Strong buzzing sound near engine bay
So i did a 70 - 115 mph run last night and was going 115 for about 10 seconds then i get to a light and accelerate and hear a very very loud buzzing noise evertime i accelerate , at idle there is no noise only on acceleration, any clue what it could be ? Any input would help
Thanks in advance

its probably an exhaust leak.
i have one with my LSJ dp, that and the ******* thing knocks the sway bar.
which is why i need a new ******* downpipe. only 3 days after putting the LSJ on. ugh

Well, i will check today and see if i can find a crack or something, the noise is between a flutter and a buzzing, the noise stays the same speed of the buzzing stays the same but it does get louder. Also I think the probably the exhaust manifold gasket is blown too. My first flex pipe blew at 35k and now again , GOD how cheap does gm make stuff lol. Well anyways i tried to determine whether it was a knock or a buzzing so far i stay with the same thought of the buzzing, also it seems like i am losing lots of pressure in the exhuast because on the passenger side you can hear air.
Thanks for the input so far guys
