Power Bomb Header?

[TeamTaylorRace]

I just bought a new 400 EX today, and I was wondering how much difference the power bomb header made?

it will be better than just the silencer alone, and powerbomb is the best aftermarket pipe, one of the only ones available for most silencers. but yeah, its worth it, i made the mistake on buying the silencer the first time around and ended up selling that and going to a full system and it made a big difference. about 2 bike lengths ahead of my buddy i sold the silencer to.

you will me fine with the stock unless you are going to do some motor work....Than you will feel the full power that its going to give you.

I've heard alot of good things about the powerbomb. Some people on here said they just bore the stocker out and it works better than most aftermarket headers. I remember one guy said they only use the stock header on there trail quads because it offers better lowend response and torque then after market free flowing headers.
