Im looking into upgrading my exhaust with a flowmaster 70 and change the y pipe, but I heard things about exhaust flutter, but dont know what it is can someone explain it to me, its a V10. thanks in advance -John

 

It was supposed to be fixed around 00-01. The 02 up, had some upgraded pipe already. My 02 still has a bit of the flutter sound under my feet. There is a lot of positive input on the y-pipe mod, it's on my list of mods to do too.
