drive it for a few days, climb underneath the car with a treble light and look for black soot around the joints.

Thats the easiest and most obvious way i can think of.

Hope that helps

Close your legs! :) j/k

In the trunk where the scissor jack is stored on both sides, you will notice an opening. And in that opening is the source of your troubles...

my source of trouble? i dont understand man......care to enlighten me more or how i could fix it?........or anyway to detect the leak

[DRFT]

im guessing the hoels in your spare tire well? the holes that let water out, if waterever got into the well?

and the opening where the scissor jack, as he stated.

also a good way to check for leaks would be to use water. If the water bubbles then you have a leak. Try when it is cold so you dont pour cold water on hot exhaust system and crack it or warp.

if there is a leak...anyway i could fix it?......like any sealant i should get to seal it?

weld it. or also check your exhaust gaskets too.
