Just curious if by reducing the exhaust note whether that cuts power in Sport or Track mode. Any feedback

It may a little at partial throttle (a few HP), but they open fully anyway once you get on it hard. The first time it happened it surprised me!

It might just be me, but it feels like the car jerks forward a bit when the Stealth mode is overridden under WOT at ~4500.
It might just be because suddenly it gets louder, but have noticed it repeatedly.
Neat feature, lol. I like cruising around in Stealth mode.

Off Topic: Everyone likes to make fun of it, but the way my house works, without Stealth I'd wake the baby up every time I start the car. Really a great feature.

I would say no. I ran the same times at rd atl during quiet hour in stealth mode as i did in track mode

Thanks, thats just the info I was looking for. I like the stealth mode because it tends to underestimate the true performance of the car until you really get on it and then all hell breaks loose.

Certainly it does. It was 430 closed and 436 open on a non supercharged ls3. Supercharged even more so. Engine is like an air pump. Hallltach intake is getting big numbers but headers alone no
but halltech and headers would shine.
You have to address intake and exhaust both for best results.

Yes but even in stealth mode it completely opens up under full throttle. Seems like the best of both worlds.
