. I really like it. It is loud, not as loud as open pipes (and I drove an older Camaro with a 350ci and straight headers no pipes for a short time) but it definitely gets your attention at acceleration. I like it loud.

The difference I noticed between my stock system of 2-1-2 and mufflers and chambered...certainly was the noise level...but the quality of the sound is what had me grinning from ear-to-ear! My 78 now sounds like a beefy, muscle car. It had more low end torque (which I like) and the sound was moderate during gentle acceleration but at WOT or spirited acceleration she roars!
No matter what she's doing, when the engine is running, she sounds cool.

I think mine is just to loud. I like it loud, but at WOT, look out, I am breaking noise laws and such. I thought about the chambered, but didn't know if that would make it louder then just straight pipes.

Do you have straight pipes now?
I think chambered offers a little more resistance than straight pipes, I also feel they modify the tone of the sound coming out the end. It seems more "rumbly" to me as the sound is rolled through the chambers. (sorry for the girl-description)

The purpose of mufflers is of course to muffle sound, but they also create back pressure which an engine needs to operate properly. The design of different systems will change how sound and exhaust travel through them and these design differences will determine how it sounds and the amount of back pressure for the engine.
Straight pipes have little back pressure and an open channel for the exhaust gases and sound to flow out of. Loud.
Chambered exhaust has a little more resistance against exhaust flow and changes the sound as it passes through the chambered section.
Muffler designs change the direction and sound of the exhaust gases several times within its casing before it is allowed out the tailpipe and so the sound is lessened in addition to creating more back pressure because of its restrictions in relation to directional flow of exhaust. Various manufacturers of mufflers have come up with designs that offer different levels of sound while still providing back pressure.

More girl-y exhaust/muffler descriptions by me, but that is how I see the exhaust systems of vehicles. Hope you were able to understand what I was trying to say.

Sorry for the dealy in replying I sort of forget this thread was here. Yes I do have straight pipes right now. I sort of figured that the chambered ones would have a little more backpressure then just straight pipes. So I think I might order those tonight, so I can make some more vids .

Okay, someone is making too much money here! First the TPIS headers, then the 1.6 roller rockers, now the exhaust...

Send some of that my way!:L

It is called I am in debt . What else would I spend it on???

Good point, you're going to spend it anyway so you may as well spend it on something that you're going to enjoy.

I hope that I can pay cash for the LT4 when I finally sell the 'Vette and Camaro. If I can't pay cash, I may go for a very small loan or wait a few months to get another 'Vette.
