Hello, I hope I'm not out of place but I coudln't think of anyone better to ask. I've been trying to do a lot of research and have some questions. I just bought a os .91/Dynamax/JMP Pipe is there a exhaust gasket that goes between the header and the cylinder. I'm building a ground model (boat) with this setup and I need some help on some things (who better to ask than you guys). Mainly mounting of the fan and engine and ducting "thrust tube" (single outlet) setups. Is there a tube that I can buy that goes in a jet kit or is it possible to make my own? I have no kit and designing everything myself, which I've made quite a bit of progress on. Some pictures of DF setups (mounting/tubes/etc) would be great! I've ran accross a few cause I've been searching like crazy. I just purchaced all the imporant stuff. Tanks, Tubing, Tee's, Wildcat 5% DF, Mc Coy 9's, etc. etc. If you can think of any information that might help me please let me know. Again I hope I didn't step on toes posting this here. If so delete. Thanks.
