Im sure this has been asked and answered many times but im gettin a 400ex soon and am gettin a pipe for it right away...i have it down to 2 pipes the Fat Boy 4 or Sparks...which one will perform the best and ill have the most power gains...or which one would you suggest..thanks for any help...

 

both are very good but i will go for sparks coz its slightly cheaper

 

yeah i was think along the same lines as you...both great pipes equal in power...sweet yea i think thats what ill probably do...thanks man...

 

not too sure abou tthe Fat Boy 4, but my freind has a SParx on his 400ex...and if i were you i would def get a sparx. ITs insane. A little loud, but very very very good pipe for the 400ex

 

sweet..yeah i though that was a sparks pipe on the 400ex...its hard to tell from the back but i guess i got it right...nice warrior man..how do you like the skin graphics...im gettin them on my 400ex...

 

yea i would to, my friend has one on his 416 ex and its sweet.

 

sparks is a great pipe for the ex

 

sweet... than thats what im gonna get...thanksi really like the way it looks too...cant wait..know i just have to get the quad..lol...
