Exhaust Shop Recommendation

Hi,

The hangers on my exhaust seem to be rotting off throughout the system I've had them welded back on but it doesn't seem to be a fix that lasts.

The car is my drive to work/family estate and main dealer cost is a fortune for a replacement and there are no aftermarket ones available. That got me thinking would a exhaust fabricators be able to sort me cat back system. Would want similar to standard noise and looks.....

Any recommendations in the North Yorks area? I've always try to stay away from these places due to fears or dubious quality/fit and nasty noise.... Am I right or wrong?

Thanks in advance!
