Best pipe for 400ex racing? Sorry guys

[Stevo]

Hey guys im getting into racing next year and i'm gonna get a pipe now. I wanted to get a wb e-series but i have heard of them breaking. Is the r-series more durable but pretty much the same sound.

Also how are other pipes such as fmf, ct, etc. compared to the wb?

if you plan on getting your motor built i would go with a motor builders pipe like LRD. that;s the one i like

i like t-4

Rico runs a Bills Thunder on his 416. Might check out Hetrick and LRD also

I don't know if it's the best or the fastest,,but it works for me and it's different from all other setups i've seen.

My motor is all stock and it will probabley remain that way. I just want a pipe that sounds good and won't break.

i have a sparks x-6 , it sounds freakin awesome, like a harley davidson on acid ( my friends discription ) . its tough as **** and it really seemed to have waken my motor up with a filter and a jet kit. 3rd gear wheelies seem to be much much easier now that i have it on. call me one day and ill let you listen to it haha. it seems to be sturdy too. i havent heard of any1 having a broken one yet and it looks great 2. only problem ive had with it was my own fault . i had on my free ride oneal apocolypse gear and my pants leg melted all over the header. but i scraped it off with a razor. i took some mother alluminum polish and went to work on the scilencer and boy is it bling blingin. anyway , i hope this helps.
