manifold or downpipe gaskets may be leaking gases or worse, cracked manifold
You need to specify type of noise. I would assume you have problems with exhaust. If you do, you will have fix it or replace it.
The most likely cause is an exhaust leak or a cracked exhaust manifold. While it is also possible that there is a problem with the Camry's catalytic converter, check to see if there are any leaks from the exhaust or any problems with the muffler first.
What is the roaring noise from a 1999 Toyota Camry XLE at speeds over 35 ? Sounds like it is coming from the rear.
have you checked to see if there is any broken bolt on the manifold, or worped manifold, burnt manifold gasket
State your noise.
A bad exhaust manifold gasket could do that.
squeeking from exhaust manifold is caused by a leak allowing exhaust gas to leak. it will only get worse as time goes on unless it is fixed
did you check the fuses?
nope - none in mine
This noise is caused by the exhaust manifold gasket being perforated adjacent to the flange of the branch of number one cylinder, the noise is being created by high pressure/back pressure in the exhaust manifold escaping betyween the exhaust manifold and the cylindert head- Owen Diesel
That is lifter noise, they probably need adjusting
Loud exhaust noise from the front end is usually caused by one of several problems. The exhaust manifold gasket could be blown, the doughnut gasket could be bad, or there could be a crack in the exhaust itself.
