What kind of exhaust should i get for 400

I have an 2005 Honda 400ex it is the Yellow edition.. I was wondering if the pro circuit is the best exhaust for torque and power?... And I was wondering why they did the yellow for only one year?

First off, welcome to QUADCRAZY! Have you looked into FMF Pipes: Products - Bike Finder - FMF Racing

I believe Stoopidbot has a 400EX and races, he may be able to tell you.

I have a 450, but Curtis Sparks makes an amazing pipe for the 400EX. HMF makes AWESOME pipes, FMF is another great brand that doesn't break the bank.

fmf man load and helps the speed

I have a Curtis Sparks on my 07 400EX. It is a great pipe.

I run a Lexx exhaust on mine and it's sweet exspecially for the price.

Lexx is a good pipe, It is a knock off of Yoshimura's older design

hi i have fmf on my 400ex and it sounds very well. dont tink dere is much between dem power wise :)

Be careful how much noise they make! Many states are enacting new, lower noise limits. Oregon, for example is 99 statewide and 93 at the dunes. They are soon to go 93 statewide!!! that makes MOST aftermarket pipes worthless..... so be careful you dont waste your money. You might check with a local ATV club and see what's planned for your state...
