Help with Exhaust - Which can or system will accomplish my goals?

[BassHz]

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. 

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.

[BassHz]

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.

[bill14224]

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.

[Roadstergal]

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..."

[joshr08]

+1 for "If it ain't broke, fix it until it is..."

[commuterdude]

My experience has been that a K&N, rejet, and nice Jardine system has added immeasurably to my motorcycling experience.

[bill14224]

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.

[joshr08]

yeah even rippin out past 9k mine doesnt sound raspy

[mach1]

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.

[bill14224]

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.
