I figured it out, I have an exhaust leak/springs rattling on the axle back connection. I got rid of the springs and bolted straight through with big bolts and lockwashers on the test pipe it helped a little bit. I'm going to do the same on the back to get a good seal. My muffler hangar also broke, it must have happened when I had to push the exhaust back about an 1/2 inch to accomadate the slightly longer test pipe, shitty generic muffler.
