Hello everyone, im looking to see if anyone has come across a problem with the Ark straight test pipes for the 3.8 GDI. I just got mine installed over the weekend and while im driving it it sounds as if two pieces of metal are vibrating on eachother after i put them on. Nothing is making contact with the heat shields or anything, the "rasp" is honestly hideous and embarrassing. Ive looked all over these forums and cant seem to find a solution. If anyone has some tips for fixing this it would be greatly appreciated!
