I was wrong. Big Gun states that 51hp was at the rear wheels on the FX. And they will have a run on paper with the Moto Mapping, but it's close to 53hp at the rear wheels. I have the FX400 dyno in my yahoo pictures now.

 

I just got off the phone with HMF direct and the lady said they haven't starting makeing the pipes for the cannibals with the sqaure one? Is this true? Does anyone make a pipe for it yet?
thanks

 

No, nobody has a design that will work with the new square silencer. From what I gathered, HMF is only going to offer a complete system as an option to the square exhaust design. They will still have the slip-on type for the old headpipe design, but do not plan on offering a slip-on for the new headpipe design. It'll run you about $400. Someone correct me if I'm wrong on this....

 

I inquired about my HMF slip on for the square silencerva couple of weeks ago and was told around July 1st. Now you've got me wondering....Atvaddiction has a bunch on order..

 

jcv400ex, I could not find the dyno Big Gun numbers on your photos.yahoo.com page.

 

It was out in limbo. It's under the "Cannondale" folder now.

 

so are you guys saying that in order to use a big-gun silencer on the '03 dales you'll have to purchase the head pipe from them too?


jcv, your dyno still isn't working.

 

JCV - thanks for mailing the dyno to me, but are you sure it's accurate????? I mean 51 HP seems like a WHOLE LOT of gain over stock. I honestly find it hard to believe that a pipe and mapping will give a 12-13 HP increase.

 

That's on a dynojet. Cannondale uses a Superflow. They say it's legit.

 

So I wonder what the HMF with a remap would show up on the Dynojet dyno? Probably be about the same as the Big Gun I'm assuming??
