I've been looking at the various F-Type models over the last week, and my only remaining concern before pulling the trigger is...the noise.

While I love it, and it sounds AMAZING, there are times when I'd want to drive it "quietly". Leaving the house for work at 7am, leaving work at the end of the day and not wanting to light up the car park with crackles and pops, commuting home on the highway at 10mph in stop and go traffic, a Sunday morning drive with the wife to get coffee on a quiet back road.

I'm open to all the different models, The V6, V8, the S, the R, the newer P340. Are there significant noise differences between these models? My budget covers up to about a 2020 P340 ( ~$40,000 ).

Again, I LOVE the sound, just don't want to end up hating it when I don't want it.

Thanks for any advice, you all have been so helpful on this journey!

 

The problem is startup - the exhaust valves are wide open then close after 2 seconds, but that is enough noise to wake up your household and neighbors in the morning!

The V8 R is like a bomb going off when first started.

The quietest will be a base P340 V6.

You can ask Chris at VAP to design a tune to remove the overrun pops, bangs, and crackles like I did, but you will still have the loud startup. It will also keep your catalytic converters from being prematurely destroyed. Most on the Forum love the noises, but there is a small number of us that don't.

Let us know what you decide!

 

Some of us with the newer version of car have installed an ASR valve controller that allows for the valves to be kept open all the time more safely without pulling fuse 15 (which has been established as being problematic for newer cars having a GPF in the exhaust).

That product actually affords the opportunity to start your car with the valves remaining completely closed throughout the entire startup, assuming there are no issues with keeping them closed on startup. I don’t use that feature, as I don’t need to do early morning starts, but the option is there.

So far it has been a fantastic and polished product that works very well. The install is not invasive at all.

 

@DMeister Do you have a link to the product?

 

Super helpful, thank you! I had heard that if you put the car in drive immediately at start up the start up sound drops off quickly, is that true?

On the subject of the tune, is that something that can be done at home by me? Or does it need to be done by a professional?

Thanks again, this is the only thing holding up my purchase at this point. 🙂

 

Yes, putting into drive or reverse will drop the sound, so you get a shorter loud sound until you select the gear.

 

And the car will purr quietly if you don't put it in Dynamic mode, and keep the revs below 3000 (which is easy to do if you're not heavy with your right boot).

 

This is exactly what I was hoping, is this the case with the V8 variants also? One of the cars I'm looking at is the V8 R model...

 

This is the one I installed on my 2024 R, but just be careful to select the right one for your variant on their website. Contact them to be sure etc. if ya think it is something you wanna go ahead with:

Here is an install guide I put together:

https://www.jaguarforums.com/forum/f...-guide-291495/

It’s a very polished product. Mine is programmed right to my garage door opener buttons on the ceiling for a nice integrated feel.

What I like is it is not an invasive install at all. Completely plug and play, no wire splicing involved, etc…You could remove it and never know it was installed if need be. It works great.

Hope that helps

Cheers

 

Here’s the link for the main ASR page…Just select English and select your model F-type etc and it should give the options…

https://asr-component.com

With the newer F-types like mine there was some confusion around there being 2 different models for it, but one was not working and the other was (the one I got) or something…Don’t believe that confusion exists for the older version like your car, but again, confirm with ASR.

Cheers

 

Yep! The V8 is really schizophrenic - a ***** cat when driven leisurely, and a roaring snarling beast when you put your foot down.

 

@FTypeInTheSun Yes, easy DIY for Stage 1, just state what you want in the order in terms of noise, etc. You upload your ECU file and then download their tuned version. They send you everything you need with instructions. The Forum members are always available for help. Just make sure your battery is fully charged and on a charger/supply unit (ie CTEK) while doing the tune. Stage 2 and 3 just require lower and upper pulley replacement and new belt, but still DIY. https://www.velocityap.com/product-c...jaguar/f-type/

@DMeister Thanks for the link - that product will definitely solve the start up explosion issue, bravo!

@scm So true!

 

Just a quick FYI, I believe the earlier cars control spring loaded exhaust valves with a vacuum pump. The later cars (I believe 2018+ but I could be wrong here) operate the valves electronically. I don't know about this valve control gadget, but my bet is that it would not work if you're shopping for earlier cars. Don't think there is much you can do with the early cars being they are vacuum driven. Embrace the bark.

 

That’s a good point, but if I take the SVR as an example…I just selected the SVR on that website for ASR that I posted above and an option came back for it. My understanding is that the vacuum actuation only stopped some time in 2021. The SVR production stopped prior to then, no?

I know what you mean though. That is a bit confusing.

 

Maybe, dunno the years, but if I understand things correctly, if your car had a vacuum pump the valves will always be open until the car starts and the vacuum pump runs (valves are spring loaded). Might be able to control it independently later but unless it can fire the vacuum pump without the car started, you will get the loud start (my 2015 goes to work trying to close the valves right after startup, but it is a few seconds of chaos until vacuum builds )

 

The first couple of model years used an electric vacuum pump. The next few years deleted the pump, but used engine vacuum to actuate the valves. Later still, they switched to electrically actuated valves. I’ve lost track of when they made these changes.

 

Electric valves were on the facelift cars from 2021+ in North America. Everything earlier than that, including the SVRs, were vacuum operated.

 

A very left field comment, bear with me.

I found my sweet spot when it comes to exhaust noise on my V6. One valve open, one shut! It produces a raspy, exotic Italian sports car sound and NO drone. I figured it out when I had the exhaust looked at over the summer and realised one of the valves had been stuck closed probably from when I bought the car while the other was open all the time for a year as I pulled fuse 15.

I had both valves manually opened and ran the car for a month. It was far too much noise and droning for daily driving! I had to stuff the boot with the car cover while waiting for an appointment to reverse the mod. Anyway, I've been back to one valve open now and I just love the pitch and sound level. If I ever want more noise, removing the luggage cover gets all the noise I could ask for into the cabin.

I reckon a lot of people have theirs set up like this and don't know. The give away is visible soot on one tail pipe only after a spirited drive.

I could have the valves replaced or the whole backbox swapped but honestly, the car sounds just perfect to my ears as is so I'm good.

I have what is the loudest of the stock models, the 2017 SVR. It's raspy and angy and I am very conscious of my neighbors. I simply start it as normal (LOUD), then after the initial BRAP it quites down quickly. I drive out of my neighborhood in normal mode with the valves closed and it is quite quiet. When I leave my neighborhood, if I don't get hard on the throttle, I'm up to road speed (45 PHM speed limit, but if you do less than 55 you're getting run over) while still being quiet.

This is a stark contrast to the guy with the Audi S4 that lives on the other side of that main road, down the street. I hear him leave for work every morning. The Jag is not like that unless I do it on purpose.
