2 Brothers Exhaust... What the difference ?

[Yehbaby351]

Alrighty ive been doing some research on 2 Brothers Exhaust Systems for the FZ6R.

I really want to get one but im getting confused a bit.

Some are carbon fiber, some are stainless, some are titanium. ( i gather thats the muffler part)

But im also seeing there are the standard full system and the V.A.L.E system.

as well as silver series , black series, m2 series....

WHAT IS THE DIFFERENCE.

Do they all sound the same or does each setup give out a different sound or noise.

What have people used and what are their reactions.......

I really hope you get a few replies. This is exactly what i want to know!

The only difference is in the finish of the baffle canister.
The VALE system is a number of reducing inserts to restrict the amount of exhaust is emitted, and thusly noise too.
2Bros is the most common system sold for the FZ6R, IMO it's only due to the ease of finding them.

i recently installed the black series 2 bros full system. from my research they're basically all the same with the exception of the finish on the muffler. the inserts basically control how loud the exhaust is. mine came with the p1x silencer which is a good medium, not too restrictive but not too loud. sounds very good compared to stock.

if you do get a full exhaust such as the 2 bros you should also consider installing a power commander to tune the engine for the exhaust. you might also need block off plates to suppress popping sound on deceleration. i've done all the above and loaded marthy's adv rev gear map via the power commander. makes a noticeable difference in power.

Will definitely put a power commander on and also the fuel tuner as well as i have been told with that , you wont need to get it dyno tuned....

So does anyone know what set up is the loudest and which one is the quietest out of the 2 bros exhaust range. Or is it just removing the plates or inserts to make it louder.....

So when you say block off plates..... where do they go... and can you buy them online....

The block off plates cap off the air intake system inlets that have to be removed. The ais I believe helps burn unspent gas as part of emissions (cat is removed since it's part of stock exhaust). Not needed once stock exhaust is removed. There will be noticeable popping and flames if you don't put the plates on. Can buy them almost anywhere online. You have to remove a screw holding front of gas tank on and and prop it up or remove it completely to get it out of the way (also need to remove driver seat first). Then remove Airbox and the ais is under the Airbox. May also need to remove the inner fairing pieces (the ones touch the sides of the tank) one screw and Pop rivet each).

most people leave out the fuel tuner/autotune. marthy's maps have been dyno'd and there seems to be a general consensus the maps are good enough that autotune isn't worth it. as for loudness that's determined by the inserts. no insert is the loudest. the p1x insert that comes with the exhaust is a level down, but still sounds good and reduces exhaust drone on the hwy.

scott covered the block off plates. if you're handy with a set of tools and patient the installation isn't intimidating as it might seem. mistaht also has a few youtube vids walking through exhaust and block off plate installation that were very helpful for me.

It's the tip that determines how loud it is. That's one of the best features of the TBR systems. You can run no tip, a P1 or a P1X. All sound great, just different volume levels. I had one (black series CF) on my 6R and loved it.

Australian bikes have an O2 sensor were as American bikes don't, so using Marthy's maps in a P.C V won't work out the same.

Has anyone got a IXIL system? I think the Dual Hyperlow looks great. Is TBR better? Or just the most common because it's easy to get?
