Loud Exhaust

Many of you will take this attenuator solution as justification to run loud pipes.

But, hold on. There are differences between this system and loud motorcycle exhausts.

Noise Direction

 

One big difference between the attenuator and loud bike exhaust noise is that the attenuator is directed toward the driver and is accompanied by bright flashing lights. The sound from a motorcycle exhaust is mostly directed rearward.

Sirens and horns are pointed forward for a reason. And when you consider that most multi-vehicle motorcycle crashes come from in front, not behind, you can see the argument against loud pipes being responsible for saving lives.

Also, sound bounces off buildings, etc and is absorbed by vegetation, etc. This means that locating the source of the sound is tough. And the time it takes for a driver to identify your location could be way too late.

Can You Hear Me Now?

Another argument against loud pipes is that even the loudest exhaust may not be heard and then responded to in time. This is because cars are sound-insulated to the degree that moderately loud music or an AC fan on high can mask, mute or muffle the sound until it is just part of the background noise.

An open window certainly helps in this regard, but almost every vehicle on the road today has efficient air conditioning, which means fewer and fewer people drive with windows open.

OK. Let’s assume that your loud pipes alert a driver that you and your bike is in the vicinity. But, to avoid a collision requires the driver to know exactly where you are. Knowing you’re in the vicinity isn’t enough.

An example is a driver traveling in the same direction (you’re not riding in a drivers blind spot, right?) not being able to see you and then cutting you off. Unfortunately, your loud exhaust noise won’t tell him or her whether they can change lanes or not. They may look first, but maybe not.

One scenario that was pointed out to me that may justify loud(er) pipes is when in very slow traffic (think L.A.) and you are lane splitting. At these slow speeds it’s possible that a driver could hear a bike approaching from behind and will think twice about changing lanes. But, thankfully most riders don’t have to endure (or at least avoid) that extreme traffic situation, which brings us back to questioning th validity of the loud pipes strategy.

Mixed Meaning

Let’s assume that loud exhaust systems can get attention. But what exactly is the noise conveying? It’s not telling drivers’ to pull over or run for cover, so what do we expect drivers to do exactly?

A Reliable Solution: Be More Visible

If your real goal for having loud pipes is to get drivers’ attention so they don’t cut you off or crash into you, then the arguments made in this article suggest you’d be wise to consider other (or additional) strategies. Here are some suggestions that are likely to be effective.

Bright Clothing

Now, I know that hi-viz jackets, vests and helmets may not be your thing. But, you don’t have to go all HAZMAT to become more visible. Harley-Davidson predictably sells mostly black jackets to satisfy their traditional customer base, however look beyond the badass blackness and you can find a few more visible options.

Those of you not as encumbered by traditional style requirements have many options available to you, including the aforementioned hi-viz, but also white or bright colored gear that looks both sporty and stylish…and helps you be seen better in traffic.

Lane Positioning

One of the MOST effective tools for being seen and avoiding crashes is effective lane positioning.

Select lane positions that put you in open view so drivers can see you. This means not tailgating the car, which may be using a new car shade, or truck in front and riding in the left or right portion of your lane to make sure drivers waiting to turn into or across your lane can clearly see you. It’s up to you to select lane positions that put you in plain view.

Even if you are in plain sight, don’t assume drivers see you. There’s this thing called “motion-induced blindness” where stationary objects disappear when surrounded by a moving background, such as busy traffic. Get drivers’ attention my moving within your lane. You can simply change lane positions, or do a slight weave as you approach.

Horn

You can rightly argue that a horn is in the same category as loud pipes. But, there is a difference. Unlike loud exhaust, a piercing horn has a more commanding meaning than the noise from loud pipes (yes, even from a “barking” throttle blip). Remember earlier when I talked about how the types of sounds communicate different meaning? Yeah, That.

The horn on most motorcycles is anemic at best and unless you fit an aftermarket blaster on your bike, you can only rely on this being effective at low speeds. Check out aftermarket horns at Twisted Throttle.

Your Choice

Before you get all cranky thinking I’m not on your side. I believe that any added tool for being seen is worthwhile.

However, (you knew this was coming, right?) loud pipes can’t be relied on for adding the kind of conspicuity necessary to avoid collisions…visibility. People have to see you!

I’m no scientist, and this is not based on empirical evidence, but experience and logic suggest that relying primarily on loud pipes for visibility is a weak strategy. Does it help? To a degree. But, in my opinion, the effectiveness is trumped by the risk of discrimination from authorities, the disdain from your neighbors and the perpetuation of the outlaw image puts us in risk of heavy handed regulation.

Of course I know that this won’t convince anyone already enamored with the badass sound of their bike to dig up the stock exhaust from the basement. However, I hope this article gives you pause before you repeat the old saw “Loud Pipes Save Lives” without at least considering that this strategy may have a relatively minor effect on preventing crashes.

Admit it…loud pipes make your bike sound better and is a way to experience the raw, visceral power of your awesome machine. But, ask yourself if perhaps they aren’t as effective as most people think at saving lives.
