You need a V6 4motion rear valance, ?40 from the dealers or VAGparts or Awesome Gti.[H]just 2 pipes on the same side, but I dont want to be doing any cutting, cos I think the diy jobs look crap especially if i do it!
You'd certainly hear it though, and I like the idea of that, stealth in looks but nice sound when you rev it  There is also the benefit of corrosion resistance. Even if there was absolutely no power gain (Milltek did quote me some approximate figures even though I told them I have a 1.6 NA) I'd personally still go with hidden tips.Just out of interest what model mk4 you putting this exhaust onto?
If its a N/A golf then you won't see any power gains and the only reason to get it would be for looks. So the discreet back box would be pointless.
Anyway you should decide whether your are buying it for looks or power increase as ?40 for the rear valance isn't alot extra to spend if you really want to see the exhaust
Thats also the case for the 1.8T, if you want a performance increase then its a larger downpipe and free flowing cat / decat.If its a N/A golf then you won't see any power gains and the only reason to get it would be for looks.
