[QUOTE="reepicheep, post: 1421198, member: 104942"] So I'm getting ready to rebuild a KX-80 that came in a bucket... crank is on the shelf, head is on it's way to Eric Gorr, and I found a cheap FMF fatty pipe on ebay. That leaves the carb (another thread for another day) and the silencer. The easy answer is to just get an FMF Q series. $140 or so. No doubt a great choice. But I'm always looking for an excuse to weld, and can weld aluminum, so I'm wondering about tweaking the stock silencer. This will be a woods bike, so low end power and quietness are my top priorities. I don't mind top end staying the same, or even loosing a bit. I initially assumed I would be doomed for a DIY two stroke exhaust fabrication. Way too much voodoo math there for a hack like me. But the more I dig, the more the voodoo seems to be concentrated in the header pipe, which I am going off the shelf FMF for. The silencer seems to be an afterthought, and robs power for sure, but nobody seems to talk much about silencer volume (or if it matters) If I took the stock pipe, and grafted on another baffle at the end, or made the pipe have a higher volume some other way... would it really matter in terms of performance? I'll probably just buy the FMF Q series pipe, $150 is a bargain compared to the time I would have to put in to make something that would perform as well (and that assumes I have the skill, which I don't). But it's interesting to think about. [/QUOTE]
