I thought someone powder coated a mid-pipe black. I can't find the picture, but would like to check it out. The shiny stainless midpipe isn't doing it right now for me. | ||

So how do you like the pipe? I know you were concerned about popping on decel; any of that going on? Are you running the stock ECM calibration? A concern for me is how loud the pipe is. I would be driving past my neighbors at 6:50 am, and don't want to be a jackass. Do you think it'll be too loud? | ||

I rec'd a pipe that is blemished and am working with FMF to get it resolved. I don't have the pipe on the bike, but it is high quality. I will give you an assessment from someone that hates loud pipes as soon as I can. | ||

It's pretty loud, much louder than stock. MUCH. Not too bad going down the road, but when you fire that puppy up and let warm, it's WAY louder than stock. I recommend earplugs. I like it. Neighbors will deal with it. I don/t have many, if I lived in town, it might be a problem. I tried the insert, and it seemed to make it louder, atleast more obnoxious, anyways. I had to pull it right back out. There is some decel popping, esp at lower rpm. Above 42 to 4500 rpm, no popping. If you need to be quiet on decel, pull in the clutch. I would recommend it when passing by cops. Still, I love this pipe! I ain't going back to stock, and as long as you run with your inner airbox cover on, and let the ecm adjust for a good 50 miles, I think it runs great, smoother and better top end, that's just butt dyno, so YMMV. | ||

Bigblock, are you stock with your fueling? I can't remember. | ||

Fresnobuell, I think this may be what you were looking for. http://s46.photobucket.com/albums/f141/markeagan19 87/2009%20Buell%201125CR/ | ||

Thanks! I do believe that is it. That header wrap gives me a good idea. Mark, what is you take on the pipe in general? Volume? Quiet insert? Decel popping? OVerall performance? Stock fueling? (Message edited by fresnobuell on October 19, 2009) | ||

Fresnobuell, I love the pipe. Fit and finish is a 10 besides the stainless midpipe. Took me 15 minutes to fit it the first time. Volume is a bit on the loud side but you get a deep powerful tone. I have the quiet core installed with the cone towards the mid-pipe "quietest." I dont know if you saw the videos in that album, but I have no decel popping at all 1000 miles into the pipe. Overall performance, My bike gained a lot of torque at the bottom end. A lot of times I fry the tire from a WFO holeshot. The low speed surge/chatter disappeared as soon as I put the pipe on and is still gone. Believe this or not, but shifting got a lot smoother too. I've noticed that the RPMs don't drop as quickly when you pull in the clutch to shift. It feels like an automatic. I still have the stock fueling. I dont notice the engine running poorly or hot due to a lean mixture. like I said, no popping accel or decel. coolant temp stays at 170. I do plan to put the protune 3 on it next year just for peace of mind though. Don't forget the black "silicone" spray for the wrap. Otherwise it dosn't stay black for long. | ||

I was going to install the cone towards the exhaust exit...hope it's not overwhelming. I am probably going to keep my airbox on. I re-installed it recently and actually like the way it runs with airbox on. Not sure why. Maybe more engineering went into the airbox design than we are give Buell credit for? Plus it keeps the intake noise down, which might be welcome with the FMF... Good writeup. | ||
| R2s |
It might be interesting to order an extra cone and trim it a bit. | ||
| Stlcr09 |
I put my airbox back on too. I'm curious as to what it sounds like with it off now. Maybe I will try it sometime. As for putting the cone in towards the exit of the pipe, I really didnt notice a difference between that and no cone at all. I didn't give it much of a chance though. R2s, Not a bad idea. It may have to be a spring project for me though, This fall has been really wet and cold here in the midwest | ||

ecm tune is (latest?) 2008 CA stock on my bike. Didn't run too good with the IAB off, even after 100 miles, and immediately ran great once I put the IAB back in. MPG up 3. When I put the quiet core (cone facing muff) in, I did not give it time to readjust, it ran immediately worse, I only rode it maybe 10 or 15 miles and pulled it out, it seemed to make the decel popping worse, and didn't sound or run as smooth. SO, I pulled it right out, I'm fine with it like this. Runs smoother and better, esp. down low and at top end, pulls much harder above about 6, esp at 7,000 up, and is a bit softer in the middle. | ||
| Bigblock |
running temp and all that unaffected. | ||

I've had mine on about 500 miles and I get no popping on decell or hot running. My ecu is still stock and I have a K&N with IAB on. The bike sounds mean with this pipe, its super loud but the good kind of loud not obnoxious! | ||

