I drive a 1.2 TSI and although i'm not after a performance increase as such, I'm after a improved engine note, specially in the higher revs. Sometimes at lower revs the engine can sound a bit raspy. I read the VW watercooled forums and motor-talk.de forums and a lot of members seem to have this fitted to their 77TSI's. Basically i'm just seeking opinions on whether it'd be a good purchase or whether it would be a waste of money.
Cheers in advance
