Loud

[lumpoffire]

I really like my Yosh pipe (got it from AlphaFire).  It looks good, it's lighter, it seems to improve performance.  But..

It's LOUD.  Maybe it's me, but I didn't expect this much noise.  I've had a Kerker 4-1 on a ZR1100, a Supertrapp on a FT500, a Spec II on a Seca 650, full Yosh on a Ninja 1000R, and a set of Yosh Zyclone slip-ons on a 750 Zephyr.  I don't recall any of them being this loud.  At least I'm getting good mileage (58mpg on last tank); but it's probably from short-shifting because of the noise.

Is there anything that can be done to the baffling to quiet an aftermarket pipe down a bit?  Could it be a source of some of the noise is the junction of the two parts under the bike?  There is no clamp/spring/etc., just a slip-fit.

TIA. D.

Glad you like it :lol: I know what you mean though. I had a full V&H on the old '92, and it was surprising at times. I got used to it after a few weeks running around town, but if I ever went on anything resembling a long ride I needed ear plugs. Hell, I began to ENJOY ringing it up with the V&H just so I could hear that sucker roar.

All the bikes you posted are 4-cylinder engines (except for the FT500, which was kinda wussy anyways), which are typically quieter in the lower ranges (until you really wind them up, when they scream at you). Twins on the other hand have more volume at lower RPMs. I forget why.

Alpha,  your explanation of why 4s are "quieter" makes sense to me.  My FT single had a Supertrapp tuneable baffle; probably didn't have more than 4 or 5 discs, otherwise I hear those singles could be made to thump really loud.  

I'm going to give it some time to get used to it.  I just don't want to piss off the neighbors too much at 7:30 Sunday mornings.

You don't have a potato-potato-potato cruiser with straight pipes. You'll be fine. :lol:

Ha.  I try to warn people that this is usually the case with aftermarket exhaust crapola, but people hear what they want to hear and if someone chimes in that it's not so bad then that's what they will decide to believe.  

If you can't live with it then I like the idea of adapting a higher quality stock silencer off a Gixxer or the like.  Ebay.

I like my bikes loud...my gs is loud, my cb has straight pipes, the zzr has yet to be modded and is therefore too quiet for me. But then again I ride with alot of Harleys...

Darn.  I guess I just wasn't paying attention to you.

I had heard that Yoshimura systems were a bit quieter than, say, Vance & Hines, and others.  The Yosh system on my old Ninja was fairly quiet, but perhaps it was the Zyclone system with a "street" baffle.  I'm not sure if the Yosh GS system uses a different design.  Probably something in what AlphaFire says about twins; maybe they're just inherently louder when "opened up."

The Yoshimura IS quieter than the V&H, if I recall correctly. They are just both significatnly louder than stock. Stock exhaust it like a whisper. Yosh is kinda like normal talking, and the V&H is drunken arguing.

Twins are loud, no doubt.  I do have a Yosh Zyclone on an inline 4 and there is some noise reduction technology built-in.  At least they make an attempt.  It still had the annoying popping when decelerating w/throttle closed.  I took mine apart and did some additional silencing--probably at the expense of any power gains it originally offered, or worse, but, hey, it's light and looks nice.

yeah i was thinking it was just me!  After about 30+ mins going 55+mph When I get off my bike my ears are ringing.  I have a V&H exhuast.

just be glad u don't have a d&d, now those babies are annoying as hell

There is a thingie called "dB killer". It is a little thingie you stuck at the back of your pipe. It reduces performance only bu couple % but reduces the noice significantly. Try to search for one.

I have a BSM full system, which is in the perfect middle between quite and loud. Especialy when engine-braking from 5k to 3k rpm.

3k to 5k? I am rarely at those RPMs Only in parking lots and when sitting at stop lights

I like my bikes loud, but not straight-pipe-Harley-crap loud.

Make sure you have no leaks.  Fire it up and move your hand all of the way from head to can, on all sides of the pipe, feeling for puffs of air.

I make that whole post for nothing.

Hi, I am a newie and have few questions to you all experts out there. I recently got '05 GS500F as first bike and loving it but wondering what exhaust will fit my bike to make it louder than the stock (I heard V&H for GS500E will work). Also, how or what do I need to do to put the new muffler on? welding? take it to a shop? Any suggestions?
One more thing, is there any frame sliders available for my bike or can I just bolt one on(any kind)?

Thanks experts.

[Roadstergal]

OK, maybe I didn't.  Good thing I cut instead of deleting.

Direct your eyes to the blue links at the top of the page - the Search will do you much good.  Simple answer to the last question - no, there are none.  For longer answers as to what options aren't quite frame sliders, Search All Terms for Frame Sliders.  Search for Wileyco and Flange for exhaust options.

[Roadstergal]

Dude, you posted the question once already.

[lumpoffire]

Roadstergal,

Thanks for the suggestion.  I don't seem to have any leaks.  One observation: the pipe seems to stay relatively cool.  After shutting off the engine (after a ride of 5 miles or so), I can put my hand on the cannister without burning.  With the mild rejetting, I wonder if the engine is running a bit cooler now.

Thanks to all for comments/suggestions.

[Roadstergal]

If you start the bike, drive 5 miles, and stop, the bike is not going to be warmed up (unless you take a lot of breaks along the way).
The can does cool down pretty darn quickly.  It's the engine block that gets hot.
