My first PFR pipe (for a YZ465) but I wasn't impressed with the build quality of the pipe as I thought PFRs were considerd a high quality pipe. Welds looked sloppy/poor and too much use of brazing where welding would have been more desirable. The alignment of the piece that goes over the exhaust manifold and the first section of headpipe tubing was off. Kinda ugly all the way around but it came with a decent looking rebuildable alloy silencer. In fact, if the pipe was built as nicely as the silencer I would be very happy. Thoughts??
