wierd sound?...

Was going up to wendy's tonight, went to pass this honda crap, but as i floored it i heard a wierd airy sound comign from the back of my car, never heard it before. On my street coming home i wanted to double check, floored it again and same airy sound. Any ideas as to what this could be/anything wrong?

please describe "airy" for the non "fairy" camaro owners on the forum ;)

single exhaust?...v6?..ive heard some do that
with the factory single outlet muffler.

airy like... the sound of ... an air leak i guess? (remembering). And yea v6 stock exhaust, i was lookin at getting a magnaflow soon anyways (may get that package on ebay for the catback + high flow cat, same price as i've found the catback so i fugre why not get the cat as well). Thanks.

my mom has a ford explorer that sounds like
its spewing air when she gives it the gas.
and yeah, go for the cat and exhaust i
need to get all new exhaust put
under my 94 z28. its all to hell.
the muffler fell off saturday night,
and there rust holes all in the pipe
coming back from the cat.
