full exhaust or slip on

[exridr400]

Is it worth the money to buy a full exhaust for a 400ex rather than a slip on

the pipe would be a hmf

I have a HMF sport series slip on and its great! It gave me alot of bottom end power. If you have some motor mods than buy the full system. Check ebay because i got mine for $200 new. It came with the quiet core, jets, and a spark arrestor. It will be twice as much for a full exhaust.

They sound awesome too!

It's just a little piece that goes in your exhaust that stops most of the small embers or little fire things that come out. I think you have to have one if you ride in state parks, so you don't catch the woods on fire. lol

quiet core self explanitory?

ya...pretty much. I put the quiet core in and i think it gave it more "deep tone", but was not as loud. the quiet core has a built in spark arrestor too. My dad made me put the quiet core in but i took it back out...i like how loud it is!
