US here too - I went from an 18 R to a 22 R a few years ago, overall much better car. Yes the exhaust is slightly muted - it isn't constantly popping and banging quite as much but if you pull the exhaust valve fuse (which I did on day 1) - it's still way more than loud enough and still bangs pretty consistently on demand with the pedal tap once you get the knack... it's just not as obnoxious as the pre-facelift

I honestly thought I'd hate it because I loved the sound of the 18... but honestly I love the 22. And everyone I take for rides comments on how insane it sounds both from the inside and outside. You won't be lacking for noise

Edit: I have a ton of videos, both driving and static of the exhaust noise, if it's helpful

 

Are you aware of the emerging info that pulling fuse 15 on these cars is not advisable? There is a whole thread on it here somewhere. Without getting too deep here, it has to do with the presence of a GPF in the exhaust (which your car would have). There are safer options to achieve the same thing without pulling fuse 15 and adding the involved risk of problems.

In any case, I just wanted to mention it just in case you were not aware…

It is interesting to hear your comments about feeling the newer car is noticeably better. I’m guessing it likely is mostly to do with the ride, the improved suspension setup, etc…I’m really pleased and impressed with how these newest F-types ride myself.

I also agree that the new f-types are still pretty darn good sound-wise so long as you can have the flaps stay open safely with a proper valve controller like the ASR a lot of us around here are using. And then if you really want to take it up a notch towards getting it closer to the cars of old, just replacing the back exhaust with an axel back only solution can make a huge difference again (despite the presence of a GPF)…

 

Oh interesting - I didn't realize! I knew pops and bangs in general are never great for the cats but didn't realize it might be an issue for the GPF/OPF as well - do you have any resources you can link on potential issues and the better solution? I've had it pulled for about 3 years now and I know others who've had theirs pulled for similar time and luckily no issues yet - not to say there won't be in the future!

And quick sanity check - are we 100% sure US market post-22 cars have the OPF? I've found conflicting info on this, I've driven a 22R in the UK for a week and it sounded very different from my US 22R.

And yeah - handling is the big area that feels different as well as acceleration (I suspect a combination of both the higher power and wider rears, especially when I switched from P Zeros to PS4Ss). I like to drive twisty canyon roads with a lot of gusto and it feels way more confidence inspiring and planted. I will say though - I've twice had transmission overheat warnings on the 22 when really thrashing it and I never got it on the 18 (went away pretty quickly with a calm cooldown for 5 minutes) - not sure if it's just the 8HP struggling with the extra power

 

Apologies for a quick thread hi-jack:

For those running the PS4Ss what pressures are you using? Same as the P-Zeros, or do the Michelins have a different requirement? I run mine at 38 psi cold.

Thanks for any tips.

 

I wouldn't necessarily take my advice but I always run mine low - around 32psi cold. I am in a warm climate though (California) and always do spirited driving so they tend to get pretty warm and raise pressure very quickly for me. I find higher pressures too crashy for my preference with the F-Type and call me a conspiracy theorist - but speaking with tire specialists I believe the higher pressures on the door jambs are primarily for emissions cycles to try and raise the efficiency, not for performance. It'll also increase wear on the lower pressures of course, but it's a trade-off I'm OK with

 

Yes! If I'm just going to be eating up the freeway, then 37-38. For my day to day driving, I'm at 31. Years of racing taught me that most tires do best around 29/30 cold in a track environment so they would be at about 34/35 when warmed up. Some tires were as low as 24 cold. Either way, the recommendations on the door are for fuel effeciency and tire longevity. When I'm driving for fun, I want grip.

 

I also like 38psi cold for the MPS4S.

 

I have mine on 40 but they are 21's.

 

Okay, well, good thing I mentioned it. I believe the GPF was introduced some time in 2022 MY. So I guess it’s possible you don’t have one? I suppose your observation of the difference between your US spec and the UK spec one could be evidence that you are okay? You’d have to find out for sure I guess. In my case, I have a 2024 so it’s guaranteed that I have a GPF filter.

In any case, here is the major thread where all the discussion started. If you’re having trouble getting to sleep some night it will be perfect to read through this ;-0 —>

In that thread there is talk of the ASR valve controller some of us are using to safely keep the valves open. I link an install guide for it under that thread.

Hmm, interesting to hear your comment about overheating your transmission. Can’t say that’ve experienced that, and I don’t recall seeing any other threads on here about that. Weird.

 

I think I've read that the GPF was introduced during MY19 (though I'm prepared to be corrrected on that), and I'm not convinced there are really many differences in the MYs between markets, other than catering for specific legislation.

 

I’ve seen it mentioned that, at least in the North American market, the GPFs only got introduced at some point in the 2022 model year. Thunderdump has mentioned this a few times.

Perhaps 2019 is for the European introduction of GPF?

 

This is correct. The North American market did not get the GPFs until MY22 and it was only done for product/assembly line simplification as a cost-savings effort--there are no emissions requirements to have it here on gasoline-powered vehicles. But it is cheaper if you build them all the same. Other markets, including the UK, have had them since MY19.
