exhaust noises..., at least i think Options

i have noticed for a while that my when i am at full trottle that aroudn 3-4 grand i hear a wistleing noise which seams to come from the back of my car. i can hear it better when the back seats are down really well. my dad told me to put a rag over the exhaust and see if it made any funny noises like it had a leak or something but it didn't. so he thinks the only thing it could be is possibly the catalitic converter. i thought i would just see what u guys though.

i had the same problam after about a month with my new exhaust....it was like a rattling type of sound...i eventually realized that it was the the heat shield thats over the muffler..i i jsut hammered it out f the way and the noise stopped..

the thing is its not a rattleing noise it is a high pitched wistle. plus mine is the stock exhaust right now.

well the cat is not in the back of the car, so i dunno about that guess.

my guess would be a leak as well, it could be on the piping right before it goes over the rear right axle.

my guess would be jack up the car and see if it's there...maybe you bottomed out hard or hit something

When you say full throttle it leads me to think that there could be a leak in your fuel lines. Just a thought. You dont smell any gas when you exit the car do you? Just check all of the piping, fittings, and lines underneath the car.

no i have never smelt any gas or any fumes around the car...im gonna check it out this weekend and inspect it more closely this time.

it isn't only at full throtle, you can just hear it the best at full.
