Whats everyones opinions on these? I'm looking for deep mellow tones. I hate the raspy noise associated with most tuner cars. After looking through the threads I think test pipes tend to give more high pitched levels so I think I'll steer clear of that.

I'm thinking Megan muffler, and perhaps modify some generic high flow Magnaflow cats while I'm at it. That or look into Borla if its not too expensive.

Is there a reason many people go with HKS and other brands over Megan? Seems it isn't talked about too much on here.
