I can tell you that they sound amazing with the borla 3" catbacks. although under the hood of my sisters it says LS6 on the strut tower. Maybe its an 04-05 V thing

Well, the LS6 was used in the CTS-V until 2005... It's a 5.7 liter engine... The LS2 began in 2006, and it displaces 6.0 liters, and most of them made 400bhp...

I just want one.


End of story.


Time for a raise and promotion at work so maybe I can afford it...because everyone needs 3 cars, right?
