I personally dont know what the M4 sounds like but the devil pipe sounds real good if you ask me.

 

i really like my m4 high mount but i havent heard any other aftermarket pipes on an f4i. it looks great to becuase the can follows the lines of the tail of the bike.

+1 on two Bro's. It gives you looks, sound and everything else.

 

+1 again on two bros.
My bike had a D&D when I bought it...that was toooooo loud and buzzy for me.
Found myself getting headaches from riding [:@].
Bought the two bros. Best money i've spent since I bought the bike!

Well no one is speaking up for Yosh - which I am not surprised - so I will. They're older (relatively speaking) and somewhat played out - seeing as though they have been around for quite a while. But I love my TRS - nice look and great sound. My friends say they can hear me from about 3/4 mile away if I'm really gettin' on it. But it's not obnoxiously loud - obviously, it's a Yosh And the quality/workmanship is also top notch. The only thing I wish I would have done differently was bought a high mount - hence I would go either 2 Bro's or Devil.

It's all a matter of 1) personal taste and 2) BUDGET! At the time, budget was controlling my decision moreso than "taste".

 

Yosh isn't an option for me, not to say I think there is anything wrong with them, I just think they sound too high pitched, and that's not what I am looking for. They are durable tho my friend has one on his R6 and the last time he went down, he dented ands scraped that sucker up real good, but no leaks.

I am fairly certain I am gonna go with a Two Bros, just not sure which style yet.
