Re: Exhaust Sensors
it's probably making a funny sound because the exhaust is leaking out, so all you need to do is plug up that hole in the cat and leave the tube dangling, or remove it altogether like i did. it's hard to say under the mud, but i think somebody welded that hole shut on my cat before i got the truck, but you could plug it up with pretty much anything as long as it can stand the heat. i saw some sort of high-temp exhaust repair compound at AutoZone that says it will close up to a 1/4" gap, so if you want to leave the tube on there, you might try that stuff in addition to the clamps.
