Hey,

ever since i got my car I've noticed that there's a metal on metal sort've sound when I rev the car in neutral. When I'm driving the noise is completely gone. I am confused about this and I need some help!

Also my cat smells horribly, I'm pretty sure it's about to die on me. I had the car stall recently and maybe the cat's clogged?
I am also interested into getting a straight pipe instead of the cat


Here's a video of what it sounds like

Thanks(:

 

Check the heatshields under the car. They might be loose.

 

^^ Very right!
Sounds like a loose shield, or bracket of sorts

 

You should put bigger Coat of arms so everybody can see it.

 

See what?
