I'm looking to open up the exhaust with a new muffler on a 1998 Civic DX...any recommendations as to manufacturers and/or suppliers?

 

I recommend just getting a full catback and keeping your stock one in case you ever want to sell your car. Anyway, I like Greddy or Apexi. I would just buy a used catback if I were you because they usually aren't too much and you don't have to have the muffler welded onto your stock piping. Also, a full catback performs better than a muffler with stock piping.

 

if you dont wanna spend too much money just get the es oval muffler.

 

es oval

or ITR exhaust, you just need to have it welded at the hangers or place them somewhere else to fit or it will be wobbly
