Two brothers is the way 2 go for ear ringing pipes lol.

 

D&D are very loud, also devil.

 

I would go with Sato or Arata for the best sound, a loud pipe is going to get old quick.

Just my.02c

i think shorty pipes are the loudest you can go... you can go on ebay and get one for 50 or create ur own from exhaust tips at the auto store which i have seen been done before

 

2 bros has the loudest in general. The downside is the HP increase is only "OK" and they look like a little kid made them. They look especially ridiculous on bikes with the underseat exhaust, unless you're going for a streetfighter look.

 

hey guys i like this thread...i was looking at 2bros and D&D. I have a 08 1krr and want a loud *** pipe. What pipe would you guys think is the best of the 2?

 

I just had the opportunity to hear this two bros on an 06 1000rr and it is sweet...brings tears to your eyes.lol....if you get the fender eliminator kit that only has the exhaust and tag holder...it's ugly, but if you keep the factory covering around it, it looks pretty nice....Overall most slip-ons will only give you 3-5 hp, which is still good for a bike this fast...

 

Ive realized that the akrapovic full exhaust (not just because i have it, but from an objective point of view) is the BEST overall exhaust for the 1000. Power wise, sound, quality, looks - it has it all. I love the sound as well, its not obnoxious like others i've heard on my same bike - but above like 5000k it screams. If your choosing an exhaust, I would undoubtedly recommend Akrapovic for this bike

might not be as loud as two brothers but one guy in las vegas has it and you KNOW when he is pulling up to a motorcycle event (very unique and loud exhaust)

downside? expensive

 

I like a loud exhaust too b/c one it sounds good and two people hear you so it's like a second horn. I just got my 08 CBR1000RR and I had a Jardine RT-5 slip-on installed. Wholly crap this pipe is loud almost too loud. Someone here said it before and I think they're right because of the moto gp style short pipes on these bikes I think most of the aftermarket exhausts are loud some just a bit more than others. Just cruising at 60mph this Jardine is screaming. I thought my Erion slip-on pipe on my 'ol 929 was loud this pipe makes my Erion seem quiet. Try the Jardine it sounds awesome at idle and cruising.
