seems like of people are running erion,, what kind of numbers are you seeing with the erion?? i bought my bike with a d&d on it and dont get me wrong i like loud exhaust but ever since i rode around the block without my helmut i feel ke im giving up good sound for loudness.it kinda reminds me ofa civic with a 6" pipe sticking out the back at low rpm cruising.but i still like dont get me wrong if you want a LOUD *** can buy a d&d,but i want loud and id would rather it remind me of a F1 car than a civic

 

i have a two brothers can and i am thinkin of getting it shortened because it's not loud enough for me.

 

I have the Erion Racing pipe and i think it sounds pretty sweet. I wont change it.

 

yoshi R&D . at idle (and low revs) a lil bit more quiet than i would like but once you get moving it sounds awsome

 

Two Bros carbon fiber

 

I have got a full system Akrapovic on mine and I love it. Not so loud riding around town but when I get out somewhere and open it up it screams!!

 

I went back to a stock can after having a D&D. What an amazing difference. One of the things I noticed is that, for me, the bike is easier to ride when it is quieter. I guess I am putting more attention into the ride than worrying about if any police are nearby ;-)

 

Akrapovic and sounds awesome IMHO...

 

My pipe isnt on the Vote list?????I got Quill pipe on mine, i love it and its loud..dont know if you guys heard of Quill. a lot of riders ask me about it,a brand fromfrom England.

 

mine came stock with the erion bolt on. wasnt loud enough so i pulled all the packing out. love it now. loud and deep
