two brothers exhaust
« on: August 13, 2014, 08:54:09 pm »
I would like the BLACK Two Brothers slip on for my 2012. But my dealer says I must put in a Power Commander at a cost of about $500 parts and labor. (Sure they want the work.)
The Two Brothers site says I don't need to do that , although it is desirable. (Sure they want to sell an exhaust)
I don't care if I have 5 more or 5 less HP.  Just want a good sound. I DO NOT WANT TO DAMAGE THE BIKE.
WHO DO I BELIEVE??????

Also what should I pay for the exhaust itself?  Who is best on line source?

I've been running a Two brothers black series for a year and a half with no issues and no power commander.

you might get a little bit of dedel popping.  I get that with mine and a cs.1.  Nothing to worry about though.

I just installed mine this AM. I have the ECU flash from 2 wheel dynoworks. Nel's wants to put it on the dyno and tweak it if necessary.

I really like the sound of the CS1. Mellow and not loud at all. perfect! But how to gid rid of the sputtering at the header midpipe joint?

I see a metal ring gasket on the stock pipe. Instructions did not say to use this part for a better seal.

Guess I am going to pull it off and see if I can get that gasket to fix the sputtering.

Run away from that dealer and never look back! I have over 10k miles on a TBR Carbon black slip-on and am very happy with it. No need for any additional installations or equipment either.

I had to use the aluminized exhaust repair tape and Inferno metal repair paste to seal up the leaks at both ends of the midpipe of my CS One. Otherwise the noxious exhaust fumes were just too much for me and my wife. Now I have no leaks, no fumes and it sounds great.  :)

I have the Muzzy slip on with no fuel management and no problems after 58,000 miles.  The deceleration popping can be cured by plugging a tube coming from the air cleaner box.  Search decel pop or some variation of that on the site and you'll find pictures and instructions.  I don't mind it myself and if I hold the throttle open very slightly while decelerating it doesn't happen.

Ok, I was able to cure the sputtering at the header, still get some blow-by at the mid-pipe. I will try some metal tape used for furnaces.  :beerchug:

Put a Two Brothers carbon fiber black series on my '12, looks better than the potato launcher and about 12 lbs of weight gone.
Did not do put on a PC, runs no problems at all, does pop some on decel but nothing bad, more pronounced  coming off of high rpms.
Got mine here, best price I could find.

Thinking about doing the Guhl ECU flash over the Winter, so it also does something with the secondary flys, as opposed to just removing them.

Sorry bro, but...




FWIW, the C14 comes out of box at 133... So my only guess is whoever is doing yer dyno work has a dude behind the curtain doing funny business.  ???

Now that's an interesting topic. When I bought my 2013, the dealer told me that the HP at the crank was 156. I've only seen rear wheel HP figures in the motorcycle mags. Kawi doesn't publish anything on their web site that I've been able to find.

I trust this guy and I'm standing there watching. My disappointment was the stock HP :-\, I read a report when I was shopping for buying the C14 that the stock HP was out of the box 139HP, I assure you there was that much change :)

I'm not experienced with it, but as I understand, there can be variation between dyno machines.   from the sounds of the stock numbers, that could be the explanation there.  As to the "after" numbers, I've not heard of gains like that, but have no expertise to refute it either.

Perhaps someone with some experience will chime in with how these things are calibrated and trusted.

Okay you say it makes 133 out of the box, his was down a bit, 5-hp that's certainly within a normal range, and then with a pipe and PCV it went to 142, what is so unbelievable about that. It is totally within a reasonable expectation. 14 hp with a pipe and a tune, you're talking 11%
