Remus Hexacones Baffles In or Out??

[Wicked Webby]

Hey to all you FJR rollers,

My Brother has a 06 A that we just installed(no problems) the Hexacones on with the baffles in. My 07 A has the baffles out. It should be noted that the baffles don't appear to be very restrictive. Noise wise between them in or out isn't as much of a difference as you would think. The actual noise level (how loud) doesn't change all that much BUT with the baffles in the bike sounds a lot more crisp or pitchy and not as much resonating on decel. With them out the bike sounds more throaty with a bit more resonation. Witnesses to our noise demo(group of car mechanics that work for my Brother) actually liked the sound with the baffles in.. Personal preference is key here. I like the sound better too with baffles in.

Well, we did a endless amount of different gear roll-ons to see how the bikes compare side by side (the 06 baffles in and the 07 baffles out).

It should be noted that my 07 has about 6000mi and my Brothers 06 has 600mi(yes he doesn't ride enough). We bought them both at the same time this past May(his was a hold over). My 07 had about 3/4 tank of gas and my Brothers had about a 1/4 tank full. However, I weigh about 215 and my brother is about 225.. So I was guessing that the weight was pretty even between both rides. How much does a half a tank of gas weigh??

Here is how it stacked up:

1st gear(around 5 grand)..... Way too Even.. too close to call........

2nd gear(around 5 grand).... Way too Even.. too close to call........

3rd gear(around 5 grand).... Even.... though right before red line the 07(baffles out) pulls ahead a wee bit prior to shifting.

4th gear(around 5 grand).... The 06(baffles in)pulls ahead about 3/4 a bike length initially but the 07(baffles out) reals it in near red line.

5th gear(around 5 grand)..... The 06(baffles in)impressively pulls ahead about 1 1/2 bike lengths initially and then the 07(baffles out)starts to pace and

slowly reels it in and passes(a slow pass) it sometime around 8 grand heading for warp speed.

5th gear(around 4 grand)..... The 06(baffles in)very impressively walks away about 2 1/2 good bike lengths before the 07(baffles out) starts to pace it and,

again, begins to reel it in and passes(not as slow of a pass this time) it after 8 grand hitting warp speed.

Interestingly enough.. My Brother was saying that after the 07(baffles out) would pass him in 4th or 5th it would seem to only get a head a bike length or two and then the 06(baffles in)would seem to pace its clip. But we did not attempt any top end speed runs.

We both agreed that with baffles out the FJR seem to have a better top end(More HP on top) BUT was this due to the baffles or because my Brothers 06 isn't broke in yet? Though with the baffles in better low end(more low end torque).

We were very careful not to try and get jumps on each other and be very fair because we truly were trying to decide which way to run um(baffles in or out).

Though, we both agree that we like the look of the pipes with the baffles out better.

One other tid bit...My Brother owns his own Automotive business(a lot of tools and mechanics ect ect ect). Well right after we parked he grabbed his infrared heat tester and checked temps of the header on all four cylinders on both bikes. The 07 with the baffles out had a significantly cooler header temp on all 4 cylinders.... like 35 degrees cooler. Remember both bikes just finished competing side by side. Obviously with the baffles out, it was more free flowing BUT maybe TOO much with no power commander? Also we were speculating that the more heat (I know heat is bad) may have been from more torque/Hp building quicker if indeed the 06 was weaker on top because of not being totally broke in yet.?.?.?

One other heat check..He tested our rear pumpkins(in the same spot)...His 06 still has the factory gear lube, my 07 has Lucas full synthetic gear lube...Drum roll please,..,,.,.,.,.,.,., mine with the full synthetic gear lube was 10 degrees cooler than his.

Those of you with the Hexacones which way do you run um? What I am contemplating is this... I know my Brothers motor isn't even broke in yet so that could easily describe my 07 having the advantage on top...and maybe .. the better performance set up for the FJR with the hexacones is to have the baffles in????

Do either of you have a PC-III configured for the slip-ons (baffles removed affect back-pressure even further)?

