i would go with the hmf cause my friend has one and he talks about it all the time and so i never here people talk about white bros so my opinion is get the hmf plus u can get it in any color u want

go with the hmf, it gives more power because you dont have the plates to slow down air flow.

Where's the best/cheapest place to buy this HMF system and does anyone sell a full kit for a 2005 400EX yet?

Got mine from lessons $239 with red powdercoat. Got it overnighted for $279. Its just a slip-on though dont know how much for a full. Plus it comes with proper jets and an air filter for free.

plates, psh who needs them,, i run an E series BLANK NO DISCS just end cap and it restricts nothing, sounds nice as well,, also restriction in a pipe can be a good thing because of back pressure,, HMF is a good pipe but think before you speak,, white brothers dont have to have plates if you dont want them to,, plus, they also have different end caps you can purchase for them to make them look better. i have not had the imfamous crack before muffler or anything so i guess thats why im satisfied.

Hands Down the HMF is 1000 X's better than any WB pipe.. You cant go wrong and they will stand behind there product unlike WB's... I have had both and would NEVER go back to a WB's pipe.. jmo
