So I am resigned to not buying my 2015 5.0 F-type back and decided to test drive a 2021 F-type 450 today.
Very nice and lovely car but where has all the snap crackle and pop gone?
Even in dynamic mode this car was quieter than my 2015 car was in quite mode, in fact I could hardly tell the exhaust noise difference between normal and dynamic which a real let down having owned an original version.
I will really need to find a solution if I am to buy this version, so have any owners of the newer version found a way to re kindle the excitement in the exhaust department before I hand over the hard earnt for the newer model?

Had a recent discussion with someone who had just sold his F-Type for health reasons. He reckoned he lost two opportunities to sell it because both potential customers said it was just too noisy. You can't please all of the people all of the time! Mike.

Hi Mike, well I am sure for some it is too noisy with the old F type soundtrack I think maybe Jaguar went a little too far quietening the new cars.
After I just signed up for my 2023 car last Saturday a DB9 went past the showroom while I was outside and even though it was quieter than my 2015 car it made me hanker after at least a mid point for soundtrack on my new car.
maybe someone out there has a reasonable half way house fix?
Cheers

Colin,

Maybe just use one of the independents to remap it closer to the original noisy setup? something like this:

Alternatively talk to someone like Swallows as they do a lot of tuning work on F Types

This sounds promising I just wonder if the Jaguar dealers will tune the new map out at service time, it seems some owners have had that actually happen even though they requested for that not to be done.
Maybe need a map file on the laptop to drop back onto the ECU post servicing?

I know some people of taped message to not do that to their dashboards.
personally I have given up on main dealers and use independents so can avoid this as I can actually talk to the mechanics.

There's a number of things happening with exhaust sound over the years. I'll try and remember the details, without looking it all up. The EU noise regs were lowered in around 2017 and again in 2019 I think. In response Jaguar issued a software patch H239 (around 2017/18). This did a number of things, firstly it kept the valves closed, in normal mode, until 1500+ revs, irrespective of the button being pressed and it also reduced the pops and bangs on overrun. In addition, some US owners were experiencing cat failures, due to the injection of unburnt fuel to make the pops and the EPA laws over there mean the cats are under warranty for 7-10 years, so Jaguar would be having to stump up for the replacement cost for many years. Unfortunately, once bulletin H239 is installed (there are 3 parts to it, I can't remember which one is the culprit) it cannot be reversed. The next iteration was mid 2018 (MY19 cars) where the OPF filters were installed in the cats. This also makes the exhaust quieter, but it is further neutered by software which keeps the valves shut until either 3500ish rpm, or when under full acceleration load (any mode)

So, what are the possible solutions. Obviously a remap can be done to create pops and bangs and exhaust systems can be changed (Supersprint is probably the best sounding of the after market exhaust suppliers). But there is also a simpler option to try, particularly on some 2018+ (MY19 cars with the OPF). Remove Fuse 15 (beige coloured under the bonnet) and the valves stay open permanently. This does not work on the 4 cylinder engines (P300) as it will throw a code and go into limp mode. There have been reports of some V6s doing this, but afaik the V8's don't exhibit any problems. Very recent cars 2023+ ish have electric actuators on the exhaust (rather than vacuum) and the exhaust has to be set to open (button/dynamic) before the fuse is removed and the actuator is disabled. (Fuse 15 disables the valves on most earlier V6/V8 too, with the exception of very early cars where fuse 43 has to be removed in conjunction).

This is a huge subject of discussion, just browse 'Jaguar F type Fuse 15' and enter the bottomless chasm of threads lol:

Well I had a search regarding Fuse 15, went to the online manual (proper manual will be purchased soon)
Started by turning on the ignition and activating the exhaust button, lifting the bonnet and removing the fuse box cover and subsequently fuse number 15.
The result is an immediate increase in volume on every start up and a louder exhaust all the time with a little crackle and rumble on overrun at sensible speed, I have not given it the beans yet as it was not fully warmed up at he time.
My impressions are if you want a bit more noise and make the car sound like a sports car with a V8 then full fuse 15 as above that said I do think at the moment it is a very long way off and original sound such as my original 15 reg 5.0.
I am just leaving the fuse out for now to see how I get on before I decide if I go for aftermarket Cat's and Silencer.
To be fair the original could seem a bit anti social so maybe this will be a sweet compromise, I will try to post how it feels driving without Fuse 15 in a few weeks.
Thank you everyone for the input

If you, or your noise meter (passenger), find the 'open' exhaust a bit droney at times after removing Fuse 15 (e.g. going up long hills with the engine under load), then just click up a couple of gears using the paddles, to raise the revs a bit temporarily.
