I'm not sure how well stocked your tool box is, and what sort of shop
equipment you have to tackle the exhaust system.

I do know this.

The exhaust shop has a rack, and a oxy-acetylene torch.
And they'll be eating the rust flakes, not you.

For a 100 bucks I wouldn't even think of touching it.

Think of it this way.

You just bought yourself a birthday present.

If you screw it up, your going to pay somebody anyway.

If you don't have the right tools, ship it out.

Why even get started on this miserable job?
