How does the SLP D/D compare to the Magnaflow brand? Do they flow as well? Anyone have sound clips of the two or know where I can access sound clips?

BTW, like I said, my car made 423 RWHP with the cuttout open. It made only 395 RWHP with it closed. So, I have an additional 28 RW HP available with the flip of a switch.

I am thought there was a difference between the factory installed SLP DD and the SLP Performance Parts bolt-on DD. My impression was that the bolt-on version uses a slightly louder muffler then the factory unit, and it tends to fow a bit more too.
