Thanks so much for putting this video out Joe!

Its a muffling system, so its not super efficient, but other than that, what exactly is "hobbling" the system? (I assume hobbling means preventing it from producing power at the engine potential).
It would be nice to have some reasoning tied to your argument(s).
i.e. There is nothing intrinsically wrong with using a 50mm inlet section on an exhaust system. Theres nothing intrinsically wrong with an id reduction on the suction side of an exhausting system, particularly if you are accelerating into an expansion chamber. There isnt even a necessary detriment to bends, open transitions, or even obstructions in a system, think pulse tuning.
For someone with a background in fluid dynamics, what would you say are the take aways, other than "the inlet is 50mm, theres an id reduction to 48mm and there are three chambers with a velocity stack on the final low pressure outlet". Cuz none of that means anything to me if im tasked with deciding if my stock exhaust is performance compromised.
All that being said, I dont dispute that this designed can be improved on, I just didnt hear any arguments about failings in the present design. I just hear a description of the current design, in a tone that implies, "this is bad".

Show the inside of the Fabspeed muffler, and we can judge what the differences are versus OEM.

[@Alans63]

Thanks so much for making this video!

[@asuna981s]

Nice video, but what about the oem PSE? Should be almost straight bypassing all this restriction, no?

[@deep6thisdeep6this92]

i would like to see the innards of the FB models too.

[@erikkulp8819]

That's what I was thinking.

[@DavidZ123]

do it

[@JuanAdam12]

Not to mention the comparable year 911 exhausts so we can see an apples-to-apples comparison. Otherwise… I guess we just take his word for it.

This is very, very interesting - thank you.

[@SU37]

Wow, thank you for the info

[@carlryan808]

Great video! please do this for the 718 GTS/GT4 system

[@alexandred5302]

Great video ! Want to look inside PSE for 981 🥰

[@Chitown388]

ok, now we know what's limiting the Boxster/Cayman. Other than saying Fabspeed has been doing stuff, what's it doing to address that limiting factor?

[@dmh11185]

Mega! Thanks for the inside info on our fart cans!

[@FabspeedMotorsport]

Anytime!

[@caominh2874]

I love this kind of video. Please do for 971 generation Panamera, and 982 718 Boxster/Cayman

[@FabspeedMotorsport]

We'll get right on that!

[@derktheterk]

Do we know what the sport exhaust from Porsche looks like? With a 981 Spyder I'm curious if it's still as restrictive as what you show.

[@TheCj71984]

What was that green tape for ?

[@curvetrcalinga]

Still looking for a high quality header that is CARB approved. I’m in the market for a header that will pass CA visual inspection.

[@FabspeedMotorsport]

Hi, we are working on getting CARB approval for some of our products. We are unaware of any header on the market right now for 987-981's that is CARB approved. CARB approval is a VERY expensive and long process.

[@HORUS9]

Can fabspeed do a similar video for the facory headders on the boxster/ cayman !?!?!?

[@FabspeedMotorsport]

Absolutely we can! Stay tuned

[@HORUS9]

@@FabspeedMotorsport awesome I'll be looking out for it!

[@dvdlbck]

Is the catalytic converter separable from the muffler without cutting?

[@FabspeedMotorsport]

The primary cats are, the secondary are not

[@timwilson9120]

You failed to mention that the 987 has four catalysts and one is in your demonstration OEM muffler. Removing any of the four is not in emissions compliance and at least a Smog Check failure in California.

[@FabspeedMotorsport]

While it may not pass California Visual inspection, if using our HJS catted headers, you will pass emissions testing as they meet or exceed EPA compliance standards.

Thanks so much for making this video!
