Great peice of kit. It was the last thing I needed to do to compliment the I.E. Coldair intake, APR tune, Milltek etc. Sounds monsterous and the turbo is noteably quicker to respond - turbo whine from the downpipe is a nice touch too! One thing, if you buy the I.E DP be sure to check what type of adapter you need for your exhaust and also order an O2 extension adapter - or you may find your engine light comes on - needs to be further away from the DP due to larger diameter and more more air flow.
