Vforce - how loud are new exhaust systems?
I like the quality and fit of the HMF duals. But they are loud. I bought db meter ........... using DNR process,
( 20" from pipe at 45 degree angle, bike at about 2500 rpm's on the "A" scale ) they measure at about 100 db's
That is 100 db's WITH the "hunter quite cores" !!
I made a set of silencers to shove in the end of the HMF's that bring the sound down to about 95 db's ( that is
about 85 db's at 50 feet away.) Which is what it takes to keep the quite police off my back in this township.
I did not measure the stock exhaust system ( did not have the meter then) ...... but I would guess it to be about
90 to 95 db's
As for HP increase ..... I would say about seven hp with jet and air box mods. Turned it into a wheelie monster !
Hope this helps

You never rejeted!!! How are the plugs? Any studdering anywhere when you go WOOT? I range from 150 - 1500 feet where I drive, but mostly 500 feet or so. What did the MBRP's cost you, if you don't mind me asking? Dalton industries are using that same exhaust to do the R&D on their V-Force for clutches and stuff. I wonder if my dealer will be able to help me out here. I will have to call them this week some time.
Can you please get me sound clip of the exhaust? I'm sure your geek friend will know how to get it...lol. I bet your digital camera can record sound. Or get a video clip. I would also like to see how the exhaust looks on the V. Any discoloration on the exhaust. Is it overly loud?
Lots of questions, I know. You got me excited about the exhaust now...lol.
EDIT: Also how was the installation? How were the instructions? Hmmm.....I think thats it. [img]i/expressions/face-icon-small-smile.gif[/img]