Looks good and should be quieter than my Drummer was before I put some SS screen inside it. I think you'll be OK with the sound Harlan. For your mid-pipe, just go to Lowes and get some black BBQ paint. I keep a couple of cans in the garage for touch-ups. Nice, rich flat black, good to 1800 DF I think. Z | ||

I think a shiny black ceramic coat might be in order. Did you do the BBQ paint on Loretta? Can yo post up a pic? | ||
| Fresnobuell |
Never mind about the pic, Zac. I found it in another thread. Looks good. | ||

Update Today was a nice day so I decided to take the bike out for a ride. After reading Bigblock's comment, I decided to try taking the quiet core completely out. Took me 10 minutes total to do. So here are the observations I made today on a 100 mile ride. The volume is definatly loud now. Crusing at 55-60 I noticed its a little raspier than before but still sounds very deep and powerful. May cause some trouble with small town cops. There is still no decel popping but Im sure the bike hasn't adapted to the change yet Overall performance, HUGE HUGE improvement. If I convinced anyone to use the quiet core, I'm sorry. Throw it away!!! I don't know how big the improvement was over stock, but compaired to the pipe with the quiet core faceing the midpipe, It gained noticable power on the low end (Buy Metzler stock!) Gained even more power in the mid range and gained a huge amount of power up high. Sorry, Im a bit excited. Low speed surge is back to a degree. Not near as bad a stock, but worse than with the quiet core installed. Chatter is not noticable maybe because the pipe is too loud? Shifting and overall ridability of the bike is still butter smooth. Couldn't get any better. The engine still sounds like its running fine. no noticable detonation. I forgot to pay attention to coolant temp but Im sure its still at 170. Hopefully I can put more miles on it fairly soon so I can see if anything changes when the bike "learns" the pipe | ||

To each there own but I love this thing. Sounds good and deep yes its not quiet but it bolts on easily and quickly and the can itself is an awesome looking piece.  | ||
| Fresnobuell |
Photoshop request. Can someone handy with photoshop change the stainless midpipe to black. Please, pretty please. Thanks.  | ||

Just to add to Stlcr09's impression of the core's performance, I agree that with the cone pointing toward the midpipe it robs the top end. With it pointing toward the muffler I think it runs best. Good low end and rev's through the top end, but it needs some time to adjust. Have you guy's been checking the AFV's? | ||
| Xtreme6669 |
on mine the mid pipe isnt that shiny, it matched the headers very well. This pic was the first day installed.. now it matched even better.  (Message edited by xtreme6669 on October 22, 2009) | ||
| Fresnobuell |
The cone doesn't even taper that much. WHo would have thought that it would have such an effect. I will use the cone facing out position first. | ||
| Bigblock |
oh yeah AFV, front was 89.5, rear 100, front moved up to 94.5 now, and rear stayed at 100, about 200 miles or more on the pipe, I haven't checked my mileage in a couple days. | ||
| Fresnobuell |
Mark, THe passes in the video were taken with quiet insert, correct? Did you get any decel popping when you removed the insert? | ||
| Stlcr09 |
Fresnobuell, Yes, the videos were taken with the quiet core. No popping at all after a 100 mile ride. The bike made tons more power but I got some low speed surge back | ||
| Fresnobuell |
Have tried the quiet insert facing out (medium noise?) Man I hope it's not obnoxiously loud without the insert, you have me pumped about the power. | ||
| Xtreme6669 |
not much difference with it in or out as far as noise imo ... runs better with it out thou!  (Message edited by xtreme6669 on October 22, 2009) | ||
| Fresnobuell |
Makes sense....there isn't much restriction with the cone facing out. Guess you can't have your cake and eat it too! I am a little disappointed with the power loss due to the QI. | ||
| Ron_luning |
I picked one of these up from American Sportbike today. Installation was pretty easy. I put it together with the insert cone facing the muffler. It doesn't seem too loud considering it is basically a straight shot. It is quieter than the Two Bros. exhaust I had on my SV650 10 years ago. Honestly it would be difficult to accurately judge power change without a dyno. There aren't any significant changes up or down that I could detect. With the 12Z flash my AFVs were 99.5 both F/R prior to install, after around 25 miles with the pipe on they are now 104.5/99.5 I don't know what color bike you have, but the stainless looks fine on my white model. I could see a black bike looking a little better with a black pipe, but after a few heat cycles the stainless should turn to a more golden color that will somewhat match the stock headers. |
