I was windering if anyone can give me heads up to whats going on. I installed my invidia catback yesterday took it for a test drive and i was well impressed with the gains and overall feel. The only thing that did puy me off was the sound which is a bit tad loud for my liking so i decided to put the silencer on it sounded much better. But the problem is when i really open the baby up, i get this nasty rattling noise. Has anyone else had this problem? any help on this would be well appreciated.

Mods are Invidia turbo back, cobb stage 2

hey i went wit invidia dp and skunk 2 megapower cat back.. when i put my dp on it did made that sound cus the dp didn't line up wit the trans. to be bolted up. and i made the nasty rattling sound when i turn or go wot. At the end of your dp you should have another bracket to be bolted up... wut i did was have one of my friend push the dp to the left so it would not touch the black metal piece that is next to the dp. once the dp is pushed away bolt the bottom bracket as tight as you can.. that should fix the problem.. pm me if you have any question.. ill email you the pic if your confuse wit the whole thing.
