Hey guys, I just purchased a 2010 Nismo and have noticed at first start-up a exhaust noise/leak for about a minute and then it will go away. I can't feel any leaks, but it's hard to get your hands in there. Has anybody seen or heard about an exhaust leak (or relation to) The car has only 5K and I know it is under warranty just want to see if anyone else has this condition? Thanks
