Rattling sound around 6-6.5k RPMs under WOT
Hi guys!
I've noticed since I got my 8 when I punch it to get to redline (gotta flush that carbon out) around the 6-6.5k RPMs there is like a tin-like rattling sound but it goes away after passing that range.
Any ideas? I've done some searching on here and some threads mentioned it was a normal noise and/or it was a catalytic issue? I'm pretty sure my cat is going to crap very soon.
Help is appreciated
