I Have a 04' R6 and i was wondering what the best slip on would be 4 the bike...i mean performance gain wise. i want loud 2, the guy at my local yamaha dealer told me that the D&D is crazy load and there is nothing like this but performance wise isint 2 great so any 1's comment would help......thanks

I got the same bike and am looking at picking up the blue flame from hammy. Sounds good, Looks good, and from what i've heard it gives some boost.

I woudl say stay away from D&D., I have one on my bike 02 r6 and its sounds like crap, Its been described as soundling like a " Pissed off bumble bee". I think it sounds more like a ricer honda civic than a bike.

Wolf exhaust is the best exhaust and he can make them louder for you if you ask.
Wolf all the way.

well like adhem said above, wolf makes a great exhaust which will boost performance, and i have a blue flame hi mount on my 04 R6 and i felt a little boost from it, plus it looks great. i know M4 makes a good exhaust but they arent loud. :cheers
