First, in efficient mode at idle I'm getting a tapping/ticking/puttering noise. Mostly from the passenger side muffler exit pipe. Doesn't sound like pipes rattling. Unsure if this is a defect in the muffler or installer error on my part. The noise lessens dramatically in S+. Going to go back and double check the clamps and make sure it's not leaking, although I'm not confident that's the issue.

Second, I've ordered a SST exhaust flap controller and here's why. The OEM controller is all over the place. It's not noticeable at stock exhaust levels, but it's painfully obvious with louder configurations. I've been out driving a few times since installation and it's been wildly erratic with how wide the valves are open. It's like it's got multiple personality disorder... so weird. Took the valve motor off yesterday and verified it's installed correctly.

Many were asking about the fitment, and overall, I'd say it's pretty good. It clears all components of the vehicle. The resonators seem to have shifted a bit since I installed and are sitting a bit closer than I'd prefer. Nothing is rattling yet, but made need to adjust a bit soon. The rear exit pipes/tips are a work in progress. The driver's side exit is currently sitting a bit further towards outside than the passenger's side. Adjustment up/down and between the two pipes on each side is easy, but this may prove slightly harder to remedy.

These are all just initial impressions and it's a bit of a work in progress. Relatively happy with the fitment, not happy with the sound yet. I've caught a few moments of a very nice, aggressive idle/WOT, which leads me to believe this system can be what I wanted it to be, but the stock valve controller seems to be actively working against me lol

Bit of a pathfinder mission I've embarked on, will continue to update as things progress.

OOHHHH so prettyyyyyy.

What wasn't quieter was the driver's side valve that was rattling like some metal bones when I turned it on this morning! Apparently with valves closed at idle at certain angles, the valve is loose enough to cause a bit of a racket. When I pushed on the exterior side of the valve (opposite the motor) it would stop. I rolled it forward and it went away. Pushed on it again and it started rattling. Put it in S+ and it stopped rattling and it had no play when I pushed on it under load. It's looking more and more like this is going to be a valves almost always open for me, which is fine. Only time I'd care is in the early morning.

Now I stink like exhaust and need a shower lol

gotcha, now that you explain it, it makes sense. Hope you figure it out.

Not as bad as that, though. Although I definitely had an oh shit moment when I accidentally put the outside exit pipes on the wrong sides hahaha

Strangely enough, the pipe that's supposed to be on the driver's side actually fits almost perfectly on the passenger side, but the other is wayyyy off.

Once I have everything squared away, I'll be giving a lot of feedback to CSZ on the fitment. Hopefully they can make some adjustments in the future and bring a more polished product to market.

Were you able to find out what the weird sound was coming from the passenger side?
