1 year with 2015 Type R

. Over 4000 RPM, the valves are always open regardless of the switch position. The trick to driving around in school zones without the backfire, is to keep the revs under 4000 RPM and never allow the engine to provide any braking.Easier for me to do with the manual transmission, but may prove challenging with the automatic.
In my 2016 R, it’s easy to drive in stealth mode and get no pops and crackles. Dynamic off and D, easy on the throttle.

On my car, the valves are always open at idle regardless of switch position. You need a bit of engine speed to create enough vacuum to close the valves. Before you conclude things are broken, have the engine running at 2k rpm when you inspect the valve position.

There's no doubt mine are open all the time. If I left off the throttle at 1500rpm and coast it pops and crackles.

For fun car types I'm not a fan of AWD.
In my case, I wanted a solid high HP V8 before companies stop making them.
The R has that in spades.

As for weight, I'm impressed with how much lighter on its feet the car feels with forged wheels and the Wortec rotors - removing 100 lbs of unsprung weight helps noticeably. The lithium battery and stop start battery delete will save you 50lbs, reducing the overall heft to like 3700 lbs. If we can find a few other porker parts on the car to swap and shave another 100-200lbs, I think we'd have a pretty nimble beast...
I do understand why modding is a fun hobby though.

The active exhaust is in loud mode at startup, then will change to quiet or normal mode a few seconds after starting the engine. It's very noticeable that loud start followed by quietening.
Then when driving in normal exhaust mode it remains quiet with no audible pops and bangs.
It goes loud when the exhaust bypass opens which occurs above 4000rpm in normal mode and throughout the rev range when the active exhaust button is illuminated (selected)

According to the Jag Active Exhaust document (which I've found isn't 100% accurate), the valves are open for "Start & idle < 1100rpm) and closed for 'Fast Idle > 1100rpm" for normal mode. For loud/dynamic, it says the valves are open for both conditions.
However, in my V6S with squeaky exhaust valves, I can hear them flipping open/closed around that engine speed, even in Dynamic. (I don't have switchable active exhaust, just active exhaust.)
Boulder, if you want to PM me your email address, I could email you that document (~1MB), since you couldn't view it from my Dropbox for whatever reason. It's pretty interesting, and would answer some of your questions.

I think my modding days are pretty much over. It seems like I spend a lot of money and end up with something not as good as I started with. For example, I had a Porsche Turbo I modded to over 600HP by a really top notch company. That screwed up the ratios in the transmission because now the first two gears were too short and the suspension mods made it great on the track but it trolley tracked on the street. In my experience, factory engineers are damn good at what they do. The exception is probably light exhaust mods and adding safety stuff like roll cages and electrical cut offs. It also tends to screw up downstream resale.

On the other hand, the work they did on my sound system is terrific. I was listening to Khalid tonight and it sounded great.
Doing a 1000 mile road trip this weekend. Great car on the road.

What work did they do on your sound system?

I personally could do without, let alone the cracks and pops being a big reason I bought a F-Type.

I finally popped in a CD and was amazed at how goof the bass was, compared to normal radio. I put in Beastie Boys "Licensed to Ill" and was floored at how much better it was. I think it's pretty clear that whatever processing is in the radio (normal and satellite) is just way off the mark.
