When I got my R last March, I pulled fuse 15 the next day. I LOVE the sound. Then just weeks later DMeister burst my bubble by posting about the problems that might come up with fuse 15 gone.
Fast forward for the last 10 months and I live with a quiet car as I rarely get it above 3500 rpm to hear the throaty sound.
I know about the ASR valve controller ($500) and how easy it is to install (thanks again DMeister) however, I told my wife I wanted to spend almost $500 to make my car loud and I did not get a positive response (even though I reminded her that the exhaust valves are always open on her 2017 Corvette and its noisy) I'm trying to suggest my 3 kids chip in for the ASR for next christmas.
Wachuko, pull fuse 15 for just a day or two and that will convince you you need to hear that R sound permanently.
pulling the fuse opens the valves permanently and gives you the same sound as using the ASR controller or the same sound as hitting the little exhaust button on the console to open the valves above 3500 rpm.
The valves also open on a cold startup in your garage, but close right away when putting it in gear.

Thank you. That sound at over 3,500 rpms is intoxicating!! I wished I had that from low rpms as well... when the wife is not in the car, of course.
And yes, that initial sound when I fire the car in the morning, oh my... so sweeeeeet.
Great Choice! Personally, I think having the ability to remove the stripe is a good thing if you ever want to...
I bought my 2024 75 new as well and am pretty happy I did. Sure, they depreciate but meh... don't care. I had the opporunity to get a 2018 SVR but really wanted the digital cluster and the improvements made to the car right up to the 2024 model. IE: Mechanical suspension enhancements, rear e-diff, digital dash, pixel headlights, chassis tuning, coolant pipes.. etc.. Not that I think buying used is bad but I like to know exactly what's happended with the car.
What is the benefit of it? Not having to press the button on the console? And remembering last setting selected? Trying to see what is the benefit besides remembering the last setting I remembered.
I can tell you which is the one that I am doing right away. That dreaded Auto Shutoff. Pulling that plug today.
To be clear, the benefits are —>
1) With stock you cannot under any circumstance achieve the glory of what we are talking about, as the car will never allow the back valves to be open under 3500 rpm. Doesn’t matter what buttons you press.
2) You can achieve having valves open throughout the entire rev range if you pull the fuse 15, but they will always be open (which may not be what you want, and which sorta defeats the purpose of having a switchable exhaust). Then there is the Claws Out Mode solution that was put together by someone on the forum. This allows you to virtually pull 15 and virtually replace fuse 15 using a bit of electronics trickery (i.e.: All without needing to physically touch the fuse, which is clearly convenient to be able to switch from full open to full closed when you want). PROBLEM: Both of these approaches have risks, as outlined in those 2 links to those threads I provided you.
3) The ASR allows you to have the valves open for the full rev range and to not (go back to stock), all with the push of a button. THE IMPORTANT PART: It achieves the equivalent of pulling fuse 15 without the risks. I would also add that it is a polished product that just works perfectly (as one would expect). The Claws Out Mode talked about above sounds good (risks aside), but it had a few idiosyncrasies that need to be understood, that could be confusing, etc…
Make sense? For more clarity refer to the information I provided.
Aside from convenience, how does the "valves open" mode on the ASR mediate problems that might occur with fuse 15 removed over the same time period?
Hi there,
I totally get the confusion, because it is exactly that ;-0 lol
All the raw information to be able to answer that is certainly in that Fuse 15 PSA thread I linked above, but I wouldn’t wish that on anyone…Good total info in there for sure, but it’s a lot to go through.
This question was more or less asked in the following thread (that I also already linked above) —>
If you look at posts 20 and 28 in this thread you will see my responses, which is essentially a full summary of the totality of issues discussed in the PSA thread..

Now I fully understand the value add. Thank you for your patience explaining this to a newbie. I had no idea these cars had GPFs... I associated that with diesels engines. So I was kind of lost, as I was reading, when there was mentions of regeneration. I had a BMW X5 diesel and kept thinking "what the heck?", as I was reading the thread.

Hey, no problem man. I’m happy for you about your new car and I’m happy to help. We all try to help around here where we can. Pretty good community here I’d say.
Yeah, GPFs are definitely beyond diesels at this point. Fortunately these F-types don’t really seem to suffer as badly sound-wise from the presence of the GPF as some other brands. It’s still pretty good, especially when you do the ASR business, so it seems to be one of the better implementations.
I’m planning to take things up another notch by replacing the stock back box exhaust with a solution from Velocity AP that still has the switchable valves, and that fully integrates with the stock valve actuators (i.e.: Will work seamlessly with the ASR). Apparently this really opens things up a lot. That is feedback I’ve received from a few people on the forum that have done this on these newer F-types. Based on the feedback I’ve received I’m expecting it to be pretty epic. It’s already pretty good with the stock box as long as the ASR is in play, but I think the aftermarket back box is gonna take it to exactly where want it to be.

Letters have faded. If it was used, I would have not cared. But I want them to fade under my ownership, lol.
Man, there is something wrong there. That should not be doing that on a car this new. I almost wonder if someone didn’t put something on it that caused that to happen…Cleaning product of some kind, or something…I would totally tell the dealer that needs to be replaced.
How long have you had the car?

It’s the cheaper one that I went with. It is plug and play. The more expensive one has an invasive install that requires you to splice into the wiring harness of the car. Not for me personally. It can be programmed to the Homelink buttons on your ceiling there for a nice integrated feel.

Makes a lot of sense… It is a new car, doubt they did something similar to that in the video. But any cleaner could have reacted with the paint on the cover…
I went to the dealer today and the will replace it with a new one.
Wanted a splash guard for the front. Searching the forum, found what folks are doing. Using rear XK Quarter Edge Trim in the front of the F-Type. Looks like a great fitment and aesthetically correct.
