This is with the high flow cats. No faults codes.

@Jnosol - yeah agree with your statement, just something close would be great though as I am sure something will come about. Having a Ls3 Na and the sound is incredible as well as previous exp with Porsches

408 to the rear wheels ? How without a tune ? 385 best I have seen stock.

ANYC

Baseline was 377 to the wheels.
408 to four wheels, I have the dyno graph to show it.

With New headers and high flow cats.

Maybe I mis-read. You are claiming 31hp at rear wheels with just exhaust?? Um well I switched to 93 octane and now I'm getting 100 extra hp. Lol.

ANYC

There is the dyno graph... 408.11 HP. It's a dyno jet so the numbers might be a bit high, but the important thing is the percentage difference which is a 8.22% increase.

Jnosol

It's not far off at all. The 991.1 with Fabspeed Valvetronic makes 23whp mid-range and 10whp at peak RPM. Turbo cars (991.2) are way more responsive to exhaust mods, so 31whp isn't crazy talk. The OEM 991 exhaust is very restrictive, compact space, lots of bends, and must meet noise/emission standards.

I take headers to mean the pipe from the cylinder head exhaust ports to the turbo - is that what you mean here?

Impressive!

Yeah, what Fabspeed replaced is just one part long part. The cylinder head through the catalytic converter. They looked at OEM parts and saw how restrictive these pieces were and found ways to improve it. With PSE, the muffler is straight pretty much through when open so there was no need to make any changes here. This means that the 31HP gains can be achieved with just one part! For the 991.1 this piece costs $3k. So I think this is a really cost effective solution.

ANYC

Thanks, Stephen!

Dodaleca

Thanks for the info - I initially assumed this was only a cat back system downstream of the turbos.

Thank you, ANYC, for working with us to bring our 991.2 Carrera exhaust suite to life!

John,
That sounds fantastic. What does it sound like with just the catback?
I just placed an order on a 991.2 C2S and the sound is my only complaint so I'm planning to address that--but I'm not interested in the headers. Would love to hear the catback alone.

John@Fabspeed

Hey, this is Mike in Marketing. Thank you very much! We did not create a replacement muffler for the PSE setup, at this time at least. We found that the factory muffler is basically a straight exhaust when the valves are open and does its job quite well. To replace it would be a good sum of money for similar weight, performance, and sound.

We focused on greatly improving the header design and increasing flow with the Sport Cats and Catbypass Pipes. Can I ask why you wouldn't consider upgrading your headers?
