Can you weld my exhaust for me
 

Ok, so when I bought my car, my cat was cut off from my stock exhaust. There is a gap about 2 ft on my exhaust and a pipe was put on there so I can actually run the car without it being loud. It's leaking a bit and I dont like it. Can you weld a pipe on there for me. About how much would it cost for you to weld on a pipe.
