Hey guys,

So I just recently installed my Borla S-type exhaust on my mustang. However, I have noticed that in the mornings when starting it up, it has a slight rattle.

I have heard from some members that they drained water from the exhaust by drilling a hole in them?

We did recently have a rainstorm about a week ago and just wondered if that could be the reason for the rattle.

Does anyone know how we can check to be sure.

I don't want to start drilling holes in my exhaust if I don't need to.

Thanks again and let us know if you had a similar problem with your exhaust.
