Can anyone back up a slip on? Dyno results? I am gonna get one but there are so many to choose from.
I had a full Trinity and it did more harm than good. I ripped that hog off and went back to stock!!
The bike is stock except for the K&N and RW CDI.

 

without spark arrestor:

1. Horsepower Research End Cap
2. HMF slip-on
3.???
4.???

 

Who sells HMF, is there a website?

 

I gotta dissagree with HMF......I liked my FMF Square better. I'll take my endcap over the HMF, which finally broke right where the mount at the right rear just before the can starts. Big chunk, size of a quarter came out of the side of the pipe with the rear mount. POS.
Keep looking........FMF does more Dyno work than about anybody....

 

Alright so how do I get one of your endcaps?

 

I have the FMF Power Core 4 and it is an awesome pipe. The fit and finish is 2nd to none, and the HP gain was noticable.

 

Mr horsepower end cap bar none. 7 peak hp over stock, the only slip on that comes close is the HMF. HMF - 209.00, Mr Hp end cap 125.00, with jets, More power, less money, end cap!

 

I like my HMF. Loud, but more muscle down low. Plus the polished look is awesome. They said they are working on a new quiet pipe. They said though that anything over 400cc is hard to keep quiet AND make power.

Best bang for the buck.
