I ordered the dual tip flowmaster american thunder series a while back. Complete bolt on application and installed it myself.
The issue I am having is that it is knocking on my leaf springs on both sides around the hangers. On the passenger (original exhaust output side) it is the bolt for the tip knocking on the leaf spring. On the driver side it is the aftermarket hangar that is knocking on the leaf spring.
Just wondering if anyone else is having or has had this issue. I have tried to correct it by adjust the placement of everything but no luck.
I think my only option now is to have the pipes cut a bit so the areas wont come in contact with the springs.
