I've been lightly researching over the winter, and am curious if anyone has any info or experience with mufflers that flow well, but with less noise than a straight through?

I currently have two straight through 3.5" Magnaflow mufflers on the 1g, but I'd like much less noise. I'm willing to sacrifice a little HP, for example, if the car makes approx 575whp DJ now, a reduction down to 550whp DJ would be acceptable if the noise level was reduced.

Anyone have experience with these?:

Any suggestions of what to consider would be appreciated.

Google search found this(FI has different flow characteristics, but I'm sure some of the theory applies):
