Will it need a remap ?
Just changed the rear peashooter type exhaust on my WRX for a Prodrive one . I was told also that I could if I wanted remove the centre section for a straight through pipe ?
My question is , if I was to get the centre pipe changed for a straight through section , would the car HAVE to be remapped ?
The cost of 500 notes for an initial remap I cannot afford at the moment ... so what gains if any would just the pipe make ... just more noise ? Lack of power ?

I would buy a wide band lambda and have it in your car. I doubt just a back box will lean your car off significantly on its own, especially if you are retaining the cats. Also monitor boost, an increase in boost will be a clue that the ve has been improved.
