Active exhaust and dynamic mode

I’ve put a deposit down on a V6 340 base. Late 2015 (65 plate). Could I check my understanding that the engine will, as standard, come with an active sports exhaust. Jaguar’s current website is clear that all F Types have an active sports exhaust (https://www.jaguar.co.uk/jaguar-range/f-type/features/engine-technology.html) but does that mean that a late 2015 engine is the same (at least in this regard) to new units?

Secondly, what is the relationship, if any, between ‘dynamic’ mode and the active exhaust? I recognise that the exhaust valves only open automatically at around 4000 RPM without the manual switch option, but does this happen regardless of driving mode? Thank you.
 
If you are the sort of person considering how an when you will hear the exhaust orchestra playing then I would strongly advocate you find an example with the exhaust switch. If not you’ll rergret it from day 1
I’d also stretch to the S if you can for the many extras it has from LSD, more power, larger brakes and typically much higher spec.
Mine’s an S so cannot answer your specific question
 
I believe a base 340 MY15 would have the switchable exhaust (IE no button) as standard but of course it may have had the optional active exhaust option ticked at point it was made.

First question. Does it have the exhaust button?
 
Thank you for the replies. No it doesn’t have the exhaust button. I’ve driven the F type with and without the button, but both cars were less than a year old and had the active sports exhaust. For me personally, I’m not worried at all that the exhaust sound is muted at low revs and speeds, but when I put my foot down, I would like the car to respond in noise as well as speed. Therefore, the ‘wait’ to 4000 revs isn’t a deal breaker at all, but if the “sports car soundtrack”, as Jaguar describe it, doesn’t happen at all, it probably would be. My question is simply about the age of the car and whether it would have the active sports exhaust as standard.

My second question is simply for interest and about getting to know the car. Put another way, what does the ‘dynamic’ switch actually do? I don’t have the owner’s manual of course, and looking on line has got no further than Jaguar’s web pages that say: “Select the dynamic driving mode to coordinate the vehicle's control systems to contribute to a more dynamic driving experience.” It’s not altogether clear what this means and I therefore wondered whether it could be linked in any way to the active sports exhaust (as well as other things by the sound of it).

Thanks again.
 
Dymanic mode makes the instruments glow red, and tightens the steering, suspension, gearshifts and engine. You can tailor these settings through the touchscreen, but only insofar as "on" or "normal". It also opens the exhaust valves at all revs, not just at tickover and about 4k. I'm sure others more knowledgeable than me can give more detail.

Thank you. I’ve seen a YouTube video in a car with the exhaust switch (which mine doesn’t have). When you switch to dynamic mode, the exhaust switch immediately glows red, to indicate that it’s been activated at the same time. I wonder, though, whether without the switch the same happens (i.e. the valves open) when dynamic is selected.

I believe it does work the same way without the switch. The switch just enables you to engage "loud" mode in non-dymanic, or "quiet" (relatively) when in dymanic mode.
 
If you want a switchable active exhaust there is a company called cccharger who make a modification that enables you to open the exhaust valves whenever you want by remote control. They have a website and the product is also currently on eBay for £118. It is simple to fit and definitely works. I have one fitted my to V6 340 F type and can confirm it really works. If you are not sure call the guy who runs the company, Clive, he is very helpful.

Very helpful, thank you. I’ve checked their website and it definitely looks the quickest/cheapest way of achieving the louder exhaust note when the active exhaust hasn’t been activated. I’m hoping I won’t feel I need it, as when I drove the F Type without the switch I actually enjoyed the relative quiet when we were on the motorway, which is where I will spend a lot of time. When I booted the car, the active exhaust kicked in and it provided an exhaust note in keeping with how I was driving. All good.

Having checked with a Jaguar dealer, it appears that on the base model, the dynamic mode operates independently of the active exhaust. This is unlike a car with the exhaust switch, which is ‘plumbed in’ to the dynamic mode to automatically activate the active exhaust when dynamic mode is selected. Driving the car will prove it one way or the other (picking it up next Saturday).

Thanks again for all the help and advice.

