Exhaust Note difference between L99 and LS3?

I know it is hard to describe sound but for those that have heard both, what is the exhaust note difference going to be between the L99 and LS3 at startup and idle? Obviously once AFM kicks in and the engine is running at 4 cylinders, the exhaust note changes, however is there much of a difference between the two in the other area's considering it is practically the same engine? I saw those pictures of Scott and the team with the headphones on so he might be the only one in this forum who can answer this.

My guess is there will be no difference when all 8 cyls are running. The Cam is a little more mild in the L99 so that could change the "sound" of the engine a little. But I'm betting the exhaust notes will be pretty damn close to each other.

when cruising you wont even notice it (you might notice the lack of a tone due to half the sound being created).

Scott has said already they are working on the regular sound as with the AFM, it sounds slightly different than the LS3, not bad, just different.

honestly as long as it sounds strong and sounds mean when you get on the throttle, i could care less how it sounds when im cruising.

I remember reading one of scott's posts that said they had to change up the exhaust on L99. When 4cyl mode chimes in it is said to make a funny noise...so he said it would be slightly more resonated.

I imagine that the exhaust will be a bit quieter on the L99 than on the LS3 Camaros because of what a 3.1L V4 would sound like.

Ditto, but I dont want mine to drone all the time. I only want the growl when I WOT so it will be a CIA upgrade for me, prolly K&N.

Cut the mufflers out and run 4" tips out the back, or turndowns if cost is a factor, that shouldnt prompt any check engine lights

I actually don't mind that the AFM will be quiet when cruising. It would be fun to mash the pedal next to some unsuspecting Mustang owner just to give them a jolt.

LMAO couldnt agree more with you. Chevy is going to have so many lawsuits from mustang owners. The camaro is going to break so many wanna be poser muscle car mustang nubs.

Or let that mom in the mini van talking on her cell phone know that she shouldnt be in the fast lane. (people just cruising in the fast lane is a serious pet peeve of mine. Especially when they make me break my cruise control. Errr)

Check into Corsa...they sell mufflers that are tuned not to drone.

I think the real issue is that you don't want to hear everytime the engine goes from 4 to 8 cylinder mode. If you have a loud exhaust, every time you give it a little gas to pass someone, you would hear it fire up the other cylinders, and then as soon as you let off, you would hear it drop those cylinders. I would imagine that would be annoying.

not as annoying as twin cutouts dumping right off the headers for 2000mile roundtrip

Well, what I mean is that it might not sound like you expect or would like in 4cylinder mode. Also, I think it drops into and out of 4 cyl. mode pretty regularly as load changes and depending on the change of tone it may be kind of annoying difference instead of a steady sound. Then again, maybe it is not that big of a deal.
