I am trying to decide what pipe i am going to get. I have a 2002 honda 400ex that is completly stock, some of the pipes im looking at are the big gun(race), white brothers e series or a pro circuit. The only riding i do is in the sand and i want a pipe that will help me with hill climbing and drag racing. I am 15 and about 6'0" and 145 lbs. im gonna get a k&n power kit with it too. Any suggestions???

 

The exhaust that you have listed are good but you should look into Trinity or Yoshimura and CT they give the best power.

 

Try the Duncan Fatboy4. Worked awesome for me. It's a little pricey!!!!

 

This topic has been gone over quite extensively. You should probably reserach it. However, just to help you out if you are not going to do a big bore then get a Sparks X-4, if you are going to do alot more mods to it then I would get the Sparks X-6. I have had both pipes and they are both very good. Personally, I dont see much else than Sparks at the races.

 

Yoshimura and CT are the best running pipes in my opinion.

 

Id say the Sparks X-4 pipe is the 1 of the 2 best for a stock or midly built engine (as said earlier) and the X-6 for a fully built motor. You might want to give Thunderalley a call to they give huge torque and HP gains. They are located in central califorina and are priced at 350 for a complete system. I have 1 for my 400 and it rips! here is thier website which has thier phone number www.thunder-alley.net ...hope this helps!

Keep in mind how much noise each pipe puts out. If you can find one that keeps it quiet and still puts out the power then go with that. I'm still running a stock pipe (Worked over a touch) on my Raptor and keeping up with Raptors that have Big Gun pipes!!

I like to keep my bike quiet... especially at Florence! They get a little touchy down there. If you're just going to Sand Lake... I haven't seen a problem.

Good luck!!

 

I caint recomend the Trinity more. I love this exhaust! The one thing that is bad is its a little loud.[img]i/expressions/face-icon-small-happy.gif[/img]

 

I decided to go with the Big Gun only because i got a really good deal on it, it was only 175 bucks on Ebay. Thanks for all of your input i appreciate it.

 

i would say either the ct racing pipe the yoshi or the white bros e series
