New guy to the site, and as others have mentioned PPP is recommended a lot on here, being a Subaru approved performance mod which doesn't invalidate the warranty....
So i looked into it, is it available in Finland, it is, albeit only 1 place and it's halfway up the country. 2ndly, everything in finland is easily more expensive than in UK. Read in 1 post that it was around the £2000 mark = 3000€, so for sure it's more than that here. And the final nail in the coffin, contacted the Subaru dealership to see if they knew whether PPP was available in Finland. It is but it voids your warranty.
