Finally got round to getting my decat pipe fitted yesterday after the MOT, so I've got 12 months before I need to worry about the emissions. The car is now considerably louder. Rather unpleasantly so on the motorway, if I'm honest. But at low revs and on overrun it sounds awesome. Doesn't really feel any quicker but seems to be a tad more responsive (boost climbs quicker on the gauge) but only to the same peak level and it does feel a bit freer higher up in the revs. It seemed to strangle after about 5500rpm before. Overall, for 40 quid 2nd hand and a couple of quid for wrap, a worthwhile mod. Next on the agenda, chip swap and FMIC and a rolling road session.
