I was hoping to save $12,300 (Boston Lambo quote) on the race exhaust, but still might go with it. We just got our first snowfall and massive salt dump of the season, so the party's over, for a while anyway...
Yikes that's expensive! Last week I installed Fabspeed Supersport Valved X-Pipe for less than half that. Had my friend who has a shop near Boston Lambo install it and he took better care of car than they would have. Don't let Lambo scare you about losing warranty, we have the Magnuson–Moss Warranty Act that keeps them from doing that. If you want I could hook you up with him







Glad to get the stock monstrosity off
