I don't think this has been answered before or even asked. I was just curious, is there a difference between a muffler that has deflectors "like a flowmaster" and one that has steel wool packing "like arospeed"??

Thanks all in advance for the input.

Yes there is. One has deflectors and the other has steel wool. Lol! J/k. I think the differences in the materials the mufflers use to muffle sound causes a distinct difference in exhaust tone.

Yea exactly, all they do is shape the sound differently. The steel wool helps mellow out the sound. It smooths it out, absorbing high level noise and deepens the note. The deflectors in a flowmaster dont really absorb any sound, they just make the exhaust gas take a bunch of different paths and get it all turbulent to make it sound more agressive.

Thank you both, you have answered my question. And since you both did it, I can't mark either one of your answers as correct....lol....sorry.

Thanks again..

Ummm...Neil, I think you're a little wrong about the flowmaster-type exhausts, the reflectors aren't just there to make the car sound more aggressive, it's more a matter of utilizing the inherent traits of sound waves to force them to cancel eachother out. In the case of flowmaster exhausts and the like, certain tones are cancelled out and the lower, more aggressive tones are preserved.

Good call man, I was just about to post that.

Exactly how active noise canceling headphones work :)
Those things are the best :biggrin:
