This thing is sweet. Fit like a glove, took about 40 minutes to install from the top. HUGE difference in radiant heat and sounds fantastic. The welds weren't beautiful, but they are strong. All flanges were true and bends/angles were right on the money. I would definitely go this route again.
great finish but the welds inside ports are horrible! they protrude heavily. if u really want
to make good use of this product, you may want to break out your dremel tool and match the ports up. doing so will void the warranty so do so at your own risk. I matched them up and hp gains are noticable all throughout the rev range. also got rid of the lean glitch at 3900 rpm. pulls clean all the way to redline. less bark than most headers and no droning frequencies. great product except for the welds/ports.
