I have a quarter-sized hole in the back of my REMUS muffler and would like to get it patched...yes I have taken it to a few shops and it can be patched, but they wanted $80-$100, so if you no someone who can do some simple welding and wants to make some $$$ let me know.

Call Whiteys in Chantilly. Dude's an awsome welder and since it's a simple fix he'll probably do it for relatively cheap.
