I've been putting it off but I am finally going to bite the bullet and replace the stock exhaust.
Goals:
1. Eliminate raspy exhaust noise and replace with muffled low tone. Ok if loud at open throttle but would like it to be somewhat tame and mellow. Something with a db killer might be good so I can choose to be loud or not.
2. I use the center stand a lot so I want to keep that functional.
3. Prefer not to rejet, this is more for asthetics than performance.
I have a spare stock uncut system to experiment with but would also be willing to replace the entire system.
- Anyone have the Jardine system? Are you happy with it?
- From what I've heard on youtube, V&H is too loud and raspy for me.
- There are a couple youtube videos of a GS500 w/ a Yosh RS-3 can that sounds like what I'm looking for but it's hard to judge without hearing it live. Here's one: http://www.youtube.com/watch?v=UNURd3gti1s
- I've also seen a video of a GS500F with a GSXR1000 can which sounds decent.
- I've heard other cans on youtube that I like but they are from Europe or Mexico I think because I can't find dealers in the US.
Some of these options require a custom mid-pipe...ahem...know where I could get one?
Any input would be appreciated.
check out lasertone exhaust. its pricey but has the plug thing to make it not so loud if you choose to go that route. actually..it automatically has it on. you have to remove it to make it louder. very easy. you have to drill out the ribbet.
I just actually checked out the spiegler site and it doesnt seem to be ther e anymore. If you really want it you probably just email them. Its where i bought min e last year.
And unfortunately for you any modification of the exhaust from my reading of post here.. requires a rejet for your motorcycle to run correctly. you wont regret it.. its very worth the trouble.
Laser Oval Deeptone (taken from Wiki)
One of the more expensive full systems, the Laser Oval Deeptone is an entirely stainless constructed exhaust and comes with a removable endcap in order to change volume level as desired. Cost is roughly $500 plus shipping through one of the importers in the US. This system will fit the F model and does not require removal in order to change the oil.

If you're going for a look then you can't go past the Yoshi TRS - triangular (choice of mirror stainless, carbon or titanium). It also comes with a restrictor baffle. It is quiet at low revs and roars with full throttle up a hill. :thumb:
It can be bought new for ~$300, is a slip on and comes with the link pipe. Fully compatible with a centre stand.
a slip-on wont require a rejet but its recommended. a full system like jardine or V&H will require a rejet. if i were you i wouldn't cut corners do it Right the first time and your bike will thank you.

I don't know how you figure that. The TRS is a slip on and without the baffle in it it's as unrestrictive as any other (essentially a straight tube with perforations). The only difference between a slip on and a full system is that the slip on is using your stock headers. Seeing as the headers that come with the full system are essentially the same diameter as the ones they replace, where does all this so-called extra restriction come from?
The great benefit I see of a full system is not having to paint your headers periodically...
I have the stainless Yosh TRS... I love it, nice low grumble at idle and screams pretty awesome in the power band.
That settles it! I've been seriously considering the TRS for awhile but I've never heard a good quality recording of one on a GS.
There may be a fit problem because the collector pipe on my 2000 has a smaller diameter than the later ones that the TRS is made for, but I'd think a muffler shop could rig a spacer or something.
Where is the best/most reasonable place to get one?
Just what are the symptoms/problems of not rejetting? I can't see myself tearing down the carbs and doing this. Will my Suzuki dealer do it? We have a place downtown KC called Cafe Racer. I'll check with them cause they're probably more into mods than the dealer.
Thanks for the input so far! When I get this done, I'm going to make a high quality recording to post on the wiki.
BUMP...refer to the previous post right above this one.
So what kind of problems can I expect to have if I don't rejet?

the stock headers have an H pipe and the INNER DIA. is small compared to a full system that has no H pipe and a bigger inner DIA. I never said he WONT need one but he wont have any major riding issues like you would with a full. the only time a rejet is a must is if you change the air going in. so a slip-on with or with out a baffle wont do much if you use the stock headers. So in conclusion the headers are the most restrictive part of the exhaust.
Before you drop 3 hundred on a new set of pipes, I want you to know that they're ALL louder than what you asked for at the opening of this thread. Also know that the advice you're getting here so far is incomplete. If you change your pipes with either a full system or a slip-on, there is no need to re-jet unless you also replace the stock air intake. If you leave the intake alone, you can leave your jets alone. The truth is the most restrictive part of an exhaust system is a stock airbox!
Free-flowing air filters, racing pipes, and bigger jets all work together. Leave either the airbox or pipes stock, and re-jetting is pointless. Re-jetting will also cost you 15-20% in gas mileage, depending on how big you go, and you'll pick-up 2 or 3 HP at the most.
That's why bikes are designed the way they are. They're designed to give you ALMOST as much power as they're capable of with the best fuel economy and lower emissions. When you put big pipes on, bigger jets, and a wide-open air filter, you pick up a little power but pay a big price in efficiency. It's also loud as hell, no exceptions.

