Jump straight to the explanation: 1:23

Good sign when the owner is passionate enough to do the in front of the camera work

[@mr10secondGT]

Passionate. Incredible. I will definitely support them. Great video from an enthusiast.

[@seattimetv]

Best in the business especially with GT3 headers!

[@klstrucker930419]

Now I understand why porsches are so expensive 😆😆

[@roadmantop3769]

Fantastic passion, love from the UK

[@frtorres87]

Great work, I’m a big fan of your products.

[@sgttombailes3380]

Outstanding work guys !! HooAh !!

[@peterassel562]

Good videos but coming from down under I always keep thinking this guy is a snowbird from Miami trying to rush to the golf course with the golfing cap on LOL.

[@Sean_Farmer]

On the stock exhaust, what is that piece that sticks up at the top which is labeled "chamber 1"? Does it just alter the resonant frequencies?

[@FabspeedMotorsport]

Correct! The first chamber is used to reduce unwanted resonant frequencies most people know as "drone"

[@PointShiftDrive]

what kind of pricing can we expect for the rear section? also will it pass CA smog?

[@FabspeedMotorsport]

Our muffler bypass exhaust is already available starting at $2,295.95! The rest of the product suite is still being designed, but take a look at our previous GT3 products for ballpark pricing.

[@jerrytang5787]

Does the USA GT3 have OPF/muted exhaust? How does it sound comparing to EU models?

[@FabspeedMotorsport]

1:50 Yes the USA models do have an unmonitored GPF/OPF filter, it's right after the catalytic converter and looks like the same part.

[@FreestylerAlbert]

OPF filter? I thought just the EU versions will have the OPF filter, the US versions should be without that.

[@FabspeedMotorsport]

Just like the 718 GT4, the US versions have an inert GPF filter. So the physical structure is still there, but the precious metals that filter the exhaust are not there.

[@FreestylerAlbert]

@@FabspeedMotorsport thank you for the answer!

[@ivanmiller6378]

so what happens when the valve is open

[@FabspeedMotorsport]

The exhaust travels straight through the H-Pipe

[@ivanmiller6378]

@@FabspeedMotorsport So how can you guy’s improve on that? With let’s say stock cat’s is it even possiable

[@FabspeedMotorsport]

@@ivanmiller6378 Great question! By altering the design of the muffler we can change the tone of the exhaust, particularly at lower RPM's. We will also use an X-Pipe instead of an H-Pipe which has been shown to improve power and give a smoother exhaust note. There may also be power to be had by upping the diameter from 2.5in to 2.75in.

[@kevin5716]

Will it possible that your exhaust affect the torque in the lower rev ?

[@FabspeedMotorsport]

@@kevin5716 Yes definitely. Headers should give us that.
