On the passenger side of my stock 1994 the front plate of the muffler is recessed like 4 inches and there is an exhaust hole pointing towards the front of the car. It looks wrong but also looks stock. It smokes out of it when warming up a bit and the driver side exhaust tip feels much stronger than the passenger one. Is the hole normal? I figure it's like an muffler bypass for wot or something? Can't find anything on it online.