There isn't much that you have raised that I can agree with you on. I have the TRS bolted to my motorcycle and here are my experiences from that very system...
I have the lunchbox airbox and the correct rejet for that set up and have
not lost 15-20% in efficiency. In fact I have found it very difficult to spot the mileage difference - clearly my riding style week to week and whether I get caught in traffic on the commute is making far more impact on fuel use. The power increase (which people have dynoed on here) might not be much to write home about, but the
power delivery is noticeably improved. As is the warm-up time.
Far from being "loud as hell" I actually find the TRS a very flexible system - without the restrictor in it is certainly pretty loud; but with it in I find that the harsh edge is taken off, it purrs at low revs and gives a good note as the bike pulls under load.
And lastly the original poster stated that his prime motivation for changing his exhuast was aesthetic - which is a perfectly legitimate reason for choosing a new exhaust.

Not necessarily. I've found I'm getting the same economy as when the bike was stock! I have twin K&N's, full system and rejetted. My reasoning is I haven't gone too big in the jets and therefore is probably running a similar A/F ratio as stock. This is just my opinion, but I think people overjet and make them run far too rich. It may also be due to the way I ride, but I'm very happy that it didn't effect my economy.
If you guys are getting almost the same mileage after changing your pipes, intake and jets, you're babying it. Open it up some and your mileage will drop like a stone. If you think you can make those 3 changes and get more power and the same or more gas mileage, you think you're smarter than the engineering team at Suzuki. I will bet you a paycheck that you're not!
He asked for a small change in his exhaust note, but doesn't want it much louder, if at all. That's why I told him in that case he doesn't want to re-jet or change his intake as there's no need to. I would also recommend an adjustable slip-on for him.
I thought I was pretty clear, guess not.
Having said that, I have a V&H full system and K&N drop-in filter. I don't think it's too loud. I think it sounds great, and the mid-range flat spot the older GS with 33mm carbs has is gone. I didn't recommend it because he wants something quieter, which is basically what he has now.
I'm with Bill. If you rejet - well, you won't see much of a difference in mileage if you're just putt-putting, but allowing more fuel to flow is going to flow more fuel if you use your wrist. And if you're going to an aftermakert exhaust to get something quieter than stock, it won't work. It'll give a different sound, for sure, and one you might prefer.
If 'aesthetics' is what you're going for and you're happy with the way the bike runs now, it's probably cheapest and easiest to pick up a Yosh sticker off of eBay. ;) "If it ain't broke, fix it until it is..."
+1 for "If it ain't broke, fix it until it is..."
My experience has been that a K&N, rejet, and nice Jardine system has added immeasurably to my motorcycling experience.
Oh yeah, one more thing. He said his stock exhaust sounds raspy. Unless it has rust holes in it, it should sound like a lawn tractor.
yeah even rippin out past 9k mine doesnt sound raspy
your forgetting this bike is lean from the factory so a rejet should be done after getting the bike but its not required. adding a slip-on wont let that much more air out but it will lean you out a little more. adding a full system has no restriction letting more air out which will lean you out even more now we should fix that. rich is good it will keep the engine a wee bit cooler and power will be crisp. A rejet is not a must but for the sake of balance why not make the A/F ratio correct. too rich is bad too lean is bad. So before you tel somone they dont need to rejet if they mess with the intake and exhaust do it yourself and pull your plugs tell me what you see I bet they will be white. :thumb:
Mach:
I didn't tell him to change the intake. All he wants to do is change his muffler to something fairly quiet that doesn't sound like a rusty lawnmower.
There seems to be many of you out there who take issue with what people post without paying enough attention to what is being posted.
I never said you told him to change the intake. I said a rejet is a must when changing the intake. I did say dont tell people not to rejet when changing the exhaust. running too lean is bad for a bike. if he changes to a full system he will be running too lean, a slip-on will make hime leaner than the bike already is its bad but not too bad. these bikes are air cooled and running your bike a bit rick will keep the bike a lil coller and cooler is better. im not some online duche telling someone what i read somewhere else or think, Im a certified auto mechanic and know a thing or two about engine and carbs. Do i need to scan pages out of my old school book and show you why rejeting is a must for his bike with a full or slip-on? im tired of people giving stupid advice
Sorry for dropping out for a while. This thread seems to have come alive in my absence. Thanks again to all for the input.
Just for some clarification. I am currently running the stock exhaust system but one of the PO's drilled and punched out the baffle around the tail pipe and then tried to fix it by welding a round washer-like piece of metal in the opening. The result is a louder than stock, raspy, crackly sound that I don't like. An old lawnmower is a good comparison. I have yet to hear another GS500 in person so I really don't have much to compare it to. I just want it to have a more refined, lower, growly sound at idle and just above. I'm OK with it getting louder under load/full throttle but I'd like to be able to baby it in the neighborhood without being annoyingly loud. I'm not expecting to find anything as quiet as the original stock system.
As far as asthetics, I consider sound to be part of that. I'm not really replacing the stock system because it looks bad; just the sound. I'm honestly not a big fan of either Yoshi's or Jardine's logos but a new can will also approve the looks of the bike as an added benefit.
It sounds like if I keep the stock headers and air filter as well as leave the restrictor in the can, I can probably get by without rejetting. How will I know if I need to rejet? What are the symptoms? Back firing? Dead spots?
BTW, all you guys who replaced your stock exhaust with a full aftermarket system...Do you still have the stock one? I know from experience it only costs about $20 to ship it ground within the US so maybe we could make a deal. I know it's sacrilege to some around here but it is a less expensive alternative.
you can tell if you need a rejet by flat spots, bogging(that would be too rich of a mixture) or do a plug chop. if your plug is too white than your too lean) if it looks good and clean than your good. If you dont like the look of jardine or yoshi than V&H is your best bet but thats a full unless you get just the can and weld that on. I have an old can laying around but it has a dent and needs a good cleaning. you can also look at stock cans off other bike and have a shop weld it on for you no rejet will be needed if its stock. but remember the GS is lean as is and bumping the jets up a bit will give you better performance and make you bike happier.
Ha, before I got to the last line in your post, I was going to say - buy a stocker for cheap.
Unfortunately, a lot of people cut their stockers, but I bet there are some full systems out there. Before you put it on, clean the headers and paint them black with high-temp paint.
There are three stock fullk systems I see on FleaBay that aren't being bid upon; wait for one of them to end bidless, then message the guy and offer less.
Have you tryed to fix your stocker you said someone drilled holes in the cap thne welded a washer why not remove the washer then weld all the holes shut then check in side and see if anything else is cut. It may be cehaper that way.
I don't know anyone with a welder and the last time I asked someone at a muffler shop, he didn't want to touch it. Probably worth another shot.
Here's a video of a drilled out stock can that sounds a lot like mine:

