Hi All

Long time lurker here.... who has now finally converted to an owner....... :D :D

picked up my Ftype MV16 ZHF, ticked a lot of my boxes....colour, pan roof, mileage, owners, etc....
but i had to compromise on the active exhaust button.....
(if SimpleR is about, would really appreciate a PM to help with a little background)

The dealer explained that if i used the dynamic mode, then i would get more noise from the active exhaust note.
(was wet when he took me out in it, so couldnt really hoon it)
have been trying this but am a little disappointed by the volume....

Q,
is there any way i can increase the volume....??
Remap?, anyway to keep the exhaust valve open?

Any ideas would be appreciated.

You could try cccharger.co.uk. They sell a kit that allows you open the exhaust valves whenever you want with a small remote control. Try their website or eBay.
 
LR Retrofits get lots of positive reviews and can retrofit switchable active exhaust for £150.
 
The active exhaust button doesn't buy you anything extra in terms of noise - in my MY18 it opens the valves at 1500 rpm in non-dynamic mode. If you engage dynamic mode the valves should be open all the time - you can tell at tickover by switching dynamic on and off and hear the difference. Maybe your valves aren't opening - do you get extra noise when you go through 3500-4000 rpm?

Whereabouts are you? Maybe a local forum member can give their opinion and demonstrate their level of noise.

And welcome to the club!
 
I can’t remember the fuse number, but in my 2015 V6s it’s in the under bonnet fuse box on the left of the scuttle bay. The fuse map is in the manual.

I pulled the fuse, and it permanently opens the valves, so lots of nice noise all the time!!

However, that’s not what I wanted, so I fitted a switchable fuse in place of the original fuse, and put the switch under the dash on the drivers side. Works a treat, and no issues in 5 years! Cost pennies.
 
On a 2016 reg car, the active exhaust should be fully open when you switch to dynamic mode. Even at idle, toggling between dynamic and normal mode there's a noticeable difference in sound.

The car does learn and adapt to the driving style of your journey. If you're in sport and dynamic, lots of throttle and lifting off, mixed with feathering will generate pops and bangs. This will continue for a while with less provocation until you return to normal driving. Also try accelerating hard and changing up early using the paddles, to make it spit on the upshift. It takes a bit of practice to get the hang of it.

I think it's F43 in the early models, F15 in the later ones.

Hi and welcome, car 26234 in Stratus Grey. What do you want to know?
 
SimpleR
Thanks for coming back, appreciated.
There is a hpi report that i got as part of the documentation that appears to mention a switchable exhaust as a £350 option?

The £350 is the cost of the button as an optional extra. I checked the order form from my V6 where I added the button. Odd that it just says sports exhaust.

You can tell if you have an active exhaust as the valve stubs are visible just before the silencers (engine side). It became standard about a year before your car was registered, so it'd be very unusual not to have it.
 
Thanks for that Mick...
Strange that the list says 'switchable active sports exhaust' £350
But there doesnt appear to be any switch....
Maybe the list is wrong... its from a hpi check
Wonder what the original build spec says....
 
For reference, here's my F-Type without the switchable exhaust button.

That's not to say that the cars don't have active exhaust valves, I think it was an option on the 4-pots and base spec V6, but the S and the V8s had the active exhausts as standard. The button just lets you manually open up the exhausts, rather than the car doing so at ~4000rpm.

You can achieve the same result by pulling fuse 43 / fuse 15 as mentioned earlier in the thread.

Or by switching dynamic mode on to open the valves all the time. That gives you the option run quieter if you want, without having to replace fuses.
 
Thanks lads, appreciate the support...
Tried the 'dynamic mode at tickover test' didnt notice any change in note really.
It does 'roar' on startup, so i guess the the valves are open, but then it goes quiet...
Have just removed fuse 43, it does sound a little louder but havent had the opportunity to hoon it yet so will report back.
Interesting to hear that it learns from your driving style, not wanting to cast any aspersions, (flame suit on), but it was owned by a lady since new, and done 3k pa on average, maybe her driving style has had an effect....

Thanks all so far...
 
I think if you drive it like you stole it it'll soon learn to hang on in the gears for you ....

I am surprised that selecting dynamic mode doesn't give you a noticeable burble, though - mine is very obvious.

thanks for the 'sound' advice.....
have removed fuse 53, and have driven it 'spritedly' for the last week..... now it sounds like i think it should.... :D
thanks gents....

more 'newbie' questions to come.....

but will start new threads for them
