I've never been real excited about the stock exhaust sound, but I'm not real excited about the looks or cost of any of the aftermarket exhausts. My impression is that most of them are a bit loud as well! Not sure how much longer I'm going to keep my 2008 R. Still, I'm thinking about getting the stock exhaust modified by Dean. Any feedback? Enough sound difference to warrant the $$? Since the bike might only be around for another year, any thoughts about an MT-1 helping/hurting resale? Thanks for any input. | ||

i like it. perfect volume & thunder for me. it should not hurt resale value any at all, since it's basically an invisible mod. if you get a bolt-on can you could re-sell it to recover some of the costs and sell the bike bone stock. personally i feel the oem muffler looks good and fits the bike well. the tourque-hammer is another good fit but more $$$ | ||

I'm also interested in any feedback on people who own it. I havent searched (shame on me), but have a few questions too.. Dean, if you have any photos of what you're actually doing to the inside (i read on the website, but pictures are worth a thousand words) i would enjoy seeing them. Lastly, I know it says power and fueling is the same, with an EBR ECM recommended. If you're removing some restriction, is it likely that with the EBR ECM you may actually gain a bit more than with an otherwise stock internal exhaust? Any before and after videos would be fantastic. I'm curious as to how much louder than stock it actually is, and how much quieter than other slip ons available. Unfortunately it wasnt included in American Sport Bike's shootout for the DB numbers. | ||

There was an exhaust 'shoot out', they dyno'd most all the makes. American Sport Bike is your next stop. you can download a spreadsheet with the test results. Bottom Line? Dean and Barker. I pulled the spreadsheet data into MS Access (database) and saved a few queries (sorted various ways) if you want I'll look for it. | ||

Been over every word a couple times... no MT-1 on it. It is a VERY helpful guide, though. | ||

It was never submitted for testing. It's midway between stock and the RT-3 for sound volume, so you can hear it on the highway at speed over the wind noise, but not an overwhelming sound. Little bit of bass sound to it, it's not too loud. The 2 pipes I sent in were essentially prototypes that were not very pretty to look at, but they did perform better than most. The internal mods were well documented when I first did them 5 or 6 years ago, I'll see if I can find the link for it. I opened the top, sectioned out the 2 small outlet pipes, increased the OD for the outlets to 1.75" and buttoned it up. I don't really remove a whole lot, I think the pipes measured 1.125" internally and they looked like the worst restriction in the whole thing. It's a noticeable difference from stock, but like I said, it's not really that loud. The stock pipe is pretty quiet really. This mod will drown out a little bit of the engine clatter at idle. | ||

http://www.badweatherbikers.com/buell/messages/290 431/558532.html That one shows some of the internal pics. It's not the original thread, but it's good enough so you can see what gets done. | ||

There are a few write UPS over on the XB site. I did mine there is really nothing to it. | ||

Thanks Nilla. Good to know there were no regrets. Not worried about the inclusion with the Shoot-out. That seems to me more about the horsepower chase. I want it to look good, sound good, and not hit my wallet too hard. As much as I never thought I'd say this, I've got enough HP for now... My understanding is that I can get the stock ECM reprogrammed and not have to take the EBR ECM hit. (I've gotten cheap lately....) Sounds like I'll be getting in touch with you soon, Dean! | ||

A friend of mine sent his pipe to Dean to have it reworked. I must say it sounded great. It had some bass to it but nothing over the top. This route is the best route for someone looking to get some tone while not having something really loud that will wake the neighbors. | ||

I have the MT-1 on my '09 1125CR and love it. the sound is great, and does not abuse the neighbors, or fellow riders. I've got the EBR race ECM, and KN filter. Bike runs better than stock, more than enough power for me  IMHO you cannot go wrong if you are looking for a pipe that breaths better and does not abuse others with it's sound. B | ||

Count me in on the MT crowd, drove out to Dean's place and hand delivered mine for modification. Love the sound, sounds perfect without being overly loud. I also had mine ceramic coated at the time. Here's the thread I posted a while back about it... http://www.badweatherbikers.com/buell/messages/290 431/736732.html?1398020503 | ||

If i lived anywhere near Dean, I would've already been at his door with my pipe. I'm debating between making sure power with the barkers (and i actually don't mind the look), and the MT1. The cost difference vs horsepower is a given, but i still want to keep peace with the neighbors. Has anyone personally heard a barker's exhaust with the 1" quiet core VS an MT1? | ||
| D_adams |
MT-1 is quieter. | ||

As a reference, having a 96S1 with an empty D&D (loud) compared to the CR with an empty Barkers. First day out with the Barkers the man in blue tells me it was 'kind of loud'. Never had a noise complaint from the cops in almost 2 decades of riding the S1! I bought the medium size silencer. No problems since in last three years and 20Kmi. Part of the problem is the 09+ 1125 race module bike isn't ready for any kind of mild cruising unless you are at or about 3500 rpm's. The S1 will pull you along at 2200 rpm's, big difference. What if you use the stock ECM? You get massive low end and can get away with riding the 09+ bikes at less than 3500 rpm's. Any negatives to that? The electrical system discharges at those RPM's. | ||

