I see. Thanks. Borla doesn't offer a "touring" version for the C8 on their website. So what they are saying is that the GM Borla system is quieter then any of the ones offered on the Borla website. Disappointing if that is accurate. I see (it was on either this or a related thread) someone else got a contradictory statement - that was between S and Atak. Was that ever resolved?

No problem. As to where the GM version falls in line, that was never resolved. I'm one of the ones that was told it sits between the S and Atak as far as it's aggressiveness. FWIW, I am the only one so far that has posted direct documentation from Borla themselves to confirm that statement. There was another poster that got it and says it sounds good. I won't have mine in hand until Tuesday now, most of my dealership is out with Covid until then.

Randy,
This is a little of both. It is at the higher end of the S-type sound level so it is almost an ATAK if that makes sense.

Check out what the Borla video says at 6:16, about valve positions. This is for the S and Atak. I wonder if it applies to the GM Borla?

I have it. All they did was valve relearn, no issues at 300 miles so far. Mine was delivered same day NY enacted their new exhaust laws and even the dealer was unsure if they could install it. It's a noticeable difference. I run it I n sport and everyone notices the extra sound and decelerate growl. I went with GM solely for no issues. The carbon tips in GM version are different and nicer

It's Def enough for me. Again with it being the most expensive exhaust ever purchased just for sound and looks id still do it all over again. 😀Extra HP was last on list of wants. I'm more than happy with the power. Good luck.

Do any of the Borla "Touring" line of systems have valves to control the exhaust volume? I did a quick look at their site and did not find any. But the GM Borla system does have the NPP valves. So does the statement that the "GM version would be equivalent to the Touring version..." apply with the valves open, or closed?

@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!

Picker her up yesterday. Hearing it first hand, it sounds amazing (actually gets very loud in track mode). I would say that it's not as loud as the atak, but louder than the one s type I've heard. Not a lot louder, but also has a much deeper sound. I definitely don't regret getting it, but it's definitely not quieter than the S type, IMO. Also looks much nicer with the CF tips than the regular Borla with CF tips. I'll post pics today after I wash it from the 500 mile trip back home last night

I love how much deeper it sounds. This is probably the best explanation I can give...I got home at about 11 last night. Within a minute (probably less) of pulling in, my neighbor came outside because he said he could hear it coming and wanted to see what it was, lol. He didn't know i was getting a new vette. He has a dodge challenger with some bolt-ons (and a pretty loud exhaust, nice car). After fist bumping me, he said that he felt like he was the guy who's exhaust was pissing off the neighbors whenever he would come and go, and said I might be that guy now. Also asked about the exhaust because in his words, "There's no way that's a stock system"

Are you able to post a straight on pic like this?
https://www.corvetteforum.com/forums...post1605120958
Does this GM version have that silver look through the mesh on the back? Not sure I'm crazy about that look.

The mesh isn't silver, but i do have it wrapped. Mine will eventually see some track time once it's broken in and i have a little more time in it (first time driving a mid-engine). I like how the Borla mufflers are visible. I can see why some wouldn't like the look of the silver or wrap coming through, just wasn't a big deal for me personally.
