+1.
My wife had to go across town, so she took my LS.
I was standing in the drive way while she was pulling out, I told her to squash the peddle as she leaves from a dead stop.
OH MY GOD!! The sound roaring out of those pipes was AWESOME!!! I had the huge smile on my face. Loved the sound. And being that Lou (QuiKLs) and I installed the system ourselves, it made it an even sweeter sensation.
After a few minutes my wife called me and said she felt all "Fast and Furious" cause she was pushed back in the seat and could hear the roar of the engine and exhuast. She later told me that she was passing cars every chance she could get to get that power feeling.
Once again, I LOVE HAVING AN LS!!!
