I wish I could but my impatient self forbids me. When I pick the car up, it will have Xpel, exhaust, Ferodo brake pads, motul brake fluid, alignment, GMG roll bar, Schroth harnesses, UV painted rear reflectors, etc. I'll never know how the stock car is/was. I will, however, have an excellent idea on how it compares to the GT3 and it dang better be faster on track.

We plan on doing some independent dynos if time permits with our clients car.
I have attached two dynos, one for the EVO RACE system, and one for the standard EVO system in the meantime.

I highly doubt Akrapovic would do such a thing. They are not the type of company that would fib gains to sell systems....

Dan (wonders why Porsche doesn't buy out this company and implement if true - maybe because not CARB legal?)

Just a point worth noting and perhaps something you can let the supplier know. Most of us who have the 991 GT3 are aware what the symbol on the screen of the dash in the clip is indicating. It can range from something minor to something major but in general isn't something you would like to appear on the screen of your car when you are driving, particularly when advertising an after market product...just a heads up that all.
P.S. Im a big fan of Akrap product....just cant afford it!

It is emission problem here for sure. R-Delete is going to take care of it and unfortunately all other errors you gonna get.
I am gonna contact a dealer and ask if they would be able to flash ECU with this exhaust and still respect the warranty.
To be honest I am really tempted by this system. Not for the power gains as I don't believe in fairy tales but just for the weight and sound gains.

I still can't believe that the stock is open as well. I am not trying to be a pain just curious how it is in fact (like other guys).
Would be very nice to see 4 graphs. Stock valve closed/open. Evolution valve closed/open.

Other 200 cel cats show very similar trends in power gains as the Akra systems. I find Akra's dyno graphs believable.

Akra's been providing the RSR exhaust to the factory team for a while also part of the exhaust on the RS for sometime now too. Most of their business is in motorcycles which is probably why Porsche wouldn't buy it...

I'd probably be more inclined to go with the sports cup version which keeps the stock headers and cats, deletes the side mufflers and replaces the rear muffler. Cost is probably significantly less than the Evolution set up.

Good eye indeed. I am going to try and use O2 sensor spacers (FVD) first. They have worked fine on my GT3 with 200 cell cats and when one of the cats failed and triggered the CEL, the spacers did their job. I realize Akrapovic is 100 cells so it may not work but I'm keeping my fingers crossed. I should know later this month, on my first track day with the RS at Eagles Canyon raceway.
