I used a dubpower one with their decat in my mk5/mk2 and have had no quality issues so far, as said very well made and would also recommend their decat.
Never seen a used one for sale. I too went for their manifold and decat when doing my mk5 R32/mk2 conversion last summer. No issues so far after 5000+ miles.
Well after about 2 years of umming and arrring I took it to a local place and had a downpipe made. It takes mk5 angled manifolds to the mk2 2.5" system, it has 2 flexi's right under the first flanges and 2 boss's for lambda probes. The 2 pipes join back together under the car about 9" after the subframe. It cost 120.
That is a bargain! Where did you get it from? This is my next consideration in the R32 saga, my options so far seem to be -Dubpower manifold but everyone says it has clearance problems with the steering rack on a corrado, for 370 I'd expect the right fit so that was a no. -C2 motorsport conversion, lovely bit of kit but a little bit more than I wanted to spend -Custom jobbie, but problem is getting the car to them (without an exhaust!)
I had it done here: http://www.tg-silencersrochdale.co.uk/ With all the engine mount option I think a custom one is a good idea. My rear mount is a trimmed Mk3 vr6 one.
I have a United Motorsports item on mine. Cost 330 delivered and I am more than impressed! Bit of a pig to fit with the engine in place, but I can hardly blame them for that! Main reason I went for the United Motorsports version was that it would be a straight forward replacement item for stock downpipe. I didn't really want a 6 branch even though they are a bit more free flowing, I wanted quieter, more standard sounding setup on mine. Horses for courses and all that!
