I am suppose to be getting the new injen exhaust installed, but injen said there was a black canister of some kind under the car that is getting in the way of the exhaust. It was probably disaligned in a previous accident. I am going to have a body shop look at it, but I was just wondering what it is.

It is the black canister right next to the exhaust.

 

IIRC, it is part of the emissions system related to the gas filler. Some of the JDM exhausts don't work on our cars because in Japan they don't have that piece.

Hopefully it would be easy to realign it. INJEN was previously doing test fittings on my car and after the accident, it didn't fit anymore.
