I've had a hole start that would of ended up doing what your would have done!
I would seriously yes consider getting it rewelded
BUT - BEFORE REMOVING IT - Put some nice deep scribes in the alignment, so that you can tell where they should meet
As you will need to clean up the join area to allow it to be refitted when welded up

Depends on the quality of welding and if its by the book or on the side 
My local place i use is £20 minmum for any job
So i've had 2 cracks welded up on mine that pretty much ran around the circumfrance but did split
Ring around and ask
Ring local garages to get a quote
I've always provided it pre-cleaned up so that they can literally just suit up and weld
It also helps provide a decent join

For that price you could probably pick up a 2nd hand manifold for less and fit it yourself.
Small job, easy. Jack, axle stands, PlusGas and a decent socket set is all you'll need.

65 squid for 30min welding is to much, go to another garage or change it yourself

Hell I didnt even use axle stands
I can get the bolts off without jacks/stands
Onlu need the emergency jack to get it from under car once its laying on floor

Yeah im gonna see if i can get it done cheaper and i defo wont be able to fit a manifold myself someone would have to guide me how to do it step by step i can only change tyres might just get it welded if that dont work then i have to replace manifold the manifold it looks rusty and old anyway

Changing the manifold on one of these is possibly the easiest job I have ever done on a car. It could be argued it is easier than changing the passenger side headlight bulbs on one a Punto.
Don’t worry about it looking old and rusty they all do after a couple of days on the car due to the heat from the engine.
Tools needed the emergency jack, 13mm (at least I remember it as 13mm) socket and wrench plus small extension bar for wrench. Open ended spanner to fit the o2 sensors in the manifold. Your chosen release agent such as WD40 of plus gas (whatever works for you). Scraper to clean off old gasket. Torque wrench is good if you have access to one for checking the tightness of the manifold bolts once refitted but you can do it by feel.
Parts, replacement manifold/cat assembly, 2 x nuts for flang bolts on end of manifold, new exhaust gasket (about £3).
Instructions.
Couple of days before spray all bolts with release agent.
1. On the day, disconnect the multiplugs from the o2 sensors.
2. Lie on your back and reach under the car to undo the bolts holding the flange on the manifold to the centre section of the exhaust, these bolts may snap if they do do not panic as the bolts are part of the manifold and will be replaced.
3. Some cars have a support bracket from the exhaust to the clutch housing, mine had rusted away years ago, if present unbolt it.
4. If your heat shield is still present remove all the bolts (8 if i remember correctly) and lift off the heat shield.
5. Start to slacken the eight exhaust manifold securing nuts, 4 above and 4 below (use the extension bar to give you access to the lower bolts) Slacken all of them quarter turn at a time until they are loose or the last few may become really tight.
6. Once all the nuts are off slide the manifold towards you and off the studs and lower it to the ground. You can now jack up one side of the car to give clearance to slide the manifold out.
8. Use your spanner and a soft hammer (or other brute force item) to remove the o2 sensors from the manifold and then fit them to your new manifold.
7. Clean up the front of the engine to remove the old gasket and then slide the new gasket over the studs.
8. Refitting the exhaust is reverse of removal.
Never get under a car that is supported by only a jack, however in this case there should be no need to get under the car whilst it is raised. I also find that attacking old rusty bolts with a soft wire brush before attempting remove them clears the threads and stops them seizing as you undo them.

new manifold 150squid?
you can buy stainless steel manifold for 130 squid
it takes 54 mins according to autodata to change manifold = 100 squid in labor?

Slight problem is its a DECAT
Decat = MOT failure
Unless OP fits a New cat in under the car, and thats just more money!!
Also to weld it up properly - it'd probably be easier off the car too!
If the heat shields already rotted off - i'd put a 30min to change on it

Problem is the cat has to be present for the car to pass an MOT.
How about this as an alternative solution.

You might need to trim half an inch off the end of the damaged section of pipe with a hack saw but that wont take long.
New cat with manifold can be had from Eurocarparts for £102 or £76 from Ebay so £150 seems a little steep. Given the garage are buying trade they appear to be doubling the cost they will pay for the part.

go to scrappy find old exaust in pile with same flange but slightly bigger bore pipe. cut it off with about 3 inches of pipe, cut 2 slits in pipe either side, slide it over manifold pipe clamp on with U clamp use rtv sealant as new gasket.

heard that people put on cat just for mot and then they remove it, supposedly it lowers their fuel consumption and adds power, dunno if anyone tried thaat on punto
