All blob WRX I think.
I base that on just having a decat put on Mrs Stig's 2005 PPP wagon to mitigate the risk of the cat breaking up and ruining the freshly rebuilt turbo.
As it was all apart and one of the studs/bolts was a blighter and snapped it seemed a bit of an obvious step to take... trouble is, now it spools fractionally quicker it feels a bit nippier than the Forester!