It's got that same "fart can" sound goin' on.

I haven't re jetted and i dont have a problem. I will see if i can get you a decent sound recording of my pipe tomorrow.
what exhaust/intake you running?

That's what I'm talking about :D Thanks in advance for the clip! I assume you're running the Yosh TRS slip-on?
Mach, I don't like you calling my advice stupid when it's you who are wrong. I don't care if you're a mechanic. I'm the one who got an A in Physics three times. I've met smart mechanics in my life, and some who aren't so smart. Which are you?
You can put any exhaust system on an engine and it won't run ONE BIT leaner until you open-up the intake because the flow rate is decided by the most restrictive component in the system, in this case, the intake.
And you keep saying the GS is too lean from the factory. To you, maybe, but not to the rest of the public. If it was actually too lean it would hesitate all the time and bake the plugs, and it doesn't. Who would buy a new bike that ran like that? The answer is no one.
its lean from the factory not too lean but it is lean. good for the stock setup. I already changed the exhaust to a slipon without a rejet the bikes plugs changed from being clean looking to a pale white. you may not know it but t hats not a good looking plug i was running to lean. i was still running the stock intake. So I went ahead and added the proper jets the bike ran fine the plugs looked good. I purchased a V&H full setup added that to the bike with stock intake no rejet. wow the bike ran like shaZam!. so i installed pod filters and rejeted and the bike ran ok. so adding a slipon is fine but chsnging the headers will give you more flow. have you seen the stock pipes next to an aftermarket pipe? i have and its a big change.
lets compare
o=stock pipe O=aftermarket pipe
Its not the same as a car the bike wont adjust itself neither is it EFI where it will also fix itself.
I see you have a full exhaust put the stock airfilter back in and put the carbs back to stock setup let me know how your plugs look.
