BORLA Challenge exhaust


Ive been looking at cat-back exhausts for some time now, and am finally ready to buy for my CE LT4. I have narrowed it down to two: the Borla Challenge (with Xr-1 resonator) and the Power Effects. Didnt like how quiet the Corsa was, and the flowmasters were a little more primal than I was looking for.
I know alot of you like the Power Effects exhaust, but do any of you have any experience with the Borla "Challenge" in particluar. My CE is a daily driver and I could put up with SOME resonance, as long as its not TOO terrible. They both are priced the same, around $1300.
I love the looks of the Borla, and I have heard that they are of good quality. Any comments would be appreciated!
Thanks
ROSS
