Loud Pipes (When Lane Splitting In California)

I work part time at a Harley dealership and loud pipes are one of the first changes everbody wants to make. Seeing as what direction a noise is coming from is not always readily apparent, I really don't buy into the argument that loud pipes save lives. I, myself have already been sitting at a traffic light in my car when I heard an ambulance or police siren coming and had to look around to see just what direction it was coming from. If loud pipes were going to do you any good from a safety standpoint, it would be imperitive the cage driver be able to instanly recognize your position in relation to them. I don't believe this is likely to be the case. That being said, i restate what others have already posted. Wear bright colors, use extra lighting, install a louder horn, and most important, practice safe riding tecniques to avoid being in a dangerous position.

 
I will go against the grain here. Riding in the city with lots of lane splitting it is very helpful to have pipe's that are louder than stock, not open Harley loud pipes but some that do have a rumble sure are nice while lane splitting. I never liked lane splitting on the FJR because no one could hear me but when I rode my FZ6 or FZ1 and now my KTM with aftermarket pipes lane splitting was so much easier and safer IMHO.

Nothing wrong with making some noise. There are plenty on this forum who run aftermarket pipes that are louder than stock-you know who you are.
Yep. You got me, Doug. As you know, I'm running a Muzzy 4-2-1 with Muzzy's "Quiet Core" muffler for the weight reduction and to take advantage of valve overlap on a 4 cylinder motor to squeeze a few more HP out of it. It is louder than the OEM exhaust, but it sure isn't close to the dB levels of an unmuffled FJR or V-twin. In the 5.5 years it's been on the bike, I've seen no safety effect from its sound levels. Two reasons come to mind.

First, I don't split lanes at high enough rpms to be significantly louder than OEM pipes. I just don't see any reason to split slow traffic with the engine in the higher horsepower rev ranges where aftermarket cans make any real noise.

BTW, have you ever been in your car when an unmuffled V-twin splits lanes by you? Last time for me was only a few weeks back, and I had no idea he was there UNTIL he was passing me. (I do look for motorcycles and give them courtesy space if I see them lane sharing, but I just didn't see this guy, maybe because he was moving significantly faster than the cage traffic I was stuck in on I-80.) The deafening roar with the flash of his movement to my right startled me the same as a jet crashing on the freeway might have. What it did not do was have any warning effect to alert me of his presence in time to give him space or avoid him.

So second point, as others have pointed out: ahead of the moving motorcycle closing on a slower or stopped car from behind (especially between lanes of cars), a driver won't hear the exhaust noise until the bike is on top of him or past him.

Sorry, but I'm sick of unmuffled pipes that don't save lives deafening anyone who is trying to have a conversation when the nuisance rolls by -- of having to wait until the bike is out of range before resuming the conversation that was rudely interrupted. I'm pretty sure most citizens feel much the same.

I could echo the sentiments of many here and give you a ration of crap for suggesting that making a motorcycle louder would somehow make it safer to ride in traffic, but since you've changed your mind, I'll save my crap slinging for Bug.

I've had good success with fork mounted Clearwater lights (Glendas) that Sac Mike alluded to https://clearwaterlights.com/infopg_glenda.html and a good set of hi/low horns with a upgraded horn wiring harness from FJRandy have served me well. Good luck with the mods. https://www.fjrforum.com/forum//index.php/topic/107893-fjrandys-plug-n-play-horn-harness-update/page-3

BTW, the hooligan looking driving lights are Solteks Fuegos, not for the timid or weak (mirror mounts that is)!

OK people read my lips in bold. There is a difference between a nice soft growl such as Stainintunes and the abnoxious harley straight pipes. The op lives and commutes in LA so one must assume he does his share of lane splitting and such. Nothing nicer than having a nice little growl that a quick blip on the throttle helps people hear you working your way through traffic. I love the Akrapovic (with db killers) on my Katoom and after 200 miles today watching animals in pastures reacting to some noise while we were riding those twisty back roads you can't tell me sound does not travel ahead. Same in freeway traffic as I have heard bikes lane splitting before they get to my cage in traffic back ups.

I have no problem adding a little noise to the arsonal of devices/techiniques for a safer ride while hearing the sweet sound of motorcycle horsepower.

"You know who you are" Rich, I wanted to see of you were with us today

Lane splitting is a different animal. With different needs for riders.

Found that out on recent trip up US1, San Diego to San Fran.

It's Very Common for riders to be revving the bike to be heard. At the slower speeds for splitting, you can hear them coming from behind. It helps.

My Versys has stock exhaust, but also headlight modulators and Piaa horns. I didn't feel a need to have louder exhaust.

 
I love that "Loud pipes save lives" argument. One more point.....

If the loud pipes are for your own safety, why aren't you wearing a helmet? And why are you in a bar drinking beer, then getting (helmetless) on your bike?

I don't give a crap what you do with your own life, but don't give me bogus reasons for your selfish, obnoxious (loud pipes, I mean) behavior.

(By the way, this wasn't aimed at the OP, I'm just venting about the d-bags who have loud pipes "for safety", and want to tell me all about it).

No dispute on that, but due to the difficulty in expecting LEOs to enforce dB denominated prohibitions on the road, the legislative trend in reacting to pissed off citizen complaints about loud motorcyclists is to simply ban all aftermarket exhaust components. It's a LOT easier to just have the cop write a ticket for having replaced your mufflers. So . . .

