I will be comparing the 2 exhausts...
The CorkSports system is good, very powerful, but is a little too loud for the driving that I do. I'm in the car a fair bit, and sometimes I don't want the noise, but want the power. It doesn't drone like people suggest.
A bit of a catch 22, but from what I've noticed so far, the CPE system is quieter with what seems like the same power. Obviously a free flowing exhaust will give more power, and I can only assume until I put it on the Dyno that the Power will be slightly less.
Having said that, I might be surprised.
