The center section has an x-pipe design for that incredible high pitched sound and their quality has gotten a lot better. I will be a guinea pig and test out their titanium carback, when my car comes. I’ll weigh it against the stock and also try to get a dyno done. I have attached a couple of pics. You can see the welds and build quality of the new titanium exhausts are way better than the initial ones.
I'll be here to help with that when the time comes

Just my opinion but was curious as why most choose the center muffler bypass over other systems.
For me it was a few things.
1. Sound is the main priority. Wanted to liven it up a little bit without it being obnoxious when wanting to drive around in "wife" mode.
2. Looks. I like the single wall tips better than the stock ones.
3. Cost difference of course.
4. Potential warranty claim when going full system to include headers.
Don't really care to debate if my opinion is right, wrong, accurate or not, you asked. That is why.

Yes. Ran RSS on my 997.2, 991.1 and now the 991.2. Absolutely loved it on the 997. Never sounded quite as good on 991.1 due to non-Mezger in my opinion. I've only had it on the .2 for a short time, but what I've experienced thus far it sounds great!

Warranty is a big one. Also, if you are tracking the car, I've seen repeatedly where aftermarket cats fail due to the heat and abuse of track time.

Why do people constantly refer to tracking a GT3 as "abuse"? The GT3 is a track focused, purposefully track engineered car from the factory. Tracking a family sedan is abuse, a GT3...not in my books! Sure track-use places added stress on various components (vs. purely street use) but 'abuse'?

How’s the fit and finish? Deep sound or a bit more high pitched compared to others? Thanks.

Have the RSS on my .2 right now. But only 200 miles and have not been above 5500. I wish the tips were larger and car is now done for the Winter but need more time to give a definitive answer. My GT4 had FVD LT Headers and their Valveless exhaust and it was one of the best sounding exhausts I have owned. I need time to adjust to the GT3 exhaust because the sound is quite different. So verdict still out for me.

I live in CA.

So a LTH setup will not pass emissions.

Overall fit and finish his fine for me. Perhaps not to the same level as an Akra system, but ok for me. The tips could be a bit bigger as Jimmy-D states although still good. I have the ceramic coated (I think that's what it's called) finish.

Need more time with it (<100 miles so far) to give a more meaningful review.

Dundon under the Christmas tree (accidentally received two left bypass pipes, receiving the correct part tomorrow), the product is really beautifully made, my tree has never sounded this good!

Couple questions - Is this the longer tip iteration??? Also - do you find it high pitched or does it have some good bass to it???

Higher pitched sound for the RSS

Regular tip. They are doing the longer tip for the .2 as the rear diffuser comes out a little more. No high pitch at all. It is a growl. Maybe if you also did the side muffler delete it would go higher pitch but this does not. In non sport mode when the car shifts really early it sounds very similar to stock.

Just did a really nice 250 mile run with it. On the freeway and through town it was great. Wife and I could carry on a conversation and listen to Xmas music. When we got in the canyons, sport mode on you just want to roll down the windows and listen to that music.

I am very happy with my choice. On my Turbo it took three tries to get the right exhaust. I nailed this one first try.
