Has anybody else had to deal with Pro Circuit? I used to be a fan of the PC pipes, especially the 2-strokes. But in dealing with them the last couple of years and the latest with a 496 muffler, I probably won't buy another PC product. The 496 performed ok with the exception the muffling capabilities were lost rather quickly. I went to re-pack the muffler and all the screws are frozen and being of poor quality they snapped off fairly easily. The muffler leaks at where the header pipe and muffler come together - apparently there isn't a clamp for that. It is supposed to fit tight. Right. Since the PC 496 is one of the more expensive units, I expected more. FMF is getting another customer and PC can ES&D.
