I'm a noob to racing and bashing . I have a great time putting together the hpi baja 5t . I've put a ONB g340 on a 38 lbs 5t running 19/55 gears and used a DDM fast pipe because I like the rear exit. It's fast but not what I expected after I broke it in . Lots of midrange .I'm looking to change the pipe. Can someone recommend a pipe for the figure 8 track, or is my gear to high?
