Just give me your opinion. Even if you like something else. I'm looking for sound and low-end power. Thanks.

 

I really like my HMF. gives good power and is very well built. [img]i/expressions/face-icon-small-wink.gif[/img]

 

did you notice anything except more noise after the slip on, power wise?

 

I had every thing in my sig before I put the pipe on and it gave really good gains in power.

 

Had my WB E-series before adding the K&N and dynojet and there is really no comparison in the before and after. You need all 3 areas to maximize your gains.

I've own a ST before too and I thought it was better built than the WB.

 

i have a wb e series slip, my opinion, its the best slip on u can by, dirtwheels magazine also said that, u can buy a used one for real cheap and they give alot of performance gain in the low end, if thats what you are looking for, i took all of the discs off the end of mine, i like it better like that, no discs to clean out and the sound isnt that much louder

 

They have been fans of WB for 20+ years. Think it has mostly to do with advertising dollars.

The test I saw, the ST put out out as much HP but was louder. I can't recommend the WB because mine and several other people's have cracked where the pipe meets the muffler.

Haha I thought these dirtwheel's quotes would stop...

I Like the Hmf power gains and sound.. They give you correct jets and there at a good price.. Go hmf And ride hard

 

Like raptorlegs said the E-series is a beater. Mine is cracked and my wifes broke completly apart. There is only one reason you could buy on cheap.[img]i/expressions/face-icon-small-wink.gif[/img] The pipe is a good power gain but the E-series is the only one I have heard having quality issues.
