I have a new double walled pipe, I wasnt going to mess with what came with the kit. None of my other jets have a vent like that but they also dont have a bypass. Ill add it in.
I used some bvm pinhole filler for the first time today, man that stuff stinks bad. Even after dry and I wipe it off the part is still spittin out fumes. I cut out the splitter plates and glassed them, thought Id give it a try for weave filling. Jury still out, it leaves a rubbery feeling on the part and once again IT STINKS!
