Well i have original muffler on my 2000 nissan maxima with the dual pipe on one side, and one pipe seems to be clogged. my exhaust just barely comes out of the left side i think but shoots out of the right side? Anybody know why that is?

 

How exactly did you determine this, and what is your problem?

 

Normal, the muffler opens up both pipes only in the upper rpm's

 

i started my car and walked around back to see it? And the problem is i thought it was clogged but the question got answered now.
