All the PPCGB stuff is one piece, no seperate difussers, same as most of the ones on the bay. The side Zorst exit one doesn't come with a tow eye IIRC. There have been some SHOCKING phots on here over the years of these and the crap fitment, some are out by 1 to 2 cm either side, other are ok, you pays your money.
Ive never had a copy so can't comment on quality or fitment but for £100 is no biggy if it's sh*t, it's worth a punt.
OEM one (obviously the best and bound to fit, look at mine) will be £350 ish from VW plus paint on top so might be a bit much for some.
