Broken exhaust pipe, how to fix?

[HCJtractor]

My M 6800 has the exhaust pipe that exists through the hood. As we use this in the woods a lot, we often catch the pipe on low hanging limbs and vines and bend it back. I have even bent the hood a little where it comes out. I usually just push it back in place. Today i noticed the pipe from the muffler to the vertical exhaust (where it has been bending) has two cracks and perforations. This is under the hood. So i am sure I am getting some exhaust gas leaking under the hood. It has probably been this way for a while, and I see no damage or evidence of a problem. When it is running, I still feel good exhaust pressure coming out the regular pipe.

My question is this really a problem? Will it hurt the engine compartment? I need to have it repaired, and I guess any muffler shop could do this, but it would take some welding, as the pipe is welded to the muffler. Is there a cheap quick fix? Is there any heat resistant tape that will hold up to wrap around the perforations? I hate to put much money into new pipes, as I am sure I will bend it again. The problem is the design places the exhaust in a very vulnerable position, as it is the first thing to catch a low hanging limb.

Good chance the crack will continue than fan will blow fumes towards you,also after while you may notice build up wires etc.

If repair made,I would add collar over damage area make it tad stronger.

Many tractors don't have their exhaust sticking up,they have them coming down,mine comes off motor and goes down towards front,so,maybe instead of just fixing it like it was,this would be a good time as any,to eliminate your problem and move it.
