Got my exhaust on this weekend. I ordered the CS catback with race pipe. The kit arrived well packaged, and it looks amazing. Its exactly as pictured on the corksport site. The resonator is in the race-pipe, and the mid-pipe is tubing only. So far (pulling it off the ramps and a few revs) it sounds super quiet. I found installation easier in reverse form of the instructions (race-pipe first). Fittment is decent, but I ran into two minor problems.
1. The mid-pipe sits high enough that its hanger is useless, I had to twist the rubber hanger out of the way for it to fit. The two hanger rods sit maybe an inch from each other at most.
2. I had to massage the heat shielding a bit in the area of the rear-most 90 degree bend as it was touching the midpipe.
I opted to leave off the included band-clamp for now (it goes over the slip-fit connection of the mid-pipe to race-pipe), and have not detected any leaks. I'll install it once I get some type of hanger fitting properly on the midpipe. I may also try to find some stiffer hangers, as the stock rubber ones are quite wobbly. I'll post an update once I have driven it a bit.
edit: On this mornings drive the exhaust is 100% non-intrusive at idle, cruising, and eco-friendly driving. Once I give it some throttle and the revs start climbing above 3k, it starts to wail (certainly noticeable, but not obnoxious). Seems to have a little more top end. Some rattling and whatnot from the fittment issues that need some attention, mainly at startup and idle. Probably from heatshield contact.
