loudest 02 xr650L exhaust

i have a 02 xr650L engine in a 400ex frame and im looking for a aftermarket exhaust i want the loudest best sounding pipe out there and also if anyone has a clutch for this engine let me know how much i fried the clutch on it

white bros e2 series with the chrome tip installed is LOUD and sounds good!

Well best sounding to most of us on here is certainly not the loudest.

Loud is uncool. Just about everyone shows concern for NOT having a loud pipe, then you come along and want the LOUDEST made :thumbsup:

You have a right to purchase what ever you want but your main concern is loud and didn't even bother to ask how it performs!

loud is cool for me and ok yes what is the loudest best performing pipe out there

we all have our hiccups every now and again! i agree loud is not the best solution, but it is ok on a race track(closed course). sometimes i will open it up for a quick blast down the hiway to feel the raw top end these beasts are capable of. never off road due to the fact that the spark arrestor is part of the quiet core and we dont want to fuel any greenies with any more ammo!

I run a Pro Circuit T4 which increased the performance dramatically, is pretty loud at WOT, and comes with a spark arrestor.

XRs only full system with spark arrester is pretty loud. About 100 db.

Loudest? Open header, or straight pipe.

Quiet pipes save rights. :thumbsup:

i think i might try running the white bros E2 ive herd nothing but good about them and i have this engine in a 400ex and its pretty loud but it doesnt sound good with the stock pipe with no baffles

I'll 2nd jonr3 on that. Mine has the same setup as his and its almost too loud. The spark arrestor is a must.

Don't ride duelsports with open headers! We already have enough problems with tree huggers and we don't need anyone starting a fire and adding 1 more black mark against our cause.:thumbsup:

If anyone needs a bike with open headers , buy a Harley and go ride with the Asschaps .:thumbsup:

R......

Thanks for doing your part in ruining our sport.

Ahh come on and give the guy a break. Dude might live on 500 acres of his own property and wont bug one person. Quit crucifying everybody that wants a loud pipe. How many of you like rock -n- roll music....loud? Well start listening to sounds of nature in your 4x4 trucks with dual exhausts and 15' woofers.

Oh and I second the the WB E-series pipe!:thumbsup: Sounds great! Adds some extra umph the bike too!:thumbsup:

i live in the upper penninsula of michigan and we have thousands of miles to ride up here and not hurt anyone with our loud pipes 3/4 of the up has a truck with duals and lifted and tons of loud quads and bikes and sleds well lets just say at least everyother sled you see has pipes on it and is really loud

Then that settles it straight pipe with it sqeezed at the tip for a little back preasure.

Actually… Its attitudes like YOURS that is ruining our sport

Keep in mind your age.

You have the power to choose better paths for yourself than those of us who've learned the hard way. I know you are simply asking about pipes, but at least know what your choice entails.

Here's some stuff people ought to know that I found on a quick Google search:

http://www.hearinglossweb.com/Medical/Causes/co.htm

Loud noise is the most common cause of permanent hearing loss. Noise-induced hearing loss does not heal and cannot be corrected by hearing aids. No one is ever too young or old to suffer from the effects of hearing loss from noise. Protect your hearing by wearing the right personal protective equipment. Ear-muffs, earplugs and canal caps can all reduce the amount of noise exposure.

Do not use a "straight pipe" exhaust for tractors or any other engines. It does not increase power very much and often emits sound levels that can damage hearing.

Acquired Hearing losses

Hearing loss acquired from exposure to intense sound levels and hearing loss due to age are two different things. Acquired losses can be from a variety of causes. For instance, even a relatively unobtrusive sound like driving with a window open slightly for long periods of time can bring about a cumulative and permanent hearing loss in a narrow frequency band. Of course the amount of loss depends on the intensity and length of exposure.

On the other hand, exposure to intense broadband noise, such as motorcycles or airplane engines, can cause drastic loss over a much wider range. For instance, my father flew a Spad airplane in World War I. There was no hearing protection in those days and the open cockpit was only a few feet from the exhaust ports. He developed a hearing loss that cut off sharply above 800 Hz. Although he tried hearing aids several times as they became available, the loss was so severe that no improvement was noticed. Many years later, when a loss developed below 800 Hz, a hearing aid helped to restore at least that much. The dispenser at the hearing aid center told him that that he had tested many fliers from WWI and WW2 and could even identify which plane they flew just from the audiometer tests. Some viruses can even cause total hearing loss in one or both ears and hearing may never be restorable. Acquired hearing losses this serious can make it difficult if not impossible to adequately judge the listening performance of loudspeakers or other audio equipment.

Sound Ratings and the Danger Zone

Here is a list of sounds. They range from very soft to extremely loud. The number in front of each example is the typical decibel.

Decibel Example of Sound

0 Lowest sound audible to the human ear.

30 Crickets, distant frogs, whisper.

40 Kitten meowing, song birds, distant dog bark.

50 Refrigerator running, babbling trout stream, empty barn.

60 Average conversation level.

70 Chicken coop, busy restaurant. At this decibel level, noise may begin to affect your hearing if you’re exposed to it over the long term.

The Danger Zone

80 Tractor idling, barn cleaner, conveyers, elevators. These noises can damage hearing if exposure to them is for more than eight hours continuously.

90 Tractor at 50% load, blower, compressor, combine. As loudness increases, the "safe" exposure time decreases; damage can occur in less than eight hours.

100 Tractor at 80% load, pig squeal, power tools. Even two hours of exposure can be dangerous. With each 5 decibel increase, the "safe time" is cut in half.

120 Tractor at full load, bad muffler, old chain saw. The danger is immediate.

140 Gunshot, back-fire, dynamite blast. Any length of exposure time is dangerous. At this level, the noise may actually cause pain in the ear.

Keep in mind your age.

Earplugs! I wonder how much wearing just a helmet helps dropping the DB level. I know just the wind effects my ears while riding.

Apparently, wind noise is a big cause of hearing loss:

If I was 16, I could prevent this. But I have ridden many road miles, so the damage is most likely done. I did buy a Bell road helmet when they had the exchange program going (I sent in my old Bell LTD Full Face for credit on a new FF), and it has some air vents on the back/sides that are very irritatingly LOUD! Apparently, the never wind tunnel tested it. I covered them up with duct tape, and the noise reduction inside the helmet at highway speed was drastic. But even so, it (and most other helmets) are very loud. Foam earplugs make a huge (and inexpensive) difference. Easy to carry, too.

A brand new member here, so excuse me if I ask an already explained issue. I have a 2000 xr650L that is completely stock. I am getting a bit of backfiring when I decelerate. I plan to clean the carbs (to ensure proper gas flow) but if that doesn't work, I have to try a few new things. I have heard that the smog block-off kit cures that backfiring, but I want to know all that you guys will tell me about them. Also, how do you guys feel about K&N filters?

i swear by K&N filters i run them on everything i ever own best filters out there if you ask me
