Welcome Mo, well if u r used to the power already then do some mods but get used to the car first

But if you do want to waste money in these hard times here we go.

look on group buys for a break up grade as with great power comes great stopping. sorry couldnt help myself breaks (godspeed)
look in market place for an sti top mount and remove the center cat in the exhaust but keep the 200 cel sports cat for mot unless u have a mot friend then get a 3"turbo back system £250-400.
cosworth panel filter, 550 injectors and a good mapper £250-600. look for JGM, FB TUNNING, DUNX OR BOB dont no his surname
hope this helps

Not sure if we at talking about the same thing mate its my understanding the ppp kit on the wrx consisted off amongst other things a decat midpipe,yes I agrea a cat in both the up and downpipes but again deffinatly a decat midpipe.

When you say centre cat what cat are you talking about ? ?

You must change the up-pipe to a wrapped Harvey Smith slip jointed hybrid one at less than £150 (gains a few ponies but the increase in throttle feel and lower spool up = a better car to drive)

Then sportscat downpipe (see Cobrasport group buy) and straight through mid in 2.5" mating to the PPP backbox or swap b/box if you want louder.

Change the panel filter.

Lastly Ecutek remap.



Personally wouldn't change anything else...

You'll see around 285 bhp and similar torque and it will be super reliable.


Changing the up + down pipes make the most difference.

Replacing all the exhaust with 3" will gain very little i.e. about 2-4bhp.


I did the above on a 2002 wrx and it went very well indeed

If you intend changing the up pipe, adding a VF35 and STI pinks at the same time should see around 310bhp. If you opt for the STI top mounts, reckon a few more bhp. And so it goes on and on.
Brake upgrade first I'd suggest. The standard brakes are at their limit with PPP at 260ish bhp.
