Honda 400ex Exhaust

Hello i have a 2001 honda 400ex all stock and want to get a better exhaust. Something that is really loud. My friends told me big gun or hmf would be good which one is the loudest of the 2. And they will be a slip on.

Welcome to the forums.
Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

I just bought my curtis sparks exhaust today. if you want i will take pics if you want. I would get curtis sparks cause every place I read it says they are the best for the 400ex. I personally think they are sick as hell looking lol

Also I got a dyno jet kit with my purchase that way I can have it running good with the new exhaust.
