Hey guys, I've got an irritating vibrating type sound when i'm doing about 80-85mph and it sounds like its coming from the mid-back area. There's 2 types of sound, there's a clangy metal flapping sound and there's this (vooooooooommmmmmmmmmmmmm) type vibrating sound, but i think they're both caused by the heatshield which is situated in the middle of the car. The vibrating sound is the one i get at high speeds, and at low speeds it becomes a more distinct clapping metal-to-metal sound. Now one of the mounts, when we were removing the exhaust/propshaft a while back broke because of excess rust, and now i dont know how to mount that part of the heatshield back onto the car. I was thinking to weld, but what if i need to remove it again? Anyone got any suggestions?
