I just discovered that my 240SX has two mufflers, one a little after the cat and then the one at the end. The one in the middle needs to be replaced since the entire area around the outlet is missing, which caused quite an increase in noise and emissions.

My question are as follows: Is there supposed to be a muffler there? Would replacing it with piping cause a loss of backpressure or anything like that?
