Borla atak...a little too raspy for my taste. I like the S type which is what im putting on mine. But if you want that really loud mean aggressive sound. Atak is the way to go. Like the above said you wont be disappointed

I have to agree with Sean5.0. I have the RTR mufflers and they suond AMAZING! I originally had the Roush mufflers, which from what I read, are very similar to the Borlas. It was too raspy once you get into the higher rpms. I would go RTR.
Here are two sound clips of mine with the RTR mufflers:
