i was wondereing how loud the pure polaris pipe is

 

It's under 96....sounds good. Sounds even better with the turn down end cap!

 

well i have the white brothers e series on my 400 ex and the pipe is pretty much exactly the same. i put on all but two of the disks that came with it and its loud. Louder than my FMF power core 4. if the pipe is pretty much the same it is around 96 db kuz thats what the e series is supposed to be. the loudness isnt bad tho, it has a really cool sound to it, low and deep but not annoying. sounds wicked when ur wound out in top gear.

 

Yes - I think it is a rebadged WB S bend pipe
Tell me "flyin400" - have you tried the pipe with no discs at all and just the angled endcap (another words just straight thru ?)
I've just got one and was wondering how that would compare to your setup.
Do you have the blanking plate on the end ? - as if you dont theres no need for the discs is there ?
Please help !!

 

i tried it without the disks once and it got way too loud and hurt the ears. yea i do got the end plate on but if u dont have it on there is no point in putting on disks kuz it would just go right thru anyways. hope u like ur pipe
