Seems like an improvement, pulls better, but felt better after the milltek downpipe anyway.
The twintake making more noise, got more chatter, so must have upped the boost a bit, will check on vcds next week when I have some time what changes it has made. Seems like its worth the £50
I must also note, the resonated milltek is very quiet, hardly makes any difference to standard apart from high revs and when the car is under load
