I'd like to put a new exhaust on my 2026 C8 Stingray with Z51 and NPP. I used to have a Harley VRod with Screaming Eagle pipes and a TRX. I have to say that I'm underwhelmed with the stock exhaust.
I live in a subdivision and really need to be able to maintain the ability to be as un-obnoxious as possible when necessary. I do flip the NPP valves open as soon as I start driving. This is a fun car for me, not a daily driver.
The Corsa Variable seems to be the correct choice? It can be quiet, but twice as loud as stock with the valves open?
But, I feel like I'll be missing out if I don't go with the Borla ATAK? I've had friends with exhaust delete and that was just way too much to exist around every day.
Can I get opinions? Can the Borla ATAK be civilized when it needs to be?
I have the Atak and when I put it in tour mode it is quiet. Almost as quiet as the stock exhaust in track mode. Cold start ups though are brutal though.
You can't go wrong with either, really depends on tone preference.
I personally prefer the Corsa valved set up but Borla is a great option as well. I find Corsa to be raspier but does the best job of mitigating any drone. The ATAK set up is aggressive but can be tame with the valves closed.
We have a ton of actual hands-on experience installing different set ups - feel free to give me a shout to discuss

Had the Corsa on my previous E-Ray, and it's a great exhaust if you want louder than stock while maintaining the valves. In Tour, the Corsa is about the same volume as the stock NPP in Track, but you can hear it through the entire RPM range. It sounds like the car should have to begin with, not obtrusive, but just loud enough you know the engine is running and so you can shift by ear if you're driving in manual mode. In Track, the Corsa is LOUD without having a bunch of drone (there's just a little bit of resonance at around 3-4K RPM if you have an HTC and are running with the roof up and rear window down).
Put on Corsa high flow cats combined with your NPP you will be happy 👍
That's what I did and although it's not as loud at the Borla ATAK, it's enough for me--deeper rumble at idle, nice pops in Z-mode on upshifts, and burbles on decel. It takes a couple hundred miles to develop those sounds, maybe less if you drive in Z mode alot.
...and you made the best choice! The Borla S is the best of all of the others. With your NPP system you can run quietly or wind it up to very loud..really loud. I wouldn't get the Borla Atak model, the S model is superior.
You have to ask yourself...do you prefer a deeper tone? If so do the Borla option. Corsa I feel is more appropriate for the car given the exotic nature of the design. Would love to go over options and what I have in stock with dealer pricing @Niebs
If you're looking for a more affordable option I would strongly recommend you look at the Level Up dual mode catback. I do have a $300 discount code on this option with gloss black tips, bringing it down to $2999.99 shipped. It is a deeper tone similar to Borla Atak. What I like most about it is it's got more snap crackle pop on engine deceleration vs the Borla and Corsa options, and it has heat shielding in critical areas for better heat management. Dropping it down to 2nd gear getting to a stop sign you get a wonderful symphony of gurgles and pops. The system simply has more character than others, and with the valves open it's louder too!
Thanks for all the replies guys. Sorry for the late response. I was locked out of my account. My VPN caused some problems.
I wanted to do the Borla ATAK route, but the quality control of the tip lengths pushed me away from that and I wanted the deeper tones. I found Yonristic and also found the detailed review of the system that wasn't too happy with it.
I have received the system and the customer service to date has been 100% personalized and not AI. I'll leave a review of everything after it's installed. It's at the mechanic now.
