which is louder for a 04 prox 700

mbrp
ceramic coated dynoport

MBRP is loudest. get "the thing" from www.thesledshed.ca

gain HP with the thing vs losing with MBRP. just as loud

i say rumblepack

rumblepacks melt things in pro-x's

mbrp sounds nice .

Ported mbrp race can, lol. JK.

You want loud, hook a hose straight to the pipe stinger and pipe it into your helmet. Then you wont be bothering anyone else. I still consider myself young, and can't understand why people like ringing ears. I hate getting off a sled,bike,etc. and having to say "huh" for the next hour, LOL. I absolutely love my new SLP ERA 2007 silencer. Has a slight bark at WOT, but is very, very quiet when cruising.

if loud is the game the "Thing" is the loudest best sounding i've heard... it borders on open stingers at full honk... but i'm like Polaris Nut, i'd take the SLP 2007 can... sad truth of the matter though is that the stock one likely makes the most power and i'll take the 5lb weight penalty instead of the HP loss most of the other will give you... HP is more important than noise imho

i run a dynoport on my sks and the thing is LOUD! i've havn't put it next to the MBRP yet, i'd have to say you could honnestly hear me commin from a mile away..... and it's a low rumble. sure turns heads at the gas station when i fire it up

how? explian...

if i was going up for a long ride to the tug hill i would slap on a slp 2007 series can they are nice sounding but i local trails around here and in feilds i ride in i would slap the mbrp trail or race can on. cops are not around this area much i seen 2 yesterday for my first time in my area they were riding polaris indy trail 440's i could dust them... but thats what i would do.

Wonder what their thinking (really) when they turn their heads? Noise does not equal horsepower!

The best and loudest can out there that is very cheep is called a Fosters beer can. Just buy one drink the contents, then afix it to your pipe. lol
