so a couple days ago I installed a set of Belltech 2" lowering shackles, and they've been riding just fine I even checked to make sure the bolts where tight and everything checked out.

well today I decided to throw on a cherry bomb muffler cause my wife said my truck is quieter than her Passat, and I don't have money to get much of anything else out here in Hawaii but anyway, We drove the truck a couple miles and it feels weird, Like the back end is floating/wiggling around, but its till has traction when I get above 50 mph it doesn't necessarily get worse the fast you go it just feels slight enough for to feel it but the truck stays straight and everything (Wheels, Shackles, and Exhuast) are still tight.

Anyone know what might be going on?

 

I've always heard that Hawaiian weed was pretty stout though!
