Do I need a re map or not?
Alright guys,new here so go easy!Just bought myself my first scoob a 2010 wrx - s edition,pick it up on Wednesday!Whilst out on the test drive I noticed there wasn't much noise/burble coming from the exhaust,I would like to maybe change the back box,change the full system or de cat it!any other ideas would be welcomed!ive been reading a few bits and pieces and some are saying a re map is essential and others are saying it dosent matter just looking for some opinions,from my understanding though the wrx s has already been fiddled with by pro drive so is it a good idea to do it again?!Also would I have to remap if I fitted a dump valve and K and N!Thanks for your time any help appreciated 👍

Welcome any pictures?
To start off for a back box changed i wouldn't bother personally doing a remap. But if your going to decat the exhaust i would recommend it.
Although saying that there loads of impreza's running, decat, dump valves, induction kits, full exhaust changes with no remaps at all. Problems you will find with that is your car over fuelling etc and i wouldn't recommend this, essentially not with a 2010 plate car.
So in answer to your question yes, get it remapped if your doing anything more than back box and changing your filter. I've changed my full exhaust system and have a dump valve fitted, but have not had it remapped as yet, but will be done in next few months. And most likey will be removing my dump valve as it causes over fuelling.
Most people on this site hate dump valves, if your referring to vent to atmosphere ones, due to some thinking they sound chavy and others saying they cause over fuelling and bore wash so be aware. Hope this has answered your question?

If you want the subaru burble you will need to change the headers to unequal length headers. Yours will have equal length which wont burble no matter which system you put on it.

if you have the budget go for a cat back system and you should unleash a good bit of sound from the exhaust. Generally the more you pay the better it will sound, the backbox is massive on the hatchbacks so eats up a lot of the sound on it's own but the small resonator in the centre section also does a good job of killing noise.
