MORE POWER!!

Hi Richard, I would go exhaust+filter followed by a remap. Not really any budget options, keep an eye on the classifieds and you may be able to get a secondhand exhaust. If your going for all new then approx £400 for exhaust and filter. The remap will be around £650 but it is, in my opinion, the best option.

IMO I would go for a whiteline handling kit (Anti-Roll Bars, Drop Links and Anti-Lift kit) and geometry adjustment. Worth more than a remap in my view, even though it is not a power enhancer.

ARB is Anti Roll bar I changed the rear ARB on my STi and honestly didn't notice any difference and I am not a numpty when it comes to cars.
Power wise:- panel filter, as the original air box is the best there is up to 360+ hp.
Decat downpipe and up pipe if yours has one. That will make it breathe much better.
Then eventually, a Tek 3 remap, but in the meantime the panel filter and decat will be Ok on a UK car, on a UK map.
Handling wise: White line anti lift kit is a good place to start, then probably a full geometry set up with 2 camber bolts from Eibach to be able to set the camber properly. Then see how it feels - it is perfectly possible to go too far and have something great, when in fact good would have been sufficient. Especially so, if trying to stick within a budget
Call if I can help or advise more.

Thanks. i have been looking at a down pipe on ebay item number 270298891545 . But not sure weather the car will need remapping cos of the lambda sensors? It's a u.k car but do i still go for a de-cat or sports-cat?

If you are concerned about dolphins and trees then sports cat. if you want to go fast - decat.
Your choice. The orginal map will cope with the decat or in fact either choice.

It'll be fine on the original map. It WILL be a better car for a remap, but in this instance, it is not necessary to protect the engine, like you would need to do an a JDM car.

Thanks for the info, you have prob saved my engine and ecu. ill take a look at your site. Do they have sensor sockets on your down pipe? Is a K N panel filter a good replacement or pipercross?

if you want more power get these...
3" turbo back decat exhaust and up pipe, heat wrap your downpipe
cold air intake
upgraded tmic
exhaust manifold heat wrapped
ecutek remap
and you will have over 300+ bhp and 300+ ft/lb torque

What about on a prodrive map on an 03 wrx could I fit an up-pipe and a ppp sportscat down pipe and be safe on the map until I get some more money together to go for a remap. I presume just either a resister mod or cel delete will stop the light after removal of the up pipe cat, If I go cel delete anyone know which one to delete as I have a tatrix cable and would feel better doing it this way.

Your idea should still be OK as the map will cope with the upgrade. Like I said before it won't be perfect, but it won't be far enough off the beaten track to cause problem in the short term.

Can you go too big then? I was told the less restriction the better...
Partly why I'm considering the outlay for the APS 3.5" system...

An amount of controlled back pressure is necessary to make it all work, until you get to big power, then as open as possible just to shift large amounts of air / gas.

You NEED a 3 inch system from 380 hp up - below that you will get a better [ more useable / driveable ] result from a 3 inch open throat decat that necks down to 2.5 inch at the mid point join and then a 2.5 inch system all the way through to the back box.
