In-Depth 992 Carrera Exhaust Series (Flat 6 Motorsports)

Dyno runs are in the video or linked on the product page (post above with the video). In fairness, most of the systems have some resonance around 2K RPM with the valves opened (the stock exhaust does) but the iPE seemed to amplify the booming tone/deep sound a little more than the others. For me, it wasn't a big issue as I cruise with the valves closed on the highway. The 992 (at least my base model) has a lot of plastics that vibrate with certain frequencies. Mine does a little with the stock exhaust.

John, I wish to thank you for the outstanding thread with all the advice, testing and videos you've compiled, thank you very much. Secondly, I wonder when you dyne the cars testing the exhausts, are the valves open (sport mode)? It would seem to me they would be for maximum gain. Just curious.

We don't have any plans to. We've wrapped up with the exhaust testing for this scope and will be moving on to test the IPD plenum, CSF intercooler and start upgrading with the Pure Turbos and Meth Kit. Since we have a shop and have 992s in all of the time, I'm sure we will be able to capture and release future sound videos of different set-ups but I don't believe we'll be able to pull of what we've done to date with the living with impressions and dyno results. Whenever I settle with a set-up on my car, we might do a similar video with that. I'm likely going to run the Kline valved system with competition link pipes. I would run any of them personally but think that one fit my preferences the best.

I’d be interested to know which of these setups should have come from the factory.
I got to drive a 991.2 and it sounded pretty good when you’re getting into it, it didn’t need much more unless a person was after a cup car sound for the street.

John you have put a TON of work into this thread. Tell me you are getting a few orders from it - I sure hope so. And people here buying pipes SHOULD support this thread with a purchase and not buy elsewhere for a few dollars difference.

I agree wholeheartedly with Dr. Collie (fellow Targa owner) and will be reaching out to John at Flat 6 soon to discuss purchasing one of the systems tested -- he did us all a great service with his in-depth reviews, and I will not purchase from anyone else. Thank you, John!!

@Flat6Motorsports So the Akra Ti system is $2100 more than the IPE Ti system. The Akra comes with tips and no silencer, and the IPE vice versa. Neither of them have an X-pipe. Where do you think the extra money is going as far as Akra? Which of them do you think has less drone with the valves closed? Do either of them sound different at WOT ?
