After thinking about getting rid of it for a diseasel boremobile thought f*ck it why not..
Removed all Three cats and replaced with 1 Prodrive sports cat (From STi PPP) and two decat pipes. Already has deresonated centre pipe & panel filter fitted.
This has already made a hell of a difference in spool up and acceleration!
Next steps are uprated fuel pump, intercooler hose kit and Remap.
Advised that this will be good for 270-280BHP (and a sub 5.0 to 60) on standard TD04 turbo :-)
I'm quite pleased with this considering the cost will be less than a grand..
