Ok.. I guess nobody wants to say it, so i'll do the honors.

That looks like the typical "tuner" fart can usually available on eBay for well under $50. If you don't care about the brand, might as well pickup one of those and custom chop the actual canister to your preferred length, reattach the end cap, slap it on your bike and call it a day.

thats a good point you just made man... can you use a car muffler on a bike if you find one that would fit a good?

Why and why not plz!!!

I'm kinda curious whether they'd give a similar discount on the 14", road legal version of the pipe:

http://www.delkevic.us/?section=shop&product_category=exhaust_s7rhj&sub_category=stubby__13_320mm_stainless_steel_trioval_mufflers_2noxv&product=suzuki_stubby_carbon_fiber_mufflers__silencers_14andquot_350mm&variant=Suzuki_SV650_1998-2002-1690&start=0&search_term=&order_by=

Seems like that if one fits, the other probably should too.

I don't even know what "road legal" is. I mean you probably can't get away with straight pipes on a GSXR, but you could probably straight pipe your GS500 and it wouldn't be as whiny OR loud.

No. Different diameter pipes. Why not buy a real exhaust? I never found the appeal to fart cans. A good slip on cuts weight and improves breathing, but not as much as a full pipe. These fart cans only make your bike sound like it's better than it actually is.

Interesting viewpoint ..... however,

The diameter issue is a very very minor hiccup and easy to overcome with an adapter since since we talking just a small difference between the stock exhaust pipe OD (2" on the newer GS500F IIRC) and the 2.25" OD

What is the difference between a custom option like this and a "real" exhaust? What makes  a "slip on" good or better than this option than the fact that the installation requires no mechanical prowess?

correct me if im wrong here.. but all a slip on exhaust does is let off the back pressure which by manufacturer rules has to be there or else they wont be able to sell their bike due to emission laws. So when you modify you exhaust you in term void these laws and by doing so add a better sound and performance to your car/bike.... now some slip ons come with built in cats which are specifically made to your bike and some dont and thats why you have to rejet your bike so it will run right... if not it will run lean or rich depending on what you are running.

So in terms you can run almost any exhaust it all depends on what you like (louder, or a specific sound etc..) but almost all upgrades from you stock exhaust will in crease horse power from stock because they let out more exhaust then the tiny stock pip does. But if the pipe is to big or to free flowing you will run into problems such as to much or not enough back pressure, which i belive will make your bike back fire and run shitty as hell unless you increase the fuel/air ratio...

ONCE AGAIN PLEASE CORRECT ME IF IM WRONG... THIS IS JUST HOW I UNDERSTOOD IT!
(plz go easy on me if i am wrong lol)

The bike has a decibel rating. A sticker comes attached to the bike which lists this rating with the stock exhaust as Proof the sound coming out is "road legal". If you want to know what this rating is, contact your department of transport cause it is different for different jurisdictions.

As for a GS500 with no muffler not being loud, don't suggest such things unless you've tried them and know for sure. The GS500 without a muffler is way loud. Take off your exhaust system all together - just take it off at the headers - and see how you go. I can assure you, you will not have a "road legal" bike any more. Here, have a listen http://www.youtube.com/watch?v=FX72lcbozBs and pay attention to what his mate says "that is so god damn loud" (he ain't sitting on the sofa with his fingers in his ears for nothing). And this http://www.youtube.com/watch?v=TnEi336zAhQ even in his description "the sound was extremely loud!".

^^^ agree with mister, my bike came with no muffler on it! i woke up my whole damn neighborhood every time i started it!
it kinda sounded like a damn tractor rand like shaZam!, and i absolutely hated the damn thing man!

By the way my bike wouldnt even stay running unless my choke was almost all the way down!

"Back pressure" is a BS idea and is NOT needed for ANY 4 stroke motor. The only reason I can imagine for the rise of this idiotic idea is that some moron mistakenly linked "lack of back pressure" to burning of exhaust valves or poor running which are common in cases where the exhaust is upgraded but the AFR is not adjusted to account for the additional flow. When there is more air being pumped through the engine, it will need additional fuel to stay close to stoich. In cases where you don't compensate with additional fuel to go with the additional air, you will have moderate to heavy lean burn conditions which causers poor performance, over heating, burned valves and dead motors. In reality and for ALL technical purposes, back pressure by itself has ZERO significance for performance. Back pressure or in other words, restriction in the exhaust is something you want to avoid or at least reduce to the maximum extend possible.

Summary: The "Back pressure" myth = misinterpretation of poor air fuel mix resulting from lack of additional fuel to go with the additional air flow through the motor.

If you read the explanation i posted above, you can see why the choke (=additional fuel) fixed the poor running issue.. which, in this case, actually brought the AFR to the point where the engine could at least run.

Material and engineering.


Slip-On from a good company like Yoshimura

• Reduces a significant amount of weight by removing the stock muffler
• Improves engine breathing slightly. Not enough to really effect performance.
• Gains mostly come from the weight reduction in combination with better jetting and more breathable filters (pods, etc)
• Sound really good.

Full-system (Jardine racing exhaust, etc)

• Shaves off even more weight than a Slip-On
• Shaped pipes to tune engine breathing better than a Slip-On
• Paired with other tuning options like pod filters and such, can make a small improvement in power at the top end of your RPM range
• Sound better than a Slip-On

Fart Can

• Not made by a reputable company - hit-or-miss quality. Weight reduction not always worth the price
• Materials aren't always the best quality (ties into weight loss and engineering)
• Bought 100% for the sound.

Delkevic is a decent company. I'd buy a Yoshi slip-on if you're looking for a better quality product, but I've seen a couple SV650s with Delkevic slip-ons and people seem to like them. I don't have any evidence proving they fall into the fart can category, but I'm pretty sure they don't have Yoshimura's track record when it comes to exhaust design (both slip-on and full).

That being said, a slip-on is nice for the city where most of your (minuscule) gains will be spread out over your entire RPM range (weight reduction, etc). A full system is completely unnecessary for the road. You'll never see any of the power unless you're street racing or something.

as i changed the exhuast from a f%&ked stock to a good stock one on the weekend i thought id take my bike for a ride around the block and see how it sounded without the muffler...it idled awesomely and i loved it, took it for a spin however and it sounded ok accelerating, yet as soon as you back off the horible drone noise was discusting and unbearable and very very loud.

back pressure was a myth that started around people saying back pressure gave you more torque based on smaller exhausts on cars having more tourque and power at lower rpms and lacking power up to, not realising the issue was due to pipe diameter and flow, with the smaller piping actualy flowing best at a lower rpm (and no or little backpressure at lower rpm) and then not being large enough to flow up top, however they then put stupidly to big pipes that had no back pressure on them even up top, and lost power everywhere as the pipes couldnt support the velocity needed at such small volumes, they then came up with the idea that smaller pipes and mufflers that had back pressure would be needed, instead of having any idea about flow dynamics
