do you have poly motor mounts as well if so there's some of your noise and make sure the bolt that goes thur the cross member did not back out... i had to put two bolts on there to make sure it did not back off

Yea when I first started it and now I drove it now its kinda of a tink tink noise I think when the stock broke it looked like it may have bent the exhaust mount behind the cat but wat was the first sound almost like a hum?

Very common for the poly mount to transmitt drivetrain/road noises..If you go to dealer purchase theLs1 mount its very strong compared to the Lt1 style 3 years on my car m6 at that.
