WB or hmf pipe?

[JR_rivard]

I'm looking to upgrade from a stock pipe on my 400ex and i was wondering which pipe is better. I do mostly trail riding and expect to hit up some dunes within the next year. So should i go with a WB pipe or hmf? I was also wondering if it is worth the extra money to go to a full system or just a slip-on?

the HMF is all around a better pipe then the WB. and the full system is deff worth the extra money but if u dont then HMF is the best slip on.
