The Zork tube looks very nice, weld quality is good, easy to install and well packaged. Unfortunately the one I received had a defect on the outer lip probably from grinding.
Beautiful piece. Well packaged. Fit and finish is exceptional. Also exceptional was the delivery time(Standard shipping). Felt like the next day after placing the order it was on my door step! Seriously, I order everything online and no company has ever turned around an order with such speed! Perfect in every way.
Very nicely fabricated and robust piece. As there is no chrome on my car, I elected to knock down the polished finish and coat with VHT header paint. If it doesn't hold up I'll go ceramic coating. Have not yet installed. Looking forward to hearing it.
