Rev Match on manual 991.2 GT3

This thread is really about the rev matching though and that ripping snappy noise from the 981 was better. It just was.

It’s a matter of personal preference whether you like the pops and gurgles, which as another poster said, is presumably done by fuel remapping to cause some unburnt fuel to get into exhaust? GT3 never does this, I believe.
Personally I don’t like the pops and gurgles, which are essentially artificial and unnecessary and also draw unwanted attention around town. GT3 more honest.
When I had GT4 (and Spyder now) I tend to drive with auto blip on, as it does help smooth out downshifts if you’re not a heal-and-toe master (I’m not) but sport Exhaust button OFF, since exhaust already sounds just fine without it and it’s more honest without those pops and gurgles.

I definitely felt the gearbox, and drivetrain for that manner, start to come alive after 600 miles. Just warm her up.

Obviously I am not the only one having the same experience. Coming as well from GT4 this was my biggest disappointment. I drove my car first time last week for about 300km. I liked the torque down low, you can`t compare it to GT3, like the engine has 50% bigger displacement. This makes as well the gearing much much better. But then the down shifts with the rev mach. I was really disappointed. Keeping the revs below 4000 for the first 700km.

With respect to blipping, how much are you expecting whilst keeping the car under 4k?

what i meant is that there is about 50% more torque between 2000-4000 in comparison. Maybe not that much on paper, but that is how it feels. I had always issues with the log gearing on GT4. I am not aware of the GT3 ratios but I bet it is pretty much the same. Nevertheless in low RPM in GT3 I don`t have the feeling that there is something missing

Where I actually miss it is when I’m rolling up to a stop sign or red light in 4th gear and slip it into 2nd or 1st before stopping. It’s those moments when the sound is really the only thing that matters and the 981 was better. I’m past break-in so I can grab a low gear and have it jump to higher RPMs. The noise is not as raw.

Ok, understood. So we are talking about the 'blip' and how exhilarating it is when you are really on it and you slam it down a gear. But OP has only taken their car to 4k rpms. How much 'blipping' are people expecting when you keep the revs below 4k?
What do you mean by 50% bigger displacement? GT4 is 3.8 and GT3 is 4.0? Thats 5%.

Heh-heh. The sound is underwhelming street driving while on break-in, isn't it? Anyhow, there are several threads on it, just search "exhaust" or "muffler bypass". Me, I am waiting for my first track weekend to decide if I want it noisier, or if it sounds just perfect blasting around a track full throttle. After break in, there is a nice baritone that comes on at and beyond 4K rpm when the cams change, then the scream as it approaches 9K. Not sure I want it any noisier.

well with my GT4 even below 4000 the blip is more raw. From what I’m gathering, gotta go with an exhaust change. Just trying to figure out whether to do a center bypass or go with the whole header change. Going through the forums, Dundon appears to make the most sense as you gain somewhere between 25 to 30HP but not sure I want to go that complicated. Maybe a Sharkwreck or GMG

Nice car! Miami Blue is one of my favorites!!
Am at the track, have been here for 2 days now. The sound of the car with the PSE is GLORIOUS!!. Pops, burbles, baritones, screams......... a whole orchestra and you've got it all. If you track the car, I would suggest staying stock.I am. Some tracks have a noise limit, and aftermarket exhausts can make you exceed the limit. If it is mostly or just street use, then yes, look into BBI, GRP, etc, for the louder sound under street driving conditions.

Hope you are having a blast. Yes Laguna Seca has a noise limit but that is the only track in CA that I am aware of that limits it. I mostly drive Buttonwillow and Chuckwalla. No limits there. I am counting the miles to get to 1000 so I can open it up
