The Wire Bandage method
Tools/parts needed:

An old coke or beer can.

Tin snips 

a pair of pliers

Plenty of J.B.weld or chemical metal., I have tried both of these prodects and neither caught fire anything drastic, so I can recommend them. 

1-2 mm wire, make sure you have plenty. 5m is usualy enough, and it's always wise to keep in reserve.

1. Clean the part of the affected part of the exhaust, especially edges of the hole. Use a very coarse sand paper or wet & dry. This is for the chemical metal or J.B. weld grip to.
2. Cut a piece from an old can (I usually use an old tin, but any soft drink will do the job just as well) to fit over the hole and an overlap of about 7mm. 
3. Mix the enough chemical metal to fill the hole and to cover the outside of the plate, and a bit more.
4. fill the hole, (if possible), and smear some of the chemical metal or J.B. weld the outside of the hole. make sure that this area is bigger than the plate you just made.
5. Place the plate you just made over the hole & chemical metal or J.B. weld you smeared on the pipe.
6  Mix more chemical metal or J.B. weld, enough to cover the plate and the edges and a good overlap.
7. cover the plate with chemical metal or J.B. weld making all the edges of the plate are covered, old again a good overlap
8. Take some thin wire (1mm core is good enough which you can get from any good hardware shop). Bend the end of the wire 90º, then hold it onto place onto the pipe, about 10mm away, from the plate.
9. Wrap the wire tightly around the pipe, leave plenty of gap as this first wrap is just to hold the plate into place before the main wrap.
10) Wrap the wire very tightly together, as tightly to the pipe. Start about 10mm before the edge of the plate, and end about 10mm end of the plate. If you find some bits of wire aren't tightened enough, use a pair of pliers, just grip the loose wire and twist to tweak it.
11) Mix plenty more chemical metal or J.B. weld, and smear it into the wires.
12) Leave to set before riding.
Here is one I did bofore, It's done about 1,200 since it was done, and still is airtight
