I just bought a used 2001 400ex, completely stock with sand skate II paddle tires. Which exhaust is the best for riding the dunes?

I don't want to spend a lot of money. I hear Cobra is junk, and Yoshi are very expensive and not the best for duning ... what do you think?

I am an experienced rider, but this is my first 4 stroke and i need some help, the local shop will sell you anything to make a buck!!

Thanks

 

I like my WhiteBrothers pipe, but I think the Curtis Sparks makes a bit more power.

 

Dirt Wheels mag. did a pipe shootout a couple of years ago. I do not have that issue anymore. maybe you can find it.

 

CURTIS SPARKS !!!!!!!! no questions asked an awsome pipe. Amazing power gains throughout the powerband and sound great too. Harley like. www.sparksracing.com

 

I've got the Yoshi Titanium pipe and it does very good in the dunes, woods, snow, etc... Pulls strong from bottom to top. Any pipe will do just about the same thing on a 400ex if you get it jetted correctly.

 

Chads right...... The Yoshi is AWESOME on sand! its had a great power curve and sounds AWESOME!!Its worth every penny....Ive had Yoshi on all three of my Ex's...............TINA

 

If you are gonna leave it stock [bore & stroke, carb] Curtis Sparks X-4.

If you are gonna make it run correctly [bigger bore & stroke, carb] Curtis Sparks X-6