I figured this was a given. I was just curious the actual sound level difference or tone between the 1" silenced barker's and yours.
This seems contrary to everything i've read on the EBR ECM. Almost every review i've read on here says the EBR ECM allows you to cruise at low RPMs much smoother than the stock ECM. | ||
| Dannybuell |
You can do it and: - the electrical system will discharge. - your potential for any sort of throttle response on anything but a flat grade will be pretty darn low. | ||

Perceived volume, probably about 1/2 as loud. Low rumble, audible but not pounding you in the face like any open aftermarket pipe, mine included. The MT-1 is a nice balance between quiet stock with rocks in the motor rattling around and too loud to hear the motor at all. It sounds pretty good and you can hear it over the wind noise at speed without killing your ears.
I think the breakpoint for the stator is around 2000 rpm, anything above that should be enough to at least maintain 12 volts DC. I never had any issues with mine in 35k miles unless I ran heated gear to stay warm. When I did, I just kept the rpm up over 3k and left the voltage display up to see that it was maintaining ok. Worst times were when I had both the gloves and jacket liner cranked up all the way and it was 20 degrees out. The battery would discharge down to 11.8 volts in a 30 minute ride with the extra wattage draw from the gear but it was enough to make it home and put it back on the charger for the night. Never left me stranded.
Ahh, no. I've run mine down as low as 2100 rpm in 6th gear with the race ecm. While it's not a rocket at that low of an rpm, it definitely takes off ok. Still making 60+ ft/lbs of torque even that low, so it will get up and go, especially after 2500-2600 rpm. Can't just whack the throttle wide open though, you have to roll into it. Any lower gears, ie; 1st through 4th, nailing it at 3k rpm or above and it would launch mine forward reasonably well. 1st gear would loft the front even that low, once past that, banging through the gears, the front would come up through 4th. My biggest fear was of looping the bike, that's why I don't drag race. Btw, the 1190 is worse with the traction control turned off. | ||
| Cf_z |
If thats your theory, then how do you suppose your battery keeps a charge while idling? 
Great. Thanks! | ||
| Dannybuell |
I respect the 08's for having better systems than 09+ systems. I'm not going to repeat/qualify my statements do a search. A first gear at 2,000 rpm is a clunking and lugging. What we call hills in Oregon midwesterners call mountains, IDK. | ||

Dan, I have a 2008 1125R with my own exhaust system similar to Deans (Adams), with K&N air cleaner and Buell race ECM. I got the ECM when Buell first had them available and tuned by Michael Richter at Buell to my exact system. At first my bike did what yours is doing; clunking & lugging and my idle was set at 1600 rpm. I sent it back to lower the rpm's to about 1300 rpm and my low speed lugging went away. Maybe when they reset the lower idle speed they re-calibrated the low end fueling also. It made a significant difference and since then, way back in 2009, my bike, in first gear, idles cleanly at 1500 & 15 mph and pulls away cleanly if I just roll it on slowly until 2000 before I accelerate. That's pretty much average for all gears, even 6th and I can roll it on from 2000 rpm cleanly going up an 8% grade in 3rd or 4th gear. As a bonus my mirrors do not shake.  Yes it does tend to discharge when idleing along but in these canyons here I rarely ever do that and at home its always on a trickle charger to maintain the original battery now at least 6 years old. Just my take on what has been a great bike. Bob | ||

Got a late start, but received my modified muffler this week. Got surprised by the turnaround time - needed to get a couple new bolts and gaskets fast (and later found out I should have bought clamps as well). The important part is that I got the muffler on tonight and it sounds sweet!!! It was just around the block, and can't wait to go for a real ride. I thought about getting before and after audio, but there wasn't the normal opportunities available this winter. A buddy of mine has a CR that should do for a nice comparison. I'll post clips soon. | ||

My '08 (which has an EBR ECM) will discharge the battery at idle. By default, the EBR ECM turns on the fans at 170F and they don't turn off ever, while the bike is running. The charging system only puts out around 400 watts at peak, and at idle, it's not enough to keep the lights, fans, etc running and have reserve to charge the battery. I did change the fans to come on at 185 and turn off at 180 (as opposed to 170 on and 160 off) and now there are actually times when the fans don't run. In traffic, the fans come on and stay on until I am able to get moving again, but at highway speeds, the bike sometimes cools off below 180F and the fans go silent. And for winter commutes to work, the fans never come on. I also changed the fans from running for 30 seconds or a minute after the bike is shut off to turning off immediately. The last thing a bike with a weak charging system needs is something sucking down the battery even more when it's not charging at all. (Message edited by thefleshrocket on March 16, 2015) | ||

Flesh, there is a parameter in the ECM that shuts the fan off if the key is off and the voltage drops too far, that way you don't get stuck with a dead battery. I've done similar fan temperature mods, my findings were similar to yours, I am happy with the reduced fan runtime. |
