I see the myth statement above..."loud pipes save lives"... Seems there is still some/many that don't know much about how sound works...! While unfortunately my HMF slipon is a bit loud (though it does sound good..), I'm taking steps to try to quiet it down...for my neighbors sake. I leave home at 5:30am everyday for work.. Mike | ||

I see nothing wrong with that. I'll NEVER chastise anyone for being considerate. | ||

I think it's got a reputation. It's not really all that bad. I think you're crazy. I do NOT terrorize my neighborhood, and I will wait in grocery parking lots for children and people to walk by and away until I crank it up and move under an easy throttle. The only time I abuse that throttle is in the twisties, track and when I need to get someone's attention. Let me put it this way. I'm a motorcycle and general gear head enthusiast. I LIKE good sounding and noisy motors. If you lived in my neighborhood and just IDLED past my house with an 1125 Drummer, I wouldn't like it. And after enough times, I probalby would say something to you about it. That's how loud this pipe is. For everyone that thinks "It's not that bad" or "I stay off the throttle early in the morning through my neighborhood" are living in a pipe dream. This pipe was louder than my ironhead Sportster with straight drag pipes on it. I have a buddy who used to have an XB with the D&D on it - when he heard the Drummer, his only response was "holy f***". This pipe has a reputation because it deserves it. Period. And driving a Top Fuel car down the street under easy throttle is not being considerate. | ||

Just the part about the top Top Fuel car though.... R | ||

I'm curious; do we have Db ratings for all the popular manufactured 1125 exhausts? Maybe we could determine a baseline Db rating for how loud is 'too loud'? | ||
| Jdugger |
Sound Pressure Level (db) ratings may not tell the whole story, either. A couple of reasons: 1. Generally, measurements are taken using the dbA scale. This is a scale developed which (very) roughly takes into account the human hearing's preference for midrange vs. lower frequency information. So, for example, it's possible for an exhaust which produces enormous amounts of low frequency information but relatively less mid-range to score "lower", even though it's technically producing more sound energy. 2. Midrange sound is relatively easily blocked by walls, bricks, etc. Bass information, while it doesn't travel as far, does tend to more readily travel through even surprisingly massive structures. So, again, a pipe that didn't measure "that loud", perhaps even on a flat db scale, could be perceptively more irritating in a dense neighborhood. It really comes down to just being polite. My track bike has stock exhaust because I load it under power into the truck. I live in a very dense neighborhood in downtown Dallas. Even stock, it's so loud that I try to load and get it turned off as quickly as possible. Get into a street with 40ft brick buildings on both sides of a 20-ft service way, and it's like an echo chamber when you start a bike. | ||

T_man - I read rumor of Al at American Sport Bike doing an 1125 exhaust shootout similar to the XB shootout. I don't know if it was just speculation or fact, but that would give us all the info we're all after - sound, noise, power, etc. It helped me a ton in decided on my XB pipe. | ||

OK, so I was raised Catholic... guilt, you know. Anyway, today I was playing in the garage and I stuck some stainless screen I've had for 30 years, inside the Drummer, from the front. The length of the can, about a foot and a half, rolled up. Standing next to it idling, I can hear the valves again. It still has an healthy growl but is much muffled. Went over to Dan Dunn's after that and got a dyno run. For comparison, with the 03z ECM flash on 05JAN08 at 40* F, stock can and A/C on the same dyno, I got a best of3 run of 125.4HP Today, at 87* F, a modified 05Z flash, K&N and Drummer - 121.4HP, 68 Ft-Lb and a 12.4:1 A/F ratio. <edit> oh yeah, I came home and leaned her out a bit, shooting for 13.8. I didn't wear ear pods for the dyno run either. Zack (Message edited by zac4mac on September 11, 2009) | ||

Did you make any runs without the choker shoved in the pipe? | ||
| Zac4mac |
No I didn't. I've been trying to get a dyno run(read FREE) for a while and was happy Dan squeaked me in. I put Loretta back together in the parking lot as he was locking up. I also found a "tailpipe extension" that slides in smooth and tight. I can't run with it because it sticks way out, but for starting early or doing running tests/checks, it knocks the sound down even more. I now have a "neighbor friendly" Drummer and I'm still tickled with the sound. I'm not looking for every extra HP I can get, Loretta's got enough power to scare me now and then. All I've ever wanted is to hear the exhaust a little and have a smooth, strong powerplant. She has plenty of low end grunt and when I'm in town, I short-shift a lot. I putt thru the neighborhood at 1600 rpm in 2nd with no issues. She's like an XB with an extra 3000 rpm on top. Nirvana. Z | ||

It's not really all that bad. Unless you are parked next to a wall, or in a garage. Then, it's loud. Really loud. So just pretend that wall is a car or person next to you....you guys say you care, but you you really? Irresponsible and selfish. Plain and simple. Thanks much in advance fore f'ing it us for the rest of us.  | ||

Zac, My neighbor behind me is probably in her late sixties and loves the sound of my 79 Malibu that thumps pretty good and she also likes the Drummer  . I can't wait to see what people say at Mid-Ohio about the pipe! Every time I have been there with the stock pipe my bike is always drowned out by the I4 bikes. It won't know. I love my Drummer. | ||
| D_adams |
I am SOOOOO ready to fabricate my own exhaust now... getting a Miller tig welder next week. | ||
| Teach |
I am hoping that there will be an exhaust shoot out. The last one was very informative and it will be interesting to see how the aftermarket stuff performs compared to the stock exhaust.  | ||

Ear plugs required to ride ANY motorbike?! Get real. Never needed, or wanted, any such thing -- and I ride a LOT (600 km weekly) -- including on track days. | ||
| Xl1200r |
Zac - good for you. I think my baffled Drummer sounds just as good as unbaffled, just more enjoyable for me, and I'm betting everyone else. Ear plugs required to ride ANY motorbike?! Get real. Never needed, or wanted, any such thing -- and I ride a LOT (600 km weekly) -- including on track days. Red, you need to get over yourself. 600km weekly is formidable, but nowhere near "a LOT". Try doing twice that, or more, in a single day. I don't wear earplugs everytime, but on long trips it makes things MUCH more comfortable - and this is more for the wind noise than the ehaust. | ||

I always wear ear plugs. Not so much for the exhaust note but the wind noise. Wearing ear plugs not only makes the ride more pleasant, but makes it easier to hear the stuff u need to hear, like car horns or emergency vehicle sirens. | ||
| Fresnobuell |
+1 on the ear plugs. With a "normal" exhuast wind noise is far more damaging than exhaust noise. Slowly but surely all of my riding buddies have migrated to ear plugs. I rode 1 hour on the freeway without plugs recently and it was amazing how muted sounds were when we stopped. | ||
| Badlionsfan |
If I get down the street without putting them in, I pull over and put them in. | ||

Guys, with all due respect, but you can have a "loud" muffler/system that can be quieted some to "nice" unoffensive levels and keep performance. Please read the threads that have been posted on quieting/reducing noise posted by myself and others. I really like a nice throaty sound on cars and bikes. Open header loudness is for the track only. I can hear "Slick" coming on every turn or straight even on the TV. I AM old but I'm not stupid. Bob |
