Default Full Akrapovic Evolution Race System vs. Stock (991.2 GT3)

Dealer just finished installing the full Akrapovic Evolution Race exhaust system (titanium headers with deleted side mufflers combined with titanium center bypass) on my new .2GT3.

For reference, here is the stock exhaust (under 5,000 rpm):


Now, with the Akrapovic system (also under 5,000 rpm):


Both sound great, but what you can’t hear from the videos is the immensely greater volume, depth, and presence of the Akrapovic exhaust. Words cannot describe.

I had it on my .2 GT3 as well. Cold start is LOUD but I love it. My neighbors don't love it at 5am however

Seriously - the sound is intoxicating with the full race system. It is surprisingly quiet at highway speeds too.

Spacers on the rear O2's no CEL's.

Are the headers catless, or a lower cell?

Sounds very good.

Nice video because one can definitely hear the difference. Probably one of the better comparisons I have heard on this forum. -Very nicely done

No CEL and this will go on my RS

The Akrapovic Evolution Race Headers are 100 cell. It's been so difficult to keep up with the demand for the Akra exhaust but as of the writing of this message we have them in-stock.

OP, thank you for sharing these videos with us.

Your site doesn't seem to show any products under Akrapovic 991 GT3. Tried different browsers, same result.

Do you have a link?

Great comparison by the way, can clearly hear the difference. Would be great to hear a drive by.

Thanks for sharing!
Loved my Akra on my 991.2 GTS.

Akra was on my short list for the GT3.....but wanted the ability to maintain the Sport Exhaust button depending on mood/location/wife.
So, I'm doing JCR center silenced bypass and valved side deletes.
