Two Brothers M2 Slip-on

All right, Who has the Two Brothers Racing M2 slip-on. Im thinking about buying the carbon fiber one but I wanted to here what some of you had to say about it. Is it any good? Power gains? Sound?

I have it, the M2h, love it, very loud, deep tone. Not D&D loud.... but you hear it.

So it does sound good. What about power? any gains? oh and with the carbon fiber it keeps a little cooler right so can I take off the heat shield above the muffler?

I have all of the heat shielding removed and I've made several longer trips (over 400 miles non-stop) and I when I do ride, it's all day long. No heat damage at all.

Performance... maybe 3 or 4 HP. I did my dyno after all the mods were done and it showed 109.something. The guys running the dyno said they never ran a stock 600 with anything much over 100.... they said they're usually right at 100 or 101, 102. So with the slip-on, PC III usb, filter I maybe added 8 or 9 HP to the bike.

Which I personally think was mostly due to the PC III usb. I was running a -1 in the front to give me a little more in the take off area, but I'm happy with stock gearing (most of the time) with the PC III.

The sound... everyone loves it. I use to ride with a couple guys that had 600RRs, one with a Jardine and the other had the Yosi RS-5. They both wished they heard mine before they ordered their's.

It is louder... like I said, not D&D loud, but I like it. Here's an example for you. I'm in the middle of a major move and looking for a house. I keep my bike at my dad's in a nice climate controlled garage until I have a garage my bike can call home. He lives in the back of a subdivision and can hear when I enter the subdivision a mile away. Now, if I'm just rolling at the speed limit... you can't hear me that far away. But when you open it up... you're not sneaking away from anyone.

Thanks man that helped my decision out a lot. Do you know a website or anything with the cheapest prices and how much did the PCIII run you? Cause that seems like a good idea too. What brand of air filter are you running cause thats on my list as well. Right now my bike is completely stock engine wise. I have different rear turn signals and a fender eliminator from Ride Engineering but thats about it.

I went with K&N air filter mostly because it's reusable. Just clean it, oil it back up and you're good to go.


I paid about $280 for the PC III usb from here

I ordered the 2bros with another member here on a group buy from one of our sponsors... about $450 shipped I believe. You can do a search and find it any where for about the same price now. We bought them when the going price was over $500.

Wait until others answer your question about exhaust to make up your mind. The RS-5 looks damn good, it's a little quieter and not as deep tone... but that might be what you're looking for.

Actually my sisters husband has the RS-5 on his bike and I dont really like it too much, and his friend has the Jardine and that seems a little weak to me. But im pretty made up on the Two bros. i like the look and soon i will like the sound. i will probably go ahead and get the pcIII too. thanks for your help and thanks for the link.

Check out my gallery if you'd like to see more pics of the 2bros.... I did modify the mounting a bit. The supplied brackets were too long for my taste so I cut about .75 of an inch off to raise it up closer to the tail. Looks much better IMO. And I painted all of the stainless brackets flat black to blend in... not much of a bling, bling person. I hate chrome anything. I wished my damn rotors weren't so shinny

I ordered the CF M2 exhaust last week; should be here today and will be installed right away.

As far as prices go, shop around, a lot! I know it's the more expensive one. I can't recommend anyone because I work at a bike shop, so I get my stuff at 10% above cost (cuz my boss has gotten cheap), but still cheaper than anywhere else!

10% above cost, damn, must be nice. Don't forget to post pictures of the work when you're finished. Are you doing the install or the shop you work at?

Yes. It came in today and Two bro's made a boo boo. First of all, I have an 06, and the M2 I ordered is for 01-06. WRONG! They sent the wrong mid pipe. So it had to be shipped back and *hopefully* was overnighted with the V.A.L.E. setup (same M2 CF) just different connectoids. I *heard* the regular slip ons had leakage problems?

Yes, going to install it at the shop (love that lift). Pics and vid/aud will follow.

