I'm considering trading up to a 991.1T from my 997.2T. Have not driven a 991.1T yet, but would love to get some observations from those who are familiar with both.

Truthfully, I prefer the styling (and in particular the wheels) on the 997.2, but the technology and expired warranty are my key impetus for making the change.

My biggest grievance, other than the technology, on my 997.2 is the lame exhaust note and muted engine sound. Has this been improved on the 991.1T?

Driving-wise, how does the 991.1T compare?

I realize I can answer these questions myself with a test drive, and intend to do so, but would love to hear other opinions.

I recently sold a 997.1 turbo cabriolet and bought a 991.1 turbo s cabriolet. I have spent quite a bit of time behind the wheel of a 997.2 C4S cabriolet, but I've never driven a 997.2 turbo. Here are a few of my observations that you may find helpful:

- The technology in the 991 cars is a huge improvement from the 997.1. I realize that the 997.2 has better electronics than the 997.1, but you may still see some improvement. The 991.1 has everything that I want; Sirius XM, excellent navigation, text messages from my iPhone 7 are displayed on the PCM screen, excellent bluetooth connectivity, etc. I'm quite pleased with the technology. The Burmester sound system in the 991 is excellent.
- The suspension and ride quality in the 991 platform is a huge upgrade from the 997.1. The 991.1 turbo feels very "planted" when cornering, even with PDCC switched off.
- The cabriolet top in the 991 cars is a huge improvement over the 997 cars.
- The exhaust note in the 991.1 turbo is better than the 997.1 turbo, but many people still find it to be muted. It has much more intake noise and it has lots of overrun chatter in sport mode which is quite nice. Overall I think it's much better than the 997, but you may find it to be too muted.

I am enjoying the 991 more and more as I get used to it. It's bigger than the 997, but it drives like it's smaller. You'll understand that when you drive one.

Good luck with your search.

I will concur with Dennis C's observations. I went from a 997.2 Turbo Cab to 991 Turbo S coupe which cost me some...yet I felt I got good value. I particularly enjoy the GT feel of the car 997 iteration which was a substantial improvement over the 997.2 in my opinion...on all fronts - comfort, technology, performance. 997.2 Turbo was a great car, but I felt the 991.1 felt like a car in this price point. Was also the first time I felt the car wasn't "light" on the front if that make sense.

The one additional point that can be made here is that while the 991.1 exhaust sound is better than the 997.2, it can be improved further at relatively little cost with the sharkworks muffler delete. Alternatively many used cars already come with exhausts upgraded. I bought mine as a 15 month old CPO with 4500 miles and a Europipe exhaust with high flow cats already installed. Was an amazing find!

Thank you.

Yes, my current lack of Sirius/XM and streaming bluetooth streaming audio is quite annoying.

Regarding "overrun chatter" are you referring to exhaust burble when letting off the gas similar to the Carrera with sport exhaust? Any upgrade over the vacuum clean audio experience will be warmly welcomed. Not sure why I never pulled the trigger on a simple sharkwerks muffler delete... but I suppose that ship has sailed at this point.

I've been in many 991C2s... absolutely love the interior upgrades. Miles ahead of the 997s. Feel in love with the 991C2S and now the 991.2C2S and was planning on one of those... but with the 991 Turbo prices falling as rapidly they are I think I'll spring for a CPO 991.1 Turbo rather than a 991.2S as I'd been contemplating.... makes more financial sense... and I'm a sucker for sledgehammer straightline speed.

General Jack

Yes, that was a nice find, good job. Its tough for me to spend money on aftermarket mods anymore after being burned on resale a few times (wasn't a surprise).

Dennis C

Yes, the overrun chatter is the burbles and pops when you let your foot off the gas. It's not as loud as the normally aspirated 991 cars with PSE, but it has much more character than the 997 turbo exhaust.

Drove 100 spirited miles in my 15 TTS. I am really in love with this car.

Two biggest improvements over 997TT are pdk and suspension.

I also really enjoy the Burmeister and I have the Sharkwerks exhaust.

i had a beautiful 2012 997.2TT, loved the car. traded it for a 2015 991TTS, no comparison. handling is much better, the pdk is better, interior is better, suspension is better.

no brainer

General Jack

Interesting on the PDK, what did they improve?

Love your Challenger. My dream classic is a '71 'cuda.

Very tough call. I have both currently. Both are modded so not really apples to apples comparison.

My 997.2 is a track and airstrip car, although I can drive it to work no problem which i did today for fun. It is way more visceral and fun to drive compared to the subdued 991 (even tho my 991 is catless with 68 turbos). Major differences are in steering (hydraulic vs electronic), suspension and of course styling. Styling I give the nod to the 991. Suspension the 991 stock is better, but a few tweaks with the 997.2 suspension can make it amazing and actually better overall to track because of the hydraulic steering and better feedback at the track. Although for just daily driving the 991 electric steering is very comfy.

If you want something more refined, go with the 991. If you want something more raw and nasty go with the 997.2.

I've had a great deal of 997TT and 991TT come through shop, and have had had the opportunity to experience them stock and modified. I feel the factory exhaust on the 991 is a bit less muted than the 997, but by no means would I consider it a sound that inspires passion or fun when you put the pedal down. The good thing about the 991 is that exhaust sound/resonance seems to be much less prevalent, so you can run a more aggressive exhaust setup with less impact on the comfort when cruising. For instance, our Catless Supersport X-Pipe System sounds absolutely superb and at cruising speed it didn't show any noticeable increase in internal sound that I could hear.

As for resale, exhaust upgrades should affect that very little. It is very easy to switch back to factory as you don't need to modify anything to upgrade with our systems. We even have a vast amount of Porsche dealers that actually sell and install our products. Worth looking into, as you'll love the potential sound these cars have as does everyone haha.

Porsche just keeps tweaking the PDK and its very smooth and fast.

The suspension is so much better...car more planted and stable vs previous generation.

I have been driving Porsche turbos since 1991...they just keep getting better.

Add exhaust and enjoy...I have over 10k miles in the last year alone.
