what is the best slip on pipe for an 03 400ex

 

The one that you feel you got a good deal on, and are happy with its performance gains.

There are many out there, and you will get as many opinions as there are stars in the sky.

The more popular ones seem to be Sparks, White Bros, Yoshimura, HMF, LRD, and the list goes on and on.


I had a Sparks X4 full system on my 400EX. The gains were decent, but the sound was deafening, even with a helmet. I then switched to a Yoshimura slip on. I didn't seem to lose any noticable power. The only difference was that I could hear out of both ears when I was done riding. The Yoshi had a nice deep sound, and gave decent gains. Just my opinion.

 

ya but what slip on pipes do u guys like best on your 400ex's. best power, top end, mid range, and do not seem to break

 

for slip on's, hmf seems to rule the roost.

 

well the yoshi is good but i swear by the white bros e-series i did the research and it gives the most all around lots of out the hole power very good mid range and a few more mph on the top but if u r going for mostley mid and top i would go with the yoshi i have had both and i kept the e-series and sold the yoshi then got the header for my e-series and whoa lot more on top end so again go with the e-series u wont be let down.

 

o ya i forgot i ride a 300ex and keep up with the 400s
