My akra rear with challenge sport pipe (HFC's) sounds sick... it's not obnoxious, but it's a deep aggressive tone with almost no drone in the cabin at all.
Do you have any sound clips or can you comment on previous setups you may have had with your Challenge x-pipe?
I have the Challenge as well, but with OEM exhaust and it's a little raspy, which I expected. But, when shifting (DCT) from 1st to 2nd, especially when car isn't quite warmed, the car sounds lazy, the shift is more pronounced and sounds prolonged, if that makes any sense.
