He has the 2.4L 4 door sedan, He's looking for some performance parts, I tried using the search but it keeps crashing.

Right now he wants to buy a 60 series flowmaster and they come in 2 and 2.25" sizes, What size exhaust is the stock accord?

Also do you know if he needs center/center or center/offset? Im guessing double center but I can crawl under the car and look before we purchase I just need to know the size.

Also he wants CAI and other stuff like that.

TIA