Interesting. My MY18 manual says "Note: The active exhaust feature is switched on automatically if the vehicle is being driven in dynamic mode." No mention of different behaviour with or without the switch. I await the results of your experiences! ;)
 
Thanks scm. That’s really interesting! My vehicle is MY16 and a different engine, but the principle would be the same and I can see no reason why it would be different. I take it you don’t have the exhaust switch? Either way, I’m happy as long as the exhaust responds to the way I drive.

I do have the switch, and it works as a "loud" button in non-Dymanic mode and a (relatively!) "quiet" button in Dymanic mode.

I think I’m going to have to draw stumps and see what the car actually does in dynamic mode. Having established that my car will have the active exhaust and that it will make all the sports car noise I want when I drive it like a sports car, then I’m happy.

Looking through other threads here and elsewhere, there is certainly some confusion over this. I think (but can’t be certain) that the link of dynamic mode with active exhaust (switch or no switch) is only on the V6S and above. I can’t currently find anything to disprove what the technician at the dealership told me, i.e. that on the base model, dynamic mode and the exhaust system are independent.

There may be owners of a MY16 car on here that can definitively say either way, but until I pick up the car it may remain a bit unclear. I really appreciate your info though and will return to this thread with my findings!
 
Sorry - can’t help as I have the S, but for sure I can overide whatever mode the gearbox or dynamic is in and open or close the valves at my discretion.

Good for silence on the motorway or coming home quick at night through partly built up areas

Great to drive like a sports car with all the noise without having to use the engine hard And end up going too quick
 
I have a 340 base MY16 bought new and without the button. I intentionally left it off the options list because when switched to Dynamic mode the valves open at any speed. Also tightens the steering, seems to harden the damping and the engine mapping seems more agile. So if I want the noise enhancements at low speed I switch to Dynamic, couldn't see why I need another switch to do that. To get the pops and crackles you need to go into Sport as well and then you get the full soundtrack on overrun and the most glorious snort when using the flappy paddles under hard acceleration. My favourite sound is however under normal mode, hard acceleration when the valves seem to open anyway and an ungodly howl ensues. Haven't regretted not having the switchable exhaust button ever.

I think the confusion has arisen because early F-types didn't have the active exhaust as standard on the base model so it either had to be added as an option (with the button?) or a V6S ordered.
 
The early f type S you could start the car, just press the exhaust button and the valves would FULLY open.

On the more recent models if you start up and just press the exhaust button it doesn’t FULLY open the valves. You have to put it in dynamic mode to do that.

The button only really useful now to turn DOWN the noise when you’re in dynamic mode.

I had a 2014 v6s before I got my R and when swapping a few of the dealers where explaining this to me. I actually prefer the functionality of the earlier F Types when it comes to the button function. It’s no real hardship though, I just put into dynamic mode every time I drive the car for the full noise.

Very helpful indeed and very clear. Thank you. It aligns exactly with what scm said in an earlier post and with the MY16 owner’s manual. I now need to educate the dealer! Thanks again. Picking the car up on Saturday ...
 
Hi , my F-Type is the same as yours, but a year older. I too looked for a S model, but in the end, purchased a non S model from a main Jag dealer about a month ago. My thinking was, as I won't be track daying my car, is the extra cost that the S demands worth it to me, the answer was no. On the day I had to make up my mind, my dealer arranged an extended test drive is each model, it was this that made up my mind, and I purchased the non S. At low revs it is a sensible car, as much as a sports car can be, but in Dynamic mode (with the selector in sport) the car turns into something else - Doctor Jekyll and Mr Hyde, with all the theatre that the F-Type delivers so well. Do I regret not buying a S, not so far, I'm loving my car and it is a wonderful introduction to the world of F-Type ownership, and anyhow, a year down the line I can always trade it in for a F-Type that's a little more potent!
 
Hi All. I'm new on here so please forgive my naivety.

I have a 2014 F Type 3.0 S and suspect the exhaust valves aren't working correctly. The valves themselves seem to be working fine and are open on start up and idle but then close when revs pick up which I suspect is correct functionality. However, the issue I have is when I turn the Dynamic Mode on the valves also don't' stay open. The car doesn't have switchable exhaust mode function/button.

Does anybody have a similar issue or know what the issue may be?
