Loud pipes save lives?

[go cytocis]

The problem with that study is that is covers "aftermarket mods"...just because they had an aftermarket exhaust, that means that is what caused the accident? Don't think so.

I don't think so either, nor do the authors of the Hurt Report who make no claim that that there's a causal relationship between loud pipes & collisions, just a positive correlation.

There could be many reasons for this: Riders of modified bikes ride "harder"? (as you suggest) Probably. Riders with loud pipes have a false sense of security? Maybe. Loud riders are more annoying & incite more road rage against them? Perhaps. Riders with less skill tend to compensate with more mods? Who knows.

Regardless of the cause, the fact remains that if you've got loud pipes you're statistically more likely to be killed or injured in a multi-vehicle collision, period, no matter what the folklore says.

loud pipes and bright lights save lives.

i commute to work every day so i see what effect my 94db pipes have on cagers, also run driving lights, 12v 55W halogens, yes they are kitchen down lights i modified and waterproofed.

here's a pic

My loud pipes have definitely saved me before. A mom in a minivan almost merged into me last summer when I was on my supermoto. My reflex wasn't to hit the horn. I quickly pulled the clutch and cracked the throttle to rev limiter. Scared her so bad she almost ran off the road in the opposite direction.

So, by your own account, it nearly caused death.

riding down the road on my KLX400R witha full yosh system (really loud) i was slowly passing a soccer mom in a mini van, windows up and as the rear of my bike passes her on her left with my pipe basically right in her face at 5,000 rpm i catch a glimpse of the mini van bumper coming into my lane right at the rear of my bike. i switch to 4th and grab a fish full of throttle. as i pull i way i hear the tires squealing and look back to see soccer mom in a full out panic maneuver.

adding a 100 watt 8" race light seemed to help me get better noticed.... on the street, not so much by big ass duallies in parking lots tho

I also can say the noise helped make drivers alert when they dont see me .its not cruising and being loud, its the dropping a gear a revving it up that catch their attention.

I just like being loud and obnoxious!

I just like being loud

See, here's a guy willing to just tell the truth!

Don't get me wrong, in appropriate places (read: at the track, at meets, or in rural areas), I love loud pipes as much as anyone. I've got an R75/5 with a pair of Hoske megaphones that makes most straight-pipe Harleys sound cute.

I'm aware however that most of the general public doesn't share my aural appreciation of an Airhead flat twin at anti-social volumes so I keep it out of their ears. And certainly when it comes to safety, I'm under no illusion that my exhaust is playing any role in keeping me out of a collision with a car.

But hey, it's your life, safeguard it with whatever myths & old wives' tales you like. Just know that the research doesn't support your beliefs, & understand that you're harming the image of the motorcycling community amongst law makers & the general public.

Lighting? Definitely! Research bears that one out & it's why bikes come with daytime running lights. The pipe however? I'm still skeptical.

Since we're comparing annecdotes on the subject, I had a little KLX250sf with a TBR M7 pipe on it which measured 105 dB! (My XB with Drummer 'only' measured 96 dB). But because the KLX was small & black, it was forever getting caught in cager's blind spots. While it was LOUD, it was one of the most dangerous bikes in traffic I've ever owned simply because it was visually inconspicuous.

In my delusional opinion loud pipes help in slow, very slow speed situations with an alert rider. (parking lots, garages, cruising for women) But anything that increases your visibility is a much better investment in your personal safety, but not so much with the ladies.

Well my Drummer has increased the size of my Knob incredibly!!

Bright lights may be good for frontal veiw, but the drivers on the interstate that come from behind, or side dont seem them.
+1 on the brighter visibility clothes.
And there are the drivers out there that just dont see or hear the bikes

Anything you can do to make your motorcycle better seen/heard/acknowledged the better.

From the above link:

After reading through every single motorcycle accident report I could find I had to admit that not one of them drew any sort of definitive correlation between a motorcycle's noise level and the likelihood of its being in an accident. The closest thing I found on the subject was in the "Hurt Report," which determined that modified motorcycles were overrepresented in the accident column and that large touring bikes like Gold Wings were underrepresented.

The problem is that it's easy to read more into those statistics than the author intended. Granted, choppers and cafe racers (and now some sportbikes) often run loud pipes, but extrapolating that into something further than a few general comments on why they may be involved in more accidents than any bone-stock bike is foolish and, yes, a little irresponsible.

The Hurt Report was about modified motorcycles in general. Comparing a mature person who only puts louder pipes on their bikes to some testosterone-fueled young'in that has added a cage, intake, exhaust, hi-comp pistons, etc., and saying they're just as likely to wreck is ridiculous.

I'd like to see a study specifically aimed at loud pipes vs accidents.

Kind of like people complaining about lane-splitting being dangerous, but then someone did an official study only to find out that it is indeed safer for everyone.

LMFAO good one go cytocis! how did you get my home video! [up] [up]

I'll add some more.

Back to the Hurt Report. As far as I can tell, the Hurt Report makes one claim with regards to loud motorcycle exhausts: “Motorcycles with loud exhausts are over represented in the study”. That is to say, that many of the accidents studied, involved bikes with loud pipes. From this very limited and dated empirical data, the conclusion is often drawn that that loud exhaust have no positive effect in the avoidance of an accident. I have seen very well educated magazine writers, actually purport this hypothesis as fact. Anyone with a high school class in statistical analysis knows better than to draw such linear conclusions from statistical data.

It could simply mean that more bikes on the roadways at the time of the study had loud exhausts. Or perhaps people who tend to ride will loud exhausts drive more aggressively ….or passively. Both of which can cause an accident. There is simply no way in my opinion, to really know from this type of data. But yet the quiet pipe crowd continue to use this flawed example to boost their argument. These are the same people who want your headlight on and you to wear a florescent vest to increase your visibility or sensory display.

I'd like to see a study specifically aimed at loud pipes vs accidents.

So would I but who would take it on?
- There'd be no public support to spend tax dollars on a DOT study to prove what the general public has already made up its mind on
- AMA already has a firm anti-noise position so they're not going to study it
- The aftermarket industry, who has the most to gain from a study that could prove "loud pipes save lives", don't want to shatter the myth that drives so many of their revenues

I don't think we'll live to see such a study.

the quiet pipe crowd continue to use this flawed example to boost their argument

True, and the "loud pipes save lives" crowd continues to avoid their burden of proof.

My XB12 has the full force system with a completely unbaffled megaphone. No other xb pipe comes close to the ear peircing scream this thing lets out... and yes it puts a smile on my face everytime
