My E-Series cracked where the pipe enters the can. They are pretty well known for thier quality (poor). But i do like the pipe. Love the fact it is adjustable.

 

i have no complaints with my sparks. i am surprised to hear the hmf broke. if i was to buy a slip on, i would be getting hmf no questions asked.

 

I think he said he had an FMF that broke.

I just got my HMF yesterday so I'll have have to let you know later about how it works [img]i/expressions/face-icon-small-wink.gif[/img]

 

good catch about the FMF, not hmf.

 

i got a hmf slip on on my 400ex, its great, tons of power and sounds kool [on the loud side tho] it is just as good as my friends Dg full system and the hmf comes with the rite jets for an extra 5$

 

I think HMF is the best pipe for the best price also....$209-229.. And dyno show it has better performance than the E-seires..Plus it look a whole lot better and the sound it AWESOME....Oh ya plus there are a bunch of different colors to choose from...hmfengineering.com
