ok so i've got a SI/DO flowmaster with custom bent tailpipes, they are squeaking where they are connected to the muffler, i tightened everything, didn't work, loosened them a bit and it helped for about a week, and its back again, they squeak with engine vibrations, bumps in the road, and when i shut the door, frankly it driving me nuts, is there anyway to stop it?

 

weld them homie

 

what ^ said. weld the **** out of it lol with a wire welderbut dont run a continuous bead.. use short tacks
