how good are they cause i am thinking about geting on to put on my 250ex help me chose the right pipe

 

It's a good muffler for the little 250. I run it with 8 discs and a quiet core, UNI air filter, and four UNI airbox vents in the lid. It gives a noticeable increase in power. You will get even more if you don't need to run the quiet core.

 

i would look elsewhere. i would actually look into the HMF but it is just all opinion.

 

Im happy with mine on my Wolverine. I run it with 10 disks and no quiet core and a K&N filter and holes in the airbox lid. its got a nice throaty sound isnt quite as loud as my buddy's full open yoshi system on his warrior.

 

i have one on my 250x and love it its soungs good and gives you alot of power increse youll notice a big difference when i drag no discs when i ride trails 13 discs its great
