Our LS4 is SOHC and only 16valve......maybe that'* why

sad thing is we don't have any aftermarket exhaust package yet :(

Thats the one diadvantage to new cars / but I can accept it /lol. I love my car and it talks to me. I decyphered the engine growl, and it'* telling me to run over Barney and anything pink.

LS4 is OHV not Single Over Head cam as you stated. Sorry had to correct that.

that sounds sweet. you should do some drive bys and incar audios.

Car is really apart right now but soon I'll post videos of the laser lit purges, machine gun purge and If I have enough nitrous left...A snow storm. Filled bottle yesterday. $50 Good for ten minutes on happy trigger or ? for show purges( we see) And a sound clip of Full WOT Nitrous run. I figure to put my laptop in the trunk and hang the mike between the pipes. I cant wait to hear that. thanx guys

I could swear the drive by sound clip is of the Werks LS2 Solstice?

I would have to think long and hard about choosing between mine and That Solstice Mallet has a version with a */C 440Hp that I'm sure would put this old man in the grave. Satisfied, but dead. I'm sure the recording of the GXP sound is very enhanced by ( as I mentioned ) the computer mike was place only 3 feet from exhaust .

ok here is LS4 with no intake resonator, no exhaust resonator.
The cracking sound is after I took off intake resonator......do I have to reset PCM or something??? I might put it back.....

wow that sounds good i think i blew one of my computer speakers

If only I could shatter windows as I go by. Almost cant wait for the OEM exhaust to rust out and gut the cats and put stainless in!
