hey guys, sorry for posting another thread you have all helped me learn a lot already. the problem im trying to correct now is a clicking noise when i push on the gas. it sounds like it is coming from my exhaust and is pretty annoying. i have checked the pipe and muffler for any cracks or holes but i dont see any. does anyone know what this could possibly be? or where to start looking to find the problem? it doesnt change how the truck drives at all, it just sounds annoying and takes away from the sound of the truck. thanks a ton!
