Just curious, what is the loudest 400ex slip on? and header? like just loud header and a loud slip on?

My thought so far are the following for slip ons:
Fmf
White brothers r4
Hmf

headers:
?

i don't mean full system i don't know if this makes sence, and im not asking so i can go purchase a loud ***** system for my bike, i already have a fmf pipe with stock header and its loud already just curious tho cuz i hear some loud ***** ex's on the trails.

Also, can someone please tell me the db's my fmf is throwin off or a rough idea?? not sure what fmf i got tho hmm damn sorry

so by the sounds and majority, HMF is the way to go for the loudest pipe im taking it, ill hold off for some more pipes and stuff, i see the slip on hmf is 230 something as well.

Nor, is a slip on with a stock header as loud as or not as loud as a full hmf pipe? or are there a good combination, well what is the best combo touse for loudness???

www.supertrapp.com though they dont sell the shorty anymore, it is too loud for any reasonable use. You would have to find a used one somewhere.

powerbombs are made to reduce noise, they claim a 1-2 db loss. It would be louder with the stock headpipe just FYI.

Ruby Soho - They are only a supertrapp exhaust, even the old shorties were a modded supertrapp.
