I have got a 2005 wrx with PPP otherwise standard and would like a bit more power.Any suggestions.Hear a lot of talk about decatted uppipes and downpipes,i understand 2005 wrx has cats in both..Will car pass mot with either removed.When PPP is fitted is cat retained in centre section?What benefits from custom tuning prodrive ECU?Any thoughts or advice on this subject much appreciated

 

i have a 05 wrx ppp and decatted it then got a remap made a huge difference also passed MOT no problem with the decat.

Also have changed induction kit to cold air feed k&n

 

Did you decat both uppipe and downpipe? very tempted to go same route with my PPP.

 

decatted uppipe and downpipe.
k&n panel filter
sports 100 cel cat
results - 280 bhp

td05 turbo
550 injectors
result now running 330bhp with 332lb ft

 

forget to mention mine is a 2005 wrx with PPP. it was running 257bhp, not the 265 PPP claim.

 

JGM, Simon mapped car both times after the mods.

 

I went for a Miltek 3" decatted system, Walbro fuel pump with an Ecutek remap. Massive difference over the PPP. Have you sorted brakes and suspension?

 

ive a subaru impreza wrx turbo just wanted to find out something do u need to remap ur car when u decat it ,ive got a powerflow exauhst system from the cat bk .wanted more power and noise

 

passed mot with cats removed ?? wheres your mot man lol

 

On a newage you will need to but you will gain from extra power, torque and fuel economy too. Some nice noises can be added too if you like that.

 

ok thanks any idea how much it cost and whos best to do it as im up in aberdeenshire

 

cheers for the input.How much did that setup cost and who did the work?Did you get much power increase or just better to drive?I have fitted Whiteline rear ARB and drop links probably gonna fit front ARB and need new front pads so gonna go for DS2500.

 

cheers for the input.How much did that setup cost and who did the work?Does it still pass mot?

 

Speak to Grant at AWD in Perth or go direct to Andy Forrest. AWD use Andy F so might save a few quid going direct. He doespost on here as Andy F

 

only removed one cat think thats why went through MOT no problem
do think you have to have a remap to see real benefits after the cat removal
