hmf is good or the white bros e2

 

Is pro circuit good [img]i/expressions/face-icon-small-cool.gif[/img]

 

i dont know but a lot of people have them .

 

i got a question for all you hmf owners... how loud is the pipe over stock with the spark arrestor and quiet core? im thinking of gettin a quieter pipe

 

mine is 98 db s with out the quiet core..

 

really? damn thats sweet

 

what about supertrapp

 

I have the Supertrapp IDS2 on my Rancher and really like it. Many people will tell you it's junk though. It is a little throatier than stock but one of the quieter pipes out there. Drawbacks to it are: the allen bolts that hold the disks in are prone from striping due to the heat so put a lot of anti-seize on them. The power gain with a jet kit is good and I like the look of it.
