do you have to keep the upper and lower covers for your cat. like the sheet metal covers.
thanks.

 

the heat shields of my exhasut all fell over (before i got catback) and i was just fine. The one under your gas tank is a good idea, but the ones towards the front by the cat i think you can take off without worry.

 

well if you mean just the cover around the cat converter... id ask WHY you wana remove it? its jsut a extra heat cover and shield from stuff that gets kicked up from damaging it.... id keep it thier... its thier for a reason...
