whats the best 250 ex pipe

[honda250]

i have a 2001 250EX and i am ready to get a pipe for it after 6 months. What is the best pipe for it or pipe/full system over all????

My friends 250ex has a White Brothers E-Series on it and its awsome.He can wheelie in 3rd gear and it sounds great.Get one off of Ebay for 190$.

I have the WB E series slip on and it made a huge difference over stock! It so much easier to wheelie and it feels as if it has more power!!!
