but did you die

What I find interesting is your sport cats + OEM catback makes more power than your GT2RS setup with no muffler! That means the OEM catback poses absolutely no restriction - it actually flows better than a straight short pipe!? Am I interpreting your data correctly Fabspeed? If so there are some funky things going on with backpressure requirements for the 992TTS.

The current Dyno results are from our R&D car only, we did have a few backpressure issues when developing the GT2RS outlets which I believe is the cause of what you're seeing. They have all been corrected now thankfully!
If anyone is in the Philadelphia area, come by and we can do your install and get more data for the community!

but did you die

So just to confirm the factory PSE muffler + sport cats still makes more power than your GTRS setup right? Very counterintuitive...

Theoretically, the gains would be consistent, we assume they will be when we eventually test the improved design. We are not in the business of faking or otherwise altering numbers, that is why they are skewed comparatively.

Our website and forum posts will be adjusted as soon as we have rerun the Turbo on the dyno.

I appreciate the transparency in your testing methodology. Either way you slice I think you can say Porsche did a decent job in designing their muffler for minimum restriction.

Treat your 992 Turbo to the finest cat-back exhaust solution on the market. This valved exhaust system is plug-and-play with the factory PSE system so you can turn PSE off for quiet highway cruising and turn PSE on for ripping Twin Turbo sports car sound!

I must have this in my life!

Nice. Are you working on a non PSE unit ie the end pipes would be squarish to match the OEM bumper fake tips

Fabspeed Motorsport

This is fully compatible with non-pse 992's, we include a handheld valve controller rather than what would typically be your stock PSE exhaust button.

I am having the PSE button programmed by the dealer. My issue is that the two round tailpipes are not going to look ideal with the square tips.

I have also ordered my turbo s with with non PSE and was wondering if the current Valvetronic exhaust would be compatible ?

We have not confirmed fitment, but there is no reason that it will not fit! I shot you a PM

Fabspeed Motorsport

Happy to announce we have another 992 Turbo S in for some tuning R&D!

The power and sound after install were truly something to marvel at, updates to come!
