So I jumped on the FMF group buy with American Sport Bike, and finished the install today. The kit does not come with a quite tip as was shown, but comes with a quite core insert. Looks more like a anti-reversion cone, that slips inside of the inlet of the muffler. I installed the muffler with the quite core, and it's loud but has a nice tuned sound that's not obnoxious. I went for a 60 mile training ride for the ECM and the bike runs very good. Throttle response is as good as stock. I don't feel any more power, but no loss. AFV's F 98 R 95. Now my overall impression, I'm very happy with this muffler. The bike sounds and like a sportbike now. I don't think I would like the sound with out the quite core and I suspect that it might need some tuning, but I'm sure others will have opinions about this. American Sportbike rocks, got the kit in 1 day, but of course we are both in California. Hope this helps | ||

Got mine today, hope to install after work tomorrow, as I just got home... This thing is gorgeous, and weighs nothing, I'm stoked! | ||

You guys are making me want one! Give us a full report please. | ||

Sweet to hear that your happy and that shipping was fast! I also jumped on the group buy and I ordered mine Tuesday evening... I'm in AZ so maybe I'll get it today??!!! Can't wait!! | ||

Also should add that my bike is a 08 with the 05 flash. The kit had good instructions and fit was very good. No real issues. The can is rivet'ed so to repack you need to drill and re-rivet. At speed on the fwy, it sounds very Ducati-ish. Very interested in what others think so mount'em up boys! (Message edited by highlander51 on October 02, 2009) | ||

From looking at it I see only rivets. No screws. I double checked with FMF and they verified this to be correct. Also while I had the tech guy on the phone, we discussed the quite cone and he said that if you turn it so the small end is pointing toward the mid pipe you gain little low end at the expense of top end. I have not tried this but will be interested if some one else does. | ||

tHATS VERY COMMON ON MOTOCROSS PIPES... ALL THE YOSHI AND FMF PIPES ARE LIKE THAT... ITS NOT HARD TO DRILL OUT AND RE-PACK. (sorry for the caps) | ||

Also for those interested, looks like the FMF full system is available now.. http://www.fmfracing.com/Mode/Category/478 | ||

I have the quiet core installed with the small end pointing towards the mid pipe. It does give it quite a bit more power on the low end. I find myself actually frying the tire a lot in 1st  | ||

just finished installing mine about an hour ago, easy as pie. just over an hour and I was in no hurry. this thing weighs nothing, must be a 20 pound weight saving on the bike! It sounds BEAUTIFUL at idle. It looks amazing, SO MUCH BETTER than that ugly stock thing... The CA pipe has a nasty cat right at the end where the headers dump into the muff, it must be a real power killer. I seem to remember, after I had the bike a month or two, they called me in and swapped muffs, I guess it had a 49 state pipe from the factory. It never seemed to run the same after that, I'm hoping this helps a lot! I am waiting until after lunch so the silicone can set some more, then I will ride and give a report. I haven't installed the quiet core, and probably won't. The sound is totally acceptable to me at idle, we'll see in a little while what it's like on the road... | ||

Nice link.... I have never had a pipe with allens in it. | ||

Got mine in the mail and installed today.. went with no quiet insert... Fing loud as hell... I'm going to put it in and see how it dose... the bike feels like the power curve is smoother but has less bottom... I'm only at 326 miles now so i'm babying it a bit so I dont have too much info on power change.     | ||

