I think my exhaust might be blowing toward the back. How can i find out where the leak is?

Get underneath and have a look.

I cant get underneath at the mo 'cos my axle stands are under my locost chassis. I had a look with under the car as well as i could but couldn't see anything.
I didnt know if there was some easy way of finding out

Hand over the end of the exhaust to block it off and listen / look for the leak.
