Damn, I was assuming the same as the OP here. But after reading the comments, it's obvious that I'm missing out when I zing to my GTS' 7,800 rpm redline. 
I really wish Porsche would build a GTS4.0 RS! Same engine as the other RS cars, but just in a *slightly* more livable package with a suspension one click more compliant than that in the SRS (which is one click more complaint compared to the GT4 RS). No wings, limited aero changes, etc.
Come on Porsche, take my money!

The best way to do this is to make your own out of a 4RS

How ironic to read these posts.. My GT4RS is in hand.. and Boxster GTS 4.0 on way.. all ready a bit familiar with both motors.. but getting ready to do hard comparo of both.. keep both and enjoy 2 diff motors and bodies (but the same exact interior/function).. or instead combine all that into ONE Spyder RS..

Just watched Harry's Garage Review of the Spyder RS. He does a great job of capturing that insane 9000 rpm motor.
It struck me though watching the tach focused clip that the way that engine zings from 8000 to 9000 rpm is the same way that the 718 4.0 zings from 7000 to 8000 rpm.
the 718 4.0 has an intensity and sharpness to it from 7000 tp rpm to 8000 rpm that it doesn't have at other rev ranges
watching Harry's video of the 8000 to 9000 rpm GT3 engine it made me think that the 718 4.0 has a similar intensity and sharpness to it as it approaches redline, but the difference is that it happens from 7000 to 8000 rpm.
I have never driven one of the 9000 rpm engines though so I could be way off, just wondered if the same thought ever occurred to others that have experience with both.

I drove a 991 GT3 at PECLA before I got my GT4. It's a much more thrilling engine. You should experience it yourself.

As others have said, the 9k revver (I had 991.2 3rs) sounds like the engine was only supposed to go to 8k but you go over anyways and it somehow has even more power but also sounds like it’s going to explode, it’s definitely wild
my gt4 just sounds great and much less high strung. I still like the car more even though engine is much less racecar. No one will tell you on rennlist but The 4.0 liter 9k shtts on the mezger tbh. No idea why people even continue to talk about the mezger when we have the 9k Motorsport beast. I get complaining about the size and pdk and everything else of the newer stuff….but the 9k engine is the best motor of anything put in a Porsche 911 and I don’t think it’s even close

) I'm sitting there going 'shift, shift, but the engine still has that extra crazy 1000 rpm to deliver! My 991.1 GT3RS doesn't give me that sense in person although it does give me the aural sense of a 1970's F1 car or something, I guess its the mere 8800 rpm redline?

Spyder RS is pretty much this, without the un-necessary roof! Put on some 19 inch wheels with bigger sidewalls, and you're on!

That's exactly the sense I get watching Spyder RS/GT4 RS videos (less than a week before I get to experience it first hand) I'm sitting there going 'shift, shift, but the engine still has that extra crazy 1000 rpm to deliver!

Took a drive yesterday in a friends new Spyder RS. Still running in so keeping it below 7000rpm. Even below 7000RPM it makes my GT4 sound boring. The 2 engines aren't even close at the same revs. Let alone once you get over 7000.

I'll be bringing a box of earplugs to the delivery...

Earplugs aren't necessary, it's not so much the volume as the complexity and harmony in the tones. There is a real depth to the noise that comes through into the cabin. You would need at least a 10 piece orchestra to replicate anything close to it, while you could probably do the same with the regular GT4 motor with 3 or 4. If the musical analogy makes any sense at all.

One of the big advantages of having that "zing" happen up to 9k rpm instead of 8k rpm is that the gearing can be 12.5% lower and still achieve the same speeds in gear which results in 12.5% more torque to the ground through torque multiplication of gearing. People often make the mistake of comparing torque figures at the engine, but it's torque at the wheels that really matters (which is totally dependent on gearing). So having more torque at the engine really only helps when you're in the "wrong " gear and the revs are lower than they could be in the "right" gear. This effect is easily noticed when you compare the feeling of torque (thrust) when starting from a stop in 3rd gear instead of 1st gear.
