I have an all stock 2001 honda 400ex, what would be the best exhaust system to put on it. Looked into white bros r4 and LRD. Any suggestions or other brand names i should look into. If you have one and would recommend it how does it work for you, installation? Performance?

 

check out 400ex pipes they did a shootout for the 400ex, z/kfx/dvx, and raptor for like 10 different pipes, they'll help you figure out exactly which one you need. Just scroll down a little.

 

one pipe only sparks best for racing and all around riding

 

thx for the webpage, it was very useful.

 

the testing was done in 2001, and its 2003 now. A lot more is out there now.

 

Thats good to know, i will look into it. Thx

 

thats funny because i took a 400 with a sparks system on it, and i have a stock 400 (it runs like a piped one thow)

kc

 

WB e-series can't get any better than that if your looking to buy one i can get one for a reasonable price to

 

the pro mag full system the best you can buy

 

What is the difference between the White Bros. E-Series Pro Meg and The White Bros. R4 Pro Meg?
