I've had mine for a few years, now, and it still sounds good and works well (whatever that means) but I think it may have a small leak/crack at the rear Y-split, as there is a lot of carbon deposit in that area. The slip-joints seem to be holding up fine.
The piping follows pretty much the same path, but it is 2.25" before the rear Y and the bends are smoother. The muffler sits where the old resonator used to be, and it is 2.25" all the way through, unlike the choking, restrictive resonator it replaces. The small cans at the rear are, I think, resonator cans. Overall, the system is certainly less restrictive than stock.
I've always loved the sound. A subtle intonation of power, rather than a ricey rasp.
I've also loved the low-end gains. Peak, high-rpm hp gains not as good as some other systems, but overall I think it boosts the performance where this car needs it most.
My humble, biased, basically unqualified observations.
