I just got a 2000 400EX and it has the WB E-series slip on on it. I was just wondering if it is very restrictive and if I should change it for another exhuast. Is the DMC worth the $500? I don't have any engine mods yet either. Probably a 416 kit and cam in the future though. Thanks,

Nick

 

hey go to

http://www.geocities.com/gtthunder.geo/testbed_set.html

and check it out, they have about 20 different set ups as far as pipes, and jetting and othe mods to make your 400 run great.

 

I thought the WB was one of the better ones out there, is the 400 jetted properly? That WB is loud though, isn't it?

 

Im pretty sure its jetted right. I am going to play with it some though. Really its not that loud either.

Hey Derek, How do you like your engine mods? Im am planning on doing some to mine but not for sure what I am going to do for sure. I want it to be 100% reliable. I see your from IN. We should ride sometime together.

Where do you two ride at. I have been looking for people to go riding with.

 

A friend of mine and myself both had slip on's with the stock headpipe. I changed to a Curtis Sparks and he put a Big Gun that he got used. Both of us noticed a big change in performance from just the sil on's. I don't know if it was the change of the headpipe or having a complete system. I have heard that the stock headpipe was good, but they did run better with the complet system.
