what about a super 44 compared to a glasspack??

 

A glasspack will sound a lot different and possibly a little louder. the Super 44 is a chambered muffler. The Super 44 has a much more controlled tone, not just a listless rumble.

 

i had the cherry bomb muffler for about 6 months an the thing blew out due to rust, sounded decent, but not loud enuff for me! went with a gibson supertruck this time an the thing sounds awesome!

 

my buddy said that when he went from a glasspack to a super 44 he gain a little bit of power...anyone know anything about that

 

I have glasspacks on my 454. When I went from the stock to the glasspacks, I lost a little low end but gained top end. What happened is the glasspacks are pretty much a straight pipe with a little bit of fiberglass wrapped around it. This allows for very little backpressure. A Super 44 is (to my knowledge) a chambered muffler. So the chambered muffler has more back pressure than a glass pack since the 44 actually isn't a straight-thru design. It basically has two or three noise-cancellation chambers that the exhaust gasses have to maneuver through. If I'm thinking correctly, the chambered mufflers have zero packing material. The chambers do all the work. But since not all exhaust gas goes through the packing on a glasspack, it flows better.

Now for the backpressure. When a vehicle goes from a high backpressure design to a lower backpressure design, you lose low end and gain top end power. The opposite happens when you do the opposite. You utilize the low end power more often than the highend power. That's the only thing I can think of.

 

Not neccessarily. Theres a balance point in between where you gain in both.

 

You are correct. I was speaking in terms of just the ends of the spectrum. I didn't include the middle of the spectrum. I was just talking about either a lot of back pressure or almost no back pressure.
