Need help please......

I have an early hawkeye (dec 05) STI with PPP

I want a full decat

What fapping pipes do I need

I think .... I need a decat downpipe and decat uppipe can anyone confirm that for me please...

I think the PPP on the 2.5ltr was just removing the cat on the centre pipe rather than replacing with sports cats ?!??

Cheers in advance this has been doing my bloody head in!

Got an itch

Get a decat down pipe and keep your PPP decat rear centre, no uppipe decat required as it's already done

the upipes done ??!?!?

So it has just one cat on it at the mo then?

Thought they came with 3 how can just one cope with the emissions reduction?

Correct, same way it does on the MY05 Sports Cat PPP

On my Spec D I have a H&S Sports Cat, thats it, all else is just straight through pipe.

WRX has 3 cats inc the one in the uppipe
STi has 2 cats the one the PPP removes and the biggy in the DP

275ATW is a nice safe figure for what you've currently got tbh

I agree! Just looking at the next stage

like to go to about 375bhp so 315ish atw eventually as I don't want to have to change all of the internals!

You wont get much more with a decat if you're already at 275 ATW (is that Ecutek delta dash or from the Zen rolling road BTW?)

Next step is a bigger turbo, but not too big if keeping the bottom end std.

zens RR.

Bigger turbo (as you said not oo big though) uprated top mout IC or FMIC .... then that'll do ..... until I get bored and then onto internals LOL
