FWIW, I put my 41016 Nova header and Dynamite 086HS pipe on my SH .28 P6 powered LST2 today. The pipe and header fit nicely, the muffler hanger needed to be made new. I used some .035" piano wire and heated/bent it to work. I only ran two tanks on this setup, but it did run quite well. A bit warm - 275F, but it ran well. Definitely faster than with the Losi header and Losi HT pipe. I still need to tweak it a little bit to get the needles set just perfect, but overall I'm pleased. I have some tranny work to do to the other LST2 before I install the Picco and move the
086/41016 to that engine and truck. Should make for an interesting experiment.
