I have a hole in my muffler a little bigger than a golf ball and I want to do some type of cheap repair just to keep it on the road for a few months until I replace the muffler. I do have some muffler putty,a couple different kinds. Email me with your experience, what you think the best thing to do to repair the hole is and how much you will charge to take care of it. Would like to get this done as soon as possible. Thanks for looking and I look forward to hearing from