Should make a difference in performance and sound I would imagine.

HtRJ thanks for your input,

Nope. Neither have the power commanders installed. Won't do them unless we put on the full systems (holeshot headers also).

We have no FI reasons now to have to add that mod..Both bikes run good both ways(baffles in or out). I bet you are right though.

They will probably perform better with the baffles in until the custom tuning comes with a power commander. Then the baffles out

would be the way to go plus the full header too!! Just what I am thinking?? It is amazing the difference in low end

grunt with the baffles in vs the being out.

Fuel weighs around 6#/gallon, so about 20 lbs for 1/2 tank; basically even. And 8K rpm on 5th is basically topping the FJR out. In fact, at my 4K' altitude, I doubt mine will pull that much, but can't find out until it rolls to 1K miles.

More than the 600-mile engine not being fully broken in, which is true, I wonder if both bikes had the windscreens all the way down, both riders either tucked in or not, both bags or not, etc. At 130mph+ any extra drag makes a bigger difference than the engine being broken in or not IMO.

Don't know how the baffles attach to those pipes, but if they could be cut some for the hex to show like with no baffles, it'd be great. Yes, the baffles look bad, but not nearly as the ugly springs :lol: . When you defended the springs on a prior post of mine in a mad tone, I knew you were going to get those pipes; typical 'Harleyesque' reaction . Later.

JC,

We both had our bags on... Screens down and both tucked.. However.... I have the stock shield and my brother has the larger Yamaha touring shield...Good point on mentioning the shields!! Thanks for bringing that up, I forgot to mention it. It definitely comes into play and re-affirms my idea that the baffles in(for this setup)is the better performing option.

FYI, Ease up man...I wasn't mad at you on any previous thread. HOWEVER.... I have owned a lot of street bikes and track bikes. I have never owned a pipe(on any import bike) that did not have these springs(including: Erion Racing, Graves, Akrapovic, Two Brothers, Arata, Devil, Leo Vince, Arrow, Remus). In fact, the only pipes that I have ever had that didn't have them were for the Harleys.

I found it funny that you would pick out something(that the majority of all expensive performance exhausts have in-common) like that to complain about.

BUT hey to each his own on likes and dislikes.

If my balls ached after a tease here and there on this forum(at times deserved), I would probably quit being a member(like others have done..Some have even run out and bought C14's too).

Thanks for input on this thread.. I totally forgot to mention the shields!

What kind of reaction was this?

HA HA HE HE HE HA HA :lol: :lol: :lol:

I read this on the internet - take the springs off and you will get 2-5 more hp. Honest.

 

[Wicked Webby]

MGM,

Ya, I suppose with the springs off and baffles out you lose a good 3 grams.... HMMMMMMM

HAhhaaha HA

Just installed my Remus Hexacone.

I have the baffles in, with the Holeshot/Wally map on my PCIII. I do have a 5 in the zero throttle position from 0-5000 rpms.

I have them in by default. I could not get them out. Removed the hex bolt but couldn't pull them out. I gave up as soon as sweat was dripping off my forehead.

However, I will be taking them out - or at least giving it another try. I do not find them loud enough with them in (or my expectations should be changed).

I'll ride with this set-up for a week so I can feel the bike with the PCIII map and the mufflers. Then try next weekend to remove the baffles.

Overall the Remus is "nice" but those springs were a ***** to put on and there is nothing in the instructions about removing the baffles. Maybe I just don't have enough motorcycle muffler installation experience to "know" what to do. *shrug*

Heh....

I was at dinner the other night with some friends... and they wanted to hear the sound with the baffles out. So i took out the screws and tried to pull them out... no luck. Eventually I found out that by putting my index finger into the baffle and pulling on it's inside towards the back, that I could get them out. Make sure they're totally cooled off before you try this though.

I find them a bit louder without the baffles, but not obnoxiously so. Haven't decided if I'm going to leave them in or out, or what map I'll eventually wind up running.
