Any exhaust sound clips of L99 in 4 cylinder mode? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Searched youtube and couldn't find any. I assume it sounds like rice in 4 cylinder mode.

Actually, tuning the exhaust note was very important to development. It will sound different, but it shouldn't sound bad at all.

Hmmm, that's a good question. I honestly don't know

yeah i agree i hope it starts in 8 cyl mode then goes down to 4

It's in V-8 mode until it's driving a constant speed on a level or down-grade surface, then AFM activates....at that time there's really not a "load" on the engine so sound difference will be very minimal.

I havent noticed any difference in exhaust note, if you could compare it to anything its almost like when you stomp the go pedal , its like a transmission kicking down from 6th gear but its the engine doing it not the tranny, if that makes any sense

I would imagine it would be like my wife's Tahoe, if it weren't for the info center you wouldn't be able to tell that the engine had dropped to four cyl. mode. The power is still there when you jump on it, but you can't tell otherwise. As far as exhaust note I'm not sure, we haven't changed the exhaust on her Tahoe yet, and with the stock exhaust it is not noticeable.

I've listened to a few Chevy/GMC trucks with aftermarket exhaust and there was no audible difference.
