I'm going to OBX later today (they are only located 10 minute from where I am) going to pick up some LSD and ITB for Honda's if anyone want to give this exhaust a try pm me I think I can beat ebay price.
OBX have their own manufacturer overseas that is why their product price so low (no middle man)
by looking at the picture I think this exhaust is a Stillen replica
here is a picture of the stillen
and the OBX one
