well, my exhaust system had some ground clearence issues and 1 time I backed it out of my tent garage, and it got hung up on the ground from heaving and setteling.. It ripped it off, and the flex pipe I had coming off of the remains of the original pipe ( did that so I did not have to mess with the manifold bolts ) and the remains bent forward and kinked.. I'v since cut the pipe open so there is no excess backpreassure, but I can't run it like that... I'v always wanted Fentons, but always been concerned with the intake manifold as the factory manifold heats the intake. I know Fenton has a kit to block the intake heater and use water heat which I like, but I also notice that the Fentons have provisions for heat tubes.. what do I get to make this work.. I want to stay with the single 1bbl carb.
