So I bought an M4 GP after people saying it was loud but I underestimated how loud. I love the sound of it but hate the idea of wearing earplugs all the time.

Has anyone after getting the M4 GP sold it for something quieter that didn't require ear plugs to ride and what did you go to? Does the M4 Street Slayer still require ear plugs?

Why are you opposed to ear plugs?

I have the Street Slayer and it's loud. Not as loud as the GP, but still loud. Any of the low exit ones will be an issue as the end of the exhaust is right below your ear. Street Slayer, Graves, Austin, etc will all be about the same. If you're going to change it out to avoid ear plugs then you're going to go with a rear exit exhaust like the M4 standard mount, Akrapovic, Yoshimura, etc. where the end is well aft of your head. Or get ear plugs.

Did I mention ear plugs as an option? :idea:

The more I am reading it sounds like a may not have a choice. I like the short exhausts so if they would all require ear-plugs then I guess I will be stuck.

I was mostly worried about possibly hearing someone talk to me like at a stop light or something. Someone in a car, another person I am riding with.

Read that the Graves is no where near as bad, maybe I will put the GP up for sale.
The Graves is the same thing as the Street Slayer. I have the M4, my buddy has the Graves. Sound is almost identical. Both are loud and right under your ear. Both will be better than that GP thingy, but they will still be ear-splitting at full song. I ride with headphones in and have no problem hearing the exhaust over my iPod cranked to volume 11. :deathmetal::rockwoot:

Don't fool yourself again. If you want a good sounding, quieter exhaust, none of these short GP-style pipes will work.

My problem with the M4 GP was how it just droned; it was loud and obnoxious at WOT or just cruising around; didn't matter. The worst was long straight rides to the areas we rode in where there was no throttle modulation and the exhaust would just drone and hum the shit out of my ears. I eventually got rid of it for the Graves full system.

Definitely not as loud as the M4 GP, a lot more subdued. Also, the exhaust tone and pitch changes when you are in the throttle and not into as much. So if you're just putzing around town it's not going to drive you insane with its obscenity but if you get into the throttle, she opens up and let's people know you're around, just not nearly as bad as the M4 GP.
This is exactly what I was looking for and I should have explained better. Droning is the biggest issue, the noise level was not as obnoxious as it just droning. Glad to hear you did the exact thing I may do and it worked out for you. Do you tend to wear ear plugs or no?

Not really. Probably should though; I'm already 50% deaf thanks to the military.
:iamwithstupid:

Short, long, or stock... earplugs are a good idea. If you make riding a lifestyle choice it will damage your hearing without earplugs. Trust me. If you want a fun confirmation of the fact, just hang out at local meet spot and wait for a group ride to come roaring in from a pass.... non-earplug groups are usually damn-near yelling at each other for a good 30 minutes after a good ride & they don't even realize it. :)

exhaust or not, 20 minutes at hwy speeds, just wind noise in the helmet, will cause PERMENENT hearing loss.

personally,I cant stand to ride without plugs anymore. you can still hear and see everything going on around you.

once hearing is lost... it does not heal itself, and return. IT'S GONE! YOU ONLY HAVE ONE SHOT, DONT LOSE IT. Ski

Priority One: ear plugs. I always wear the monkey suit and boots and good gloves but idk what you do for protection but without ear plugs you'll suffer from mega exhaustion in very little time: like about 15 minutes.

Clearly there are some misconceptions here about about wearing earplugs while riding. Take the time to read this article.

I've worn earplugs since I first started riding years ago. Didn't matter if I was on my 300 with a stock can (quietest bike I've ever ridden) or my 600 with straight pipes... the exhaust dB levels will always be trumped by wind noise above certain speeds.

Wind noise on a bike at 60 mph with a full-face helmet on is around 100-110 dB. Those levels can begin to cause permanent hearing loss after 30+ minutes of exposure. Think about that next time you plan on riding.

I don't have any problem talking to others, or maintaining awareness on the road, or doing anything else other riders do. It boggles my mind that few others I know wear earplugs while riding, even after I've explained all this to them... then again, unlike them I already have about 50% hearing loss and need to save whatever I've got left.

I plan to read the article above and will highly consider wearing ear plugs at least more often/on long rides. I was not aware that it was such a risk until now. My dad has ridden since 18y/o and I don't believe he ever wore them so I didn't realize I should. (I also don't think he has any hearing loss but...)


About the exhaust:
I have ridden more since posting the original post and have been wearing ear plugs as I still have the M4 GP. It's STILL too loud even with earplugs and the droning goes right through the ear plugs. I have taken the advice and I ordered a Graves slip-on. Once I get it and put it on I will post if it's any better. I will also have a slightly used M4 GP up for sale at that point.

Definitely rock ear plugs. Its fun if I know Im not getting on the freeway to hear the bike and stuff without them in, but I tend to feel more focused with ear plugs. It feels like the rest of the world is less distracting and I focus on riding more. That and I very much appreciate having my hearing. Its also why I wear ear plugs and work and such. Loud noises, especially constantly loud noises, will give you permanent hearing issues. Ive noticed a alight reduction in exhaust noise from wearing ear plugs, but that doesnt feel nearly as drastic as the reduction in ambient noise.

Skydork has said this, those stubby little exhaust will all be loud. They might have a little different character because of the manufacturer, but theyll all be loud. Just isnt enough baffling and muffler to reduce that much sound. Tone can be slightly altered though.

One of the troublesome things about hearing loss is that it's rarely immediate, and is therefore difficult for the person to realize the damage being done over the years - if they do notice a difference, it's a small and seemingly inconsistent one, and they get used to it. A lot of people also assume that their hearing loss is simply due to them "getting older", but this is inaccurate. That belief is especially the case with older generations, who grew up and had careers before we recognized the importance of hearing protection.

Even with a properly fitted helmet (which is another thing a LOT of riders get wrong!) and my best set of earplugs in, my 600's straight pipes had a similar "drone" to them when cruising at highway speeds. As others have stated, this is simply the nature of any shortened exhaust system. Unfortunately, there isn't really an easy work-around for it. It's a trade-off between short and full-length exhaust systems.

I've also noticed that wearing earplugs makes a tremendous difference in my concentration and focus while riding. They cut out a lot of ambient noise and allow me to hear my bike a little clearer, which can help me notice any problems and also allows me to shift up and down a lot smoother than when I can't hear it and can only feel it.

Cutting out as much of this noise as possible also helps significantly with exhaustion. Since my weekend rides tend to be anywhere from twelve to twenty hours round-trip, this can make a very big difference for me and the people I ride with.

I bought my zx-10r with a M4 GP Exhaust already installed in it; even wearing ear plugs, the noise was unbearable; the silencer that goes inside the pipe didn't make a difference. I hated that pipe with a passion. I went ahead and sold it and purchased a Yoshimura R77. The Yoshi was too quiet, so I cut it down by 3 inches and now sounds awsome.
