my gasket on my J's exhaust got a little bent. and i need to get a new one. i can't tell if it is leaking or not. until i get a new one, should i just leave the bent one in or remove it? what could happen if i don't have one on?

 

if it doesn leak.. leave it

 

how do i know if its leaking? is it possible to not have a gasket on and not leak??

 

You can usually hear when you have an exhaust leak and it's not likely to not have a leak without the gasket.

 

what does the leak sound like?

 

An exhaust leak would be obvious, like a loud riced out civic, it would not be a quiet sssshhhhhhh!

Turn on the car and listen close then put your hand all around the gasket without touching it! Do you feel any hot air escaping?
