yeah the best pipes for this application don't get made for QT's, either a good scooter pipe like a leovince or an MLM or Crank pipe all designed for puchs are your best bet. The scooter pipes and stuff like doppler and giannelli for variated bikes might not have the grunt to get you rolling depending on how your clutch tuning works out.
i haven't worked with that malossi kit in years, i put one on a hobbit once... and that is assuming its the same porting as the hobbit which i think it is.... it was overwhelmingly meh. i'm not even sure if it will make enough power to light up a big pipe. Unfortunately that is going to be the weak link... like putting 2" primary headers and a 850 holly on a high rise on a smal block chevy but then putting a stock cam in it.
unless you are planning on some kinda wizard porting using dental tools and stuff, that is really going to throw off the build. Maybe a tomos tecno estoril? those perform well on lower output cylinders. At some point you cant raise the exhaust anymore because you'll have too much blowdown and the transfers won't be big enough to keep it from stalling.
If i were you i'd weld up the cases and adapt right away for a scooter cylinder with good aftermarket support like a minarelli horizontal or something (if the stroke comes out close, which i think it does, you can fudge it with porting and the thickness of the spacer) then start with a conservative either 70cc or 50cc mildly ported cylinder, which you can swap later for an aggressively ported full race cylinder. There is also a lot of H20 cylinders for those platforms, but for drag racing you shouldn't need fan cooling or anything. Worst case scenario you can put a electric fan on it or run a leaf blower on it in the pits. just seems like trying to make this whole build work around a really crummy cylinder just because that is the only one out there, really limits the potential.
