General Exhaust Noise ?

[mat22]

Hi,

Since yesterday it sounds like my exhaust is blowing.

Thing is today i took a look at the full exhaust and see no holes, gaps etc. It sounds exactly like it is blowing yet as i said cannot find any corrison, holes etc on exhaust. It never sounded like this before. I also checked and tried to move exhaust and again it is tight and not loose or anything.

I here it more going up gradients/hills which i would expect.

Anyone have any ideas what it maybe or anything i could check?

Thanks,
Mathew

have you tried checking the exhaust manifold? check for blown gaskets and any sign of soot or black/burned crap. also see if its more noticeable when hot or cold,

i noticed this to on my 55 plate dynamic it even was re adjusted by the garage for the mot because they said it was blowing a bit at the joint (bloody speed bumps) but it still sounds a bit blowy round the back end , i will take the advice about the manifold and check mine as soon as poss

If it's at the manifold end then the sound will go from something like an old beetle to a tractor.
