Thanx for the input. Everyone around my way seems to have Yosh or Mic on their RRs and I am not a fan of the sound. Looked into getting the 2 Bros. Now I am trying to find the diff between the M2 and the M5. Anyone??

 

[We offer three distinct canister shapes to choose from; C2 (small oval), C4 (traditional round 4.5� diameter) and C5 (large oval). All of the canisters perform and sound the same because all of the canisters feature the same 2.25" Stainless Steel Spiral Power Core. The core is what controls the power and sound, not the shape or material of the canister. The canisters are simply different styles. They all incorporate our exclusive technology and premium construction material. The different exterior shapes allows you to choose the one that best fits the style of your motorcycle. For instance most people prefer the C2 (small oval) with smaller sized motorcycles (like 600cc machines) while others prefer the C5 (large oval) with larger sized motorcycles (like 750cc or 1000cc machines). For those who prefer round canisters we offer the C4 (round).]

Sorry, I couldn't get the pictures to copy over, but if you go to http://www.twobros.com/cgi-bin/shopp...600F4i-SO.html scroll down to the bottom and you will see what I'm talking about.

Good luck! I love my 2 Brothers on my F4i!

 

Thanx for the info. I guess I will go with the 5 to better fill out under the rear of the bike. I saw the C2 and C5 explanation on the 2 Bros site but didnt want to assume the diff was the same for the M series. Since you seem to know a bit about the 2 Bros (in addition to having one on your F4), what is your take on the sound level. My initial post describes what I am looking for, not so much power increase or appearance. I normally keep my RPMs in the 6-9k range in case I have to act on the actions of a 4wheeled moron. Thanx again for your help. Be safe out there.

 

I have A 04 600 rr my first bike came with jardine slip on not figuring it would rate too well for quality but just wandering how other people would rate it

 

I was looking at two bros and D&D, the thing that pushed me towards D&D is the finish, and that no one around here has it. It's all Yosh, leo vince, and 2bros(mainly 1k's) i like loud. But if D&D turns out to be too loud i will just sell it and grab a D&D. Considering i got it at cost i can still sell it for much lower then any dealer and put money in my pocket afterwards.
