Exhaust problem

[MatthewR]

The exhaust was removed today to fit a new one, there was a problem with the new exhaust so the old one got put back on.

problem is, the exhaust sounds really loud. Is it likely to not have been tightened up properly?

If so will it be ok until Monday? The garage isn't open now until Monday and I only have there adult jack so don't really want to go under the car with that and I don't want to pay another company to check / tighten it up when It carve done on Monday.

Sounds likely to be blowing , check front and back of the cat as the most likely position

What can be done if it is blowing?
