As I mentioned on the original post, we won't be focusing on any of those set-ups but we might have a compilation video with some sound clips featuring sounds like that coming out after we wrap up the last video in a few weeks.

Yes

We do have experience in different arrangements, including fully opened exhausts but due to the regulatory environment, we chose not to showcase those. In general terms, less restriction in the link pipe leads to more power, slightly louder exhaust tone and more turbo whistling noise.

I tried an AWE X-Pipe Center Delete pipe on my 991.1 and it was so loud and droning I took it off the same day, then ultimately put a Tubi Center Exhaust on the car which was just right. I was surprised at how civilized this straight pipe sounds in a 992. Those Turbos really do take the exhaust noise out of the car, unlike the naturally aspirated vehicles.

This is a lot of work and time for Flat 6 Motorsports to do all this, I hope everyone appreciates it and considers buying from your company in return.

I have the soul cats and Akrapovic exhaust but its still not loud enough for me. What else offers the same valve control but a louder note??

Funny. Soul cats plus Akra is deafeningly loud to me on cold start and still too loud for what I want after it’s warmed up. Shows you how everyone has different preferences.

I have the same set up and think it is just about right. Just shows why you have to listen to as many as possible. Tastes are varied.

​​​​​​jon ..Another question ....since you've modded that base model so much. Have u investigated if the rear wing can be reprogrammed to open higher like an S with SPASM?

Yes, we have it still on the car, so feel free to swing by!

A reduction of cells in the link pipes. The only system that might be a smidge louder with valves from our testing is the Tubi but I don't think it would be worth swapping it for that small increase in loudness.

With the valves closed, there's a slight resonance, nothing crazy but it is there. With the valves open it does drone at low RPMs but I suppose to be expected.

I have not looked at programming the rear wing. I was going to go to a fixed wing but decided to just leave it alone for now. We'll be doing a lot of power enhancements after we do the iPE exhaust. We've wanted to hold everything constant so we can dyno apples to apples. We'll be doing intercooler testing, full bolt-ons, meth kit and the Pure turbos as well. A lot more performance content is coming and we'll really push the platform more.

What exhausts you plan to test next? I just installed the Cargraphic on my IPE and wonder how it compares to other aftermarket valved systems like Akra, Sould etc with valves wide open.
