so yesterday for my birthday my girlfriend decided to by me a flowmaster exhaust for my ls. i have wanted an exhaust for a very very long time but have never been able to get one because we just had a baby and have to spend our money a little more wisely. but anyway so i got it put on yesterday and was happy as can be. that night when we got home i pulled in the garage and when to roll my window up and POP!, Window doesnt move. everyone that owns a ls knows what that means. what a way to ruin such a good day
