For my 95 civic/b18c with a full exhaust the offset left would not line up. Go for offset center. Yours could be different but I say play it safe and go offset center. My muffler guy also noted the universal muffler is bigger than the system muffler and comes dangerously close to the suspension.

 

Cool story bro

 

your muffler guy needs to get better at his job.
the universal is also straight through while the system isn't.
theres more then one size btw.

 

I don't understand a damm thing.

 

OMG, the OP posts this without even realizing that the WS muffler can be ordered in different designs, including both centered and off center outlets

156-A013 60MM. INLET OFFSET-LEFT

156-A012 60MM. INLET OFFSET-RIGHT
