That is symphonic. Does it sound the same outside the garage?
I like it but I guess some states would have a problem with the removed cat.

Wander what it sounds like just normal riding without twisting it up, i think i could like it, would like to here it with the baffles in the brawlers.

Cops would hear you coming!
They dont bother the loud *** harleys around here, its more the park service that would worry me all the mountains i ride in is considered national forest land and the park rangers around here have radar and like to play traffic cop sometimes, they probably could get you for a slip on without a baffle because the vehicle is suppose to have an approved spark arrestor. I got nabbed by them years ago for treading on their land with a dirt bike, there was a group of us they didnt much care for that lol but they let us off with a good tongue lashing. I think thE baffles would change the pitch and make it a little deeper insteads of high pitched sound thats how they work with just the brawlers any way. Of course in that you tube clip above they was twisting the throttle pretty good insteads of cruising, alot of the time you can tone it down with lower rpm's thats how i used to do my camaro with headers and a 3" straight through muffler, i could drop the rpm's down to 2000 when i was around the poluce and they never bothered me.

Mark

I no longer have the phone that fly by clip was taken from so any chance of an honest over the net sound comparison is out the window but I'll see if I can give an example here of what Akrapovic headers and corked Brawlers sound like. Hope it helps.

What I have and used to do this is a $35.00 Craftsman Decibel Meter. Inexpensive yes but surprisingly accurate and I trust it to be very close if not with-in a 10th as it was in the side by side with the certified +/- 1.5 db. Fluke meter. Also Credit to Jay (he'll troll this I know) a good friend with me who had been bribed with breakfast and pistol range time to cox him out so early setting just off the side of the asphalt writing down what he saw and prepared to be my -Buddy- if need be.

Ambient noise out side was 51.7 db. Nothing but birds, bugs and a breeze.
At idle with meter in hand at chest height setting in the seat 88.9 db.
For the next set of readings the meter was close to 3 ft. off the side of the pavement on a 5 ft. stand, bike in 6th gear on level ground and maintaining steady speed.
50 MPH / 80 KPH 107.1 db.
55 MPH / 88 KPH 108.4 db.
60 MPH / 96 KPH 109.2 db.
70 MPH / 112 KPH 114.2 db. (buddy told me here is where it got loud to him)
90 MPH / 144 KPH 120.2 db.
Full throttle
128 MPH / 205 KPH close to 11000 RPM 5th Gear 131.1 db. :eek: said he could hear me the whole time and I guess it to be a little over 1/3 of a mile or 600 meters as the strip is 3/4 of a mile long and we set up just passed the middle.

159 MPH / 255 KPH again close to 11000 RPM 6th Gear 130 "ish" cause he blinked when I blew by and I wasn't doing it again, had to use part of the drive way to the landing strip to get up to speed and still have room to shut down.

Here is one of the charts I've seen floating around also for an example of how loud things are.

****, that is LOUD! My Ape probably has the loudest stock exhaust on the market and just cracks 100db at full bore. 130 can't be good for ya LOL

I'm wearing 28 db cut ear plugs inside of a RF1200 and its still loud yes. If I were at work I have on over the ear hearing protection on top of the ear plugs at those levels.

Dam Avintage69 im impressed, that was an excellent test you performed there covering every thing from mild to wild, if you got those readings with the inserts in then you have convinced me that it would not be to enjoyable of an experience and my wife definately would be raising he-- if she was on the back, thank you for sharing your results with us that is awsome.

I understand the wife concerns, I actually put my factory cans back on when she's with me. Takes 10 minutes and makes it where we can talk and hear each other. I've been looking for a way to tone it down below the 6 K mark but the exhaust pulse has shredded both attempts.

I know with just brawlers uncorked and no headers the sound is just about right to me, i dont think i would get by in the national forest with the headers also, id probably have every park ranger from Tn to NC trying to pull me over, i could just imagine the sound going through a gorge. But i still like it, if it was just me riding all the time id probably go for it lol, but how the crap do the harley riders get by with it, i guess the higher pitch of a 4 cylinder makes it stand out like a sore thumb when you got it twisted. NC is the only state so far i have seen a trooper giving a harley a good going over after he pulled them over, i really think he was investigating the exhaust.

I've mentioned before that when I take my wife out or and once with my leisurely riding companion's I reinstall the stock cans on the Akrapovic header and am really surprised at the sound. Its a deep tone, but not so loud you cant talk yet loud enough you know its not stock and there is no drone in the low to mid RPM. Just wish they weren't, well so darn fugly.

It's not just about loudness.
With a louder exhaust it looks like you're going much faster then you're really going.
It's just seeking for attention you want to avoid.

If you like to rider harder then legally allowed, and like to do it a lot, the best survival technique would be to be as invisible (unhearable) as possible.
It's the reason I removed my Bi-xenon angel eye mod (too recognizable), and that I'd like to have my exhausts as silent as possible.

I live in a mountain village, and our cops are very different then yours. But I've seen too many cops prepare to invest a biker, when they heard him coming towards them from miles in advance (due to too loud exhaust). Most of the time I saw this they where even off duty ... waiting at a snack bar for their food, but they just couldn't ignore the other people complaining about the sound.
The funny thing is, you hear those loud bikers from way too far, and it gives the cops here roughly 3-5 minutes to prepare themselves. Going to the cop car, getting the radar gun. Putting themselves in position. Fining the biker for a minor speed offence, and fining him big time for every illegal part on his bike.
All this under loud applause of the locals who're fed up with egocentric bikers that cause noise pollution.

Anyway each his thing and his preference.
I'm just saying that it most likely will give you much more attention then you would like to have.

Hmm... I've just inserted the db killers into my G&G Moto2 exhaust and I'm actually enjoying the lesser noise intrusion into my helmet. I believe the beauty of an internal combustion engine lies in the exhaust note it produces. We are inevitably headed toward an electric vehicle future so I'd like to enjoy the aural experience of twisting the throttle because speed is something not unique to an internal combustion engine - you mash the pedal of a Tesla and it will pick up speed... without drama, without any sense of occasion.

Yes, one lives with the reality of increasing noise control regulations and strict enforcement. Yes I have inserted db killers in my exhaust. Yes I need to watch out for and even anticipate a cop ambush... but I'm not into motorcycling just for the speed or for covering miles. I am into it for the sense of occasion, the theatre, the symphony of four pistons at work furiously forcing the gases out the cylinders and into the pipes, the scream of an inline four.

Again, it's a very personal thing and I am not pushing forth my view to others. But this is what gets my heart pumping.
