@Ian@Borla can you perhaps clear this issue up for us? We'd like some actual facts/details on how the optional Chevy Accessory exhaust truly compares vs. the S-Type. Thank you in advance!

Let me try this again. The photo is the rear of my car with the stock NPP exhaust (and my great-nephew). The links are to videos on my OneDrive. It might ask about the OneDrive app, but you should be able to just click and watch the videos. They are before and after cold starts.

One thing I notice right off the bat is that all the aftermarket Borla kits I have seen have black heat shielding and yours has a shiny silver on the GM/borla kit. I must say, I prefer the black hidden compared to seeing a giant piece of tin foil in the rear. (I wonder if this was a change only for GM or an update to all Borla kits!?)

I posted this same comment in "general discussion" recently.....and prior to shopping and buying the ATAK for my C8 I watched and listened to every available video showing stock vs. s-type vs. ATAK including Borla's videos.
Video watching proved to be time wasted as I feel there is no way to compare video sound to real world in person comparison.
I love the ATAK. I can dial it as I like....yet I like LOUD the best! Lol.

NPP vs S-Type vs ATAK dB
Thanks for posting this comparison! I have been debating on the S-type vs Atak for a while and this is the best video I have seen showing what the S-type sounds like. It definitely sounds more mellow and deeper than the stock NPP, but not necessarily louder? It could just be the audio of the video though...
The least difference between the NPP and Borla is the first 30 seconds of cold start but even then the Borla is significantly louder. It is difficult to tell from a video - I have never seen a video that accurately depicts the true sound, NPP or Borla.
Having said all that, I know some members who still wanted the ATAK for the loudest sound possible and the ATAK definitely is that.
Here is a response I got from Ian Borla to questions about the decibel level of the various exhausts. It helped me choose:
Unfortunately we don't test for maximum dB level. We use test standard SAE J1492 to measure the volume of our exhaust systems.
The Stock NPP exhaust averaged 86.6 dB in Touring mode and 89 dB in Track mode.
The S-Type averaged 92.4 dB in Touring mode and 101.3 dB in Track mode.
The ATAK averaged 100.9 dB in Touring mode and 104.4 dB in Track mode.

Do you have the numbers for the GM Borla system - like the ones you posted for the S and ATAK?

If you want a noticeable difference from the NPP, get the S type or ATAK. For be it will be ATAK because I think I am still 16 and like the engine music lol.

I just went on the Borla website and nothing comes up for the C8 anymore. Have they been having problems with them and hence the website not showing product for the C8 now?
