if i replace the centre resonator and 2nd cat on my wrx blobeye will engine check light come on? im only after a it more noise low down as its ok at higher revs![prodrive back box]. or am i better off replacing downpipe/cat? or just resonator? a bit more power would be nice too but just wana here the boxer a bit more!cheers

 

its touch and go really,

if it does come on Subaru Impreza Ecu Mapping can turn it off for about £30

 

cheers for that,certainly seems an affordable option. i'll be giving em a call soon!

 

Just followed that link and it says its £25

 

yes and im interested in their other services as i dont fancy paying 600 notes for remap after fitting green filter and decat!

 

On that website they say it will cost £125 for the map (stage 2). I thought generic maps where a big no no for imprezas

 

The PPP is a generic map.

There is never a substute for bespoke map. but it bridges the gap between the standard and full blown.

As long as its checked out before you leave (wideband and det cans) its fine.