That means that if you damage an OEM muffler, you gotta bend over and pay the astronomical price of replacing OEM with OEM, since a less expensive aftermarket can won't be permitted AT ALL. Similarly, you'll have to give up what you find to be the pleasant (while not excessively loud) growl that aftermarket cans provide. And you will no longer be able to take advantage of the HP boosting and weight saving benefits of a true header system that is available only in an aftermarket system. Why? Because some assholes need to make their bikes so loud that it makes most citizens wince. That's just about "lifestyle" and ego (though I've heard from some women that it can also reflect inadequately small bedroom equipment), and not about saving lives. Unfortunately, for too many citizens who complain to legislators' offices, they lump all of us who ride motorcycles into the perceived group of obnoxious and selfish offenders.

The op lives and commutes in LA so one must assume he does his share of lane splitting and such.
I believe that he said, in his crash thread, that he lives at 4,000 feet and commutes the Grapevine, so I'm guessing he lives out in the Frazier Park vicinity somewhere -- nicer and much more rural than L.A. urban living, but still has to deal with the traffic of L.A. to get to work. That would also fit with the comment he made about dirt riders trespassing.

You do know that most of us were concerned about just what you would learn from Bust when you two rode together in September? Alas, it appears that his sheep whispering and livestock calling has rubbed off on you. Just because Bust told you that when livestock hear the rumble of your Katoom, it makes them want you doesn't make it so. You're projecting to the sheep a reaction that you want to see -- just like your sheep whisperer mentor suggested.

EDIT: **** this new software, slappy was right about the direction the software is going. It's just not worth the time investments or elaborate editing keystrokes needed to try to post or to fix what it did to what I posted when the editing function is fucked beyond all recognition and it loses what is posted. Insert a string of Warchild worthy expletives here, please!!!

loud pipes only make those around you (including other riders) think you are an obnoxious scumbag (quoting wfooshee).

 
This topic has gone NEPRT for good reason.... but no one said that WE LIKE LOUD PIPES on our own bike, but not on other bikes.

I know some of us are more 'mature' than others, but even I like to 'hear the bike sing' a little more than a tranny whine. I like to sweep a corner after down shifting and feel a little like an AMA pro.

Clearly, the rider doesn't hear the noise, so no real safety issue is gained. (Just pissing off those you passed by.) But that growl in the rear makes us feel faster than a stock pipe. Still, I keep riding my stock pipe (and after market horns) and TRY to act mature.

 
All Rich's talk about rubbing off is making me randy... And no way did I "rub off" on Dougie, I was busy railing away on livestock.

However I suspect he may have rubbed one out on me as me arse was stuck to Luci's seat sometime later..

From what I have seen, loud pipes do not save lives. I do not need to hear the guy blow a shift 3 blocks away. They do, however make me want to brushup on my sniper skills after the third time the baby has been woke up.

On the other hand, they do actually help stop making some cagers mad... sometimes. This is because, when passing or splitting a lane, they hear you comeing up and are not surprised/startled then angered.

These seem to be a great compromise, loud when you want it, quiet when you don't. I like the automatic feature, after all, if I am revving it beyond 5000 RPM, for longer than the second it takes to open, I am not in a neighborhood where quiet is valued. OTOH, jerks could leave them open all the time.

I just don't see spending 1300.00 bucks for the system.

I leave Silver stock. For some reason, I like hearing the primary reduction gears whineing away as I cruise along.

My dream system would have a fairly large common chamber, one really quiet muffler on one side and on the other side a can that looks exactly like the first but would have a fast acting (solenoid pull) cutout feeding an actual, mathematicly correct trumpet bell inside the can to maximize low pressure back pulses. Instant LOUD, instant quiet.

And that's the counter point to those who want to justify it as a safety issue. It's as you pass. By that time it's already too late; you're past them. Being alert. Being skilled. Anticipating possibilities. These are how to manage risk. Loud pipe lose rights.

 
Would someone explain how a very load noise behind you, will allert someone ahead of you? I do not get it?

This topic has been misunderstood. The OP mentioned loud pipes when LANE SPLITTING in California.

Have you ever done that? I have. Yes, they are going slow enough that loud pipes can be heard ahead of them.

I sure have, yes.

And claim that loud pipes are effective for people in front at any speed is a bit dubious in my opinion, and FAR outweighed by annoying people that probably weren't too happy about somebody lane sharing to begin with. I hope loud pipe folks don't screw up lane sharing for others. :)

Look back at what the OP said... he was talking about a "cut off valve" and other things that would allow to "turn on the loud" when needed, and turn it off when not needed...

Don't think anyone here (especially!) would disagree... loud "I'm a moron" pipes are idiotic. But when Lane Splitting? I did it and could live with my stock pipes, but I can tell anyone that hasn't done it, if u did this regularly you'd realize that some cagers hate the fact you can filter to the front, and intentionally try to block you from doing it.

The OP mentioned the (on / off) loud pipes so they could scare the cage into thinking they were some "bad ass biker"... honestly, having been there, I can understand that. Even though it's legal, many cagers could care less.

 
Let me start by saying I LOVE LANE SHARING...........any time you want some lessons let me know ........

and **** the loud pipes what you need is lights.....the cages can see your lights but can't hear your pipes over their stereos.....