ya, pretty darn loud. Definitely earplugs, but no louder than my tuber w/ vance and hines, maybe a bit quieter than that. At first, although immediately smoother, poorer throttle response. THis started inproving in about 15 or 20 miles. Decel popping, minimal at below 4200 rpm, haven't noticed any at higher rpm. No quiet core installed, inner airbox removed, no noid. At below 5,000 it will not accept full throttle without a minor intake pop, over 5,000 it seems to take it fine, and pull cleanly. I don't think I haven't tried much over 9,000, and won't until it gets some more miles to adjust, I am at about 70 or 80 on the pipe now. I would say it runs better now crisper and smoother at about 1/3 or 1/2 throttle and less, and seems like it may be equal or slighly less power closer to full throttle. I think the CA map is not rich enough to handle the pipe with the inner airbox pulled, I think Iwill install the box tomorrow, and see what happens. THen I will try the quiet core after that. I suspect a CA bike, atleast an '08, really will need some type of tuning to reach the potential of this pipe. I really like the sound and looks of the pipe, but I doubt any pipe is going to make more power on a CA bike without some fuelling tweaks. I topped my tank off at about 30 or 40 miles after pipe install, 80 miles into my last fill-up, and found 37.5 mpg, about a 3 to 4 mpg increase, it is really too soon to tell, but I suspect a noticeable economy improvement. Did I say smoother? it definitely runs smoother and also runs better in part throttle down low, I am able it seems to run one gear higher in cruise mode now, i.e. I can use 4th where I used to need 3rd gear, etc. Mirrors don't shake quite so bad, either. | ||

definitely runs better with the inner airbox on. Doesn't pop in the intake anymore, but it pulls slightly rough below 4500 or 5000 near wot, esp if you open it too quickly. It revs much cleaner now with IAB installed, and pulls cleanly to atleast 9500 or 10000, haven't tried to spool it past that. THe bike is easier on the ears with the IAB back in, anyways, so even if the pipe just equals the performance of the stock pipe with the IAB removed, I will be extremely happy. I will eventually try the quiet core for comparison, another day perhaps... | ||

Fellas - just a quick note; I've experienced the same 'coughing and farting' hesitation below 5k at large throttle openings (with my HPE exhaust) and solved it by LEANING the AFVs. No kidding. I took it DOWN 10% and the hesitation is gone. Maybe helpful for you guys - maybe not. | ||
| Marcodesade |
I read somewhere that, although leaning the mix will eliminate some of the pop, it does so at the risk of engine damage. I know nothing about whether this is actually true or, if so, why . . . | ||
| T_man |
I know we are talking about two different exhaust systems here but just to be clear; mine wasn't popping on decel, rather falling flat on its face & hesitating majorly. The leaner AFV fixed that. | ||
| Highlander51 |
T-man, do you have any type of restriction like a quiet cone or baffle? Yesterday I swapped the quiet cone around so that the small end faced the midpipe instead of the can. Big difference in throttle response. Flat from 5K up. Although I liked the sound, the bike did not run as well as having the cone turned toward the can. With out the cone at all was way to loud and felt lean from 5K down. I feel that with the quiet core there is just enough back pressure for the bike to run a little better than stock. I stopped by my dealer to show him and the mechanic who works on the 1125's and they were very impressed with the sound and looks. They still have the D&D sitting there at a blow out price but everyone is hip to how loud they are. | ||

I read somewhere that, although leaning the mix will eliminate some of the pop, it does so at the risk of engine damage. Wouldn't leaning the mixture hurt elsewhere, even if it helps decel popping? For some reason, it doesn't seem like good thing to do. | ||
| Highlander51 |
Yeah, I don't think leaning out is the answer on this system. I can't speak of other pipes, but I do think the quiet core pointing toward the can is pretty close. Worth trying, and give it some time to adjust. Maybe i've had to much of the cool-aid, but I'm happy. | ||

I will never decrease my AFV's lower than the learned value - however keep in mind if you disable the o2's then the ECM will work off the fuel map exclusively without the naughty o2 sensory input to f*%K things up. With the o2's disabled - with the stock learned AFV's - the bike is actually running richer due to the ECM pulling the values directly from the fuel map. Hence my 'over rich' condition when I cranked 'er up to 110 with the 02's disabled. So much to learn and that makes it half the fun! | ||

for this pipe is the slip on all u need does that include the mid pipe | ||
| Xtreme6669 |
the mid pipe is included... | ||

Should be getting the FMF on the 6th. Now if I can just get the clutch weep (spit) fixed, we'll be ready for more fun. C. | ||

Went on a spirited ride for about 180 miles in the twisties of Southern Ohio this weekend and averaged 37mpg with the FMF and the Jardine Protune. Gas mileage increased by about 3-4mpg over the stock exhaust. |
