Anyone know if adding a proformance muffler to a 1995 400 foreman will make a difference in power. I've read you have to rejet the cab. and this can be tricky. Just curious if it's worth it?

Thanks

You will be able to notice alittle power increase and yes it will have to be jetted.

i jus got a hmf for my 450 i can deffanitly tell a difference in power and if u buy a hmf it comes with a jet and after u install it it will still run a little off so u will hav to mess with the air/fuel misture screw and the idol to get it rite .good luck!!
