hey, I have the 350 grizzly as it was what dad could afford, what are some good mods to do to it.. It is a 2007 grizzly 4x4 with IRS and a diff lock.. It needs more low end wheel spinning torque.. preferably cheap or free mods, I know a pipe would help, but anything else... also, could a manual tranny be mated to this motor? just curious.. is there a baffle in the pipe? I would like to mod that aswell, or a governor/ speed limiter hidden somewhere?? thanks.
