exhaust sounds louder than usual, power loss, smell burning

[gardener87]

exhaust sounds louder than it usually does and when starting up, first few revs seem to not go very smooth as if there may be a hole or something and its escaping before it goes the whole way through the exhaust
van started to kangeroo jump a little as if u have it in too higher gear which i didn't
so getting a bit of power loss and can seem to smell a bit of burning
could this be my cat blocked or something??
or could it be my clutch on its way out?? ( the burning smell does not smell like burning clutch as i know what that smells like )  the pedal has quite a bit of play in it before it bites

Get the torch out & have a good look at everything.

if i cant make out any holes, can u feel the air getting out when the van is on, could i try giving it a coat of washing up liquid wont it blow out bubbles??
as its just me trying to fix it wont have no one to press the throttle

Pull the choke out to get the revs up.
 Or a brick on the throttle pedal.

get someone to push and hold a rag over end of exhaust  and you will here any leaks quite easily as pressure builds up