I cant wait to see/hear you video/audio of you 2 bros. I was really looking into ordering it for a self christmas present but havent had teh chance to really hear it for myself....everyone in my town are on damn yammies and gixxers. Only 600RR i seen has DnD and i didnt like it.

Ok here's the deal, straight from Two Bro's.... They are discontinuing their standard slip on's and parts for the standard slip ons and switching to the V.A.L.E. systems only.

Rather than get a midpipe for the 06, I'm returning mine (P/N 005-040407M) and getting the V.A.L.E.... It's a special order part, and will be here in a week I guess. Since my boss doesn't have a dealer account with two bro's, I have to order it through TR. Bummer.

So OP, keep that in mind before ordering the standard slip on-- order the VALE. It's the same cost wise.

Sound clips are here..

Maps for the PC are here

I thought they only made the V.A.L.E. versions now, that's what I got and I ordered mine awhile back. I like how it bolts together instead of using springs.

Yes, I heard that it kicks ass. What do you think of it?

Love it. I little harder to install, I hear, but it was easy for me. I removed all of the plastic off the tail so I could line everything up and was able to tighten it in place. I was worried about it twisting to one side. I'd snug it up then place the tail back on to make sure it looked alright. Then I noticed it hung too low for my taste, so I had to modify the brackets and redo everything. Looks much better than what they intended it to look like.

Here's a couple of pics to get you more excited about yours coming in...

OOOO that looks good! :-)

i think i have decided to buy the two brothers slip on...and was looking online and found some for the 04-05 models...does anyone know if it will fit my 06???

If you have an RR, disregard the below post.

The 2006 F4i's (and I'm sure it's been mentioned many times) need to get the California model exhausts and the reason for that is because of the emissions (O2 module) that is located on the midpipe itself.

If you don't and order an 01-05 exhaust anyway, you will get an exhaust system with the incorrect midpipe that will require you to drill a hole and weld a nut into the pipe to put your O2 sensor in it. Yes, your bike will run without it, but it will A) run like poo poo, and B) you will get incredibley (sp?) crappy gas mileage.

Too much work in my opinion, but hey, to each his own. I just don't know a welder.

Say you're pretty convinced on getting that Two bro's pipe. Great. So go to their website, navigate yourself around and find the list of exhausts for the 06 F4i, standard mount. The High Mount system is not compatible with your bike, but I've known a few ppl on here that have it.

There's quite a few choices. Once you narrow down your list to what you want (or would take), I suggest you start writing down the part numbers and then go on your search on the web for the best price on what you can afford. Make sure you get the V.A.L.E slip on and make sure you clarify when your ordering it that you need it for 06, california emissions (even if you don't live in California) or you will get the wrong midpipe. VERY IMPORTANT-- I've seen this happen many times and those CSR's are idiots.

HTH.

^^ so my 04 600 F4i won't need a CA model exhaust? just wanna make sure before i order one. ive been thinking about micron or two brothers. i know 2 bros have the pop rivets in the muffler...any chance that anyone has had vibrating or rattling problems?? this is really the only factor left in my decision.

Your 04 does not need the 06 california exhaust (Unless your bike is the California model), so you are correct when you order it.


<- edited so many times because my brains are not with it today

Got it and installed it about 1/2 hour ago. Sounds great and got a bit more throttle response. I'm attempting to attach pics (sorry it's dark, I'll get more tomorrow in the light since the flash picked up the tag and rear lights!!)






And the midpipe with the O2 bung. Install was a cinch. Took maybe 20 mins.

Awesome... I heard that Two-Bros are deeper and supposedly louder than the Yoshimuras. Is it true? lol...

I just noticed. You have an o/2 sensor? Is that a cali model? (Who's Daytona is that in the background? That's a sweet bike.)

All the 06's have the O2 in the midpipe- oh wait, you read that, didn't you? ;-) heh heh


Oh, the muffler is hella-loud.

The Triumph is my bf's bike.
