Secondly, I've seen some information that suggest the early version of this engine sounded phenomenal but changes were made in the production exhaust that "corked" it. No surprise there really due to all the regulations OEMs have to abide by. Long story short, after market is often the fix for these simple issues. Just look at how many people change their exhaust with the twins.

Yeah you might be right about the clip quality and sound regulations, but I'm not hearing a lot there that sounds special. Maybe all the references to the flat plane crank and 8000+ RPM redline made me expect an exhaust note that sounded more exotic.

Sound is subjective, but to me, the exhaust clips to the new Camaro SS that @2016 Camaro SS posted sound better... more rich and textured. I'll obviously wait to hear the final product in person though.

I think it sounds great, but the best car I've ever heard is a supercharged 550i with header. Second best is the current Aston V8. Most mustangs sound OK. I do like the FA20 with an EL header.

Im pretty sure Ford alters the headers and exhaust system to give it a more "american" flat-plane crank noise as opposed to the traditional euro i.e. ferrari sound.

That being said, you can definitely hear the latter at the top of the rev range in the video clip, the flat plane design by itself will cause a higher pitched sound

Assuming the firing order was similar to a fezza, all you'd have to do is play around with the exhaust manifolds, at some straight pipes and there you go... you have your very own "GT350 Mustari" lol

Ever heard an M5 with a Meistershaft exhaust or a straight piped LP640?

If you haven't, I bet you a beer you'd change your opinion lol

I have not. Well, I've heard an M5. I also heard the owner cursing because it was in limp mode at the track. Don't know the exhaust on it. Most people at the track care a lot more about open exhaust than sounding good.

I have always preferred the V8 sound to the V12 or V10.

Check out the Nurburgring footage and you'll see what they're talking about with the change in sound. Most likely the older test models didn't have resonators yet (the GT350R keeps that configuration by the way).

As for Ferrari sound mentioned in your previous post, this car will never sound like a Ferrari V8. Ferrari crankshafts have connecting rods that alternate up-down-down-up, where as this one goes up-down-up-down. Ferrari V8s also have separate throttle bodies per 4-cyl bank, so they act like two 4-cyl engines attached to one crankshaft. This engine is all 8 to one throttle body.

It's not as refined as a Ferrari, certainly doesn't create the power per liter of one, but it's a damn good step for Ford. I'm stoked.

Also, looking beyond the motor, the handling seems to be at least on Laguna Seca Boss 302 level, probably far beyond.

Good info. I'm 100% sure this will crap all over the Boss 302. Steaming, flatulent, wet crap all over the Boss 302.

Well I called out the Laguna Seca specifically for a reason. That was the track mustang to define all track mustangs until now, and it was quite good compared to most cars of the time.

[EAGLE5]

Yep, it's amazing where performance is going. Up up up! I remember when idiots were paying obscene markups on the Shelby GT500KR. It's a shame that we don't have Top Gear anymore.

I'd love to see one of these with:

RHD (because Japan)
Akrapovic Ti exhaust
ITBs

But every time I even dream about a RHD Mustang the weight and cost turns me off, and I think LS-swapping an S15 Silvia would be a better choice for a Japan-friendly "muscle car".

[EAGLE5]

There is a RHD Mustang now. I don't know if there will be a RHD GT350.

[Porcupint]

Have to remember, this is a 5.2L flat-plane crank. It's not going to sound like a Ferrari.

[EAGLE5]

They make a 4.5L V8. That's not much different from a 5.2L. Firing order matters, of course, as do a bunch of other factors.

I do want this car, damnit. Why can't I be a billionaire?

Ford Japan doesn't have the RHD ones up for sale yet (I've also been watching for the new Focus RS), but the prices for imported US cars are crazy here, especially since they are supposed to be tariff-free. LHD Ecoboost Mustangs are $36k+. The V8 versions are $46k+. And that's at current exchange rates. At 100 yen to the dollar it's more like $57k for a V8.

If they don't make RHD GT350's, I suppose someone could always engine/suspension swap an Ecoboost 'Stang.
