Anyone using an aftermarket exhaust ??

Just did a quick search on the net looking for a nice end can for the Swing and thought id ask if anyone is using a aftermarket can is there any differance and can anyone post pics up on what there using
thanks
Rob

There's an ex forum member called bigbird who fitted a Leo Vince exhaust and wrote quite comprehensively about it. When he left all his posts were deleted, but I'm sure there's still other posts about the Leo Vince under Accessories and Modifications.

Thanks Meldrew Ive done a search on here and found loads of info and a video on the Leo ill continue with the search now mate
thanks again

I have the Leo Vince fitted, it sounds better and weighs a lot less but not sure if there is any boost to performance, maybe a bit more oomph in the mid-range. My dealer can get it, most of the scooter parts people are only interested in the smaller stuff. I got mine from easyparts.nl

Check out my album. You will see dyno tests with leo Vince, Power Commander, and variator. Improvements from all 3.

Hello Dan.
Am I reading the exhaust graph correctly when seeing that there's ~10 HP available at 13 MPH with the LV and the same ~10 HP is only available at ~40 MPH with the stock exhaust? This would indicate that the available power is greatly offset to lower RPM, right?

Not quite that big a difference alone. Read it again. That difference comes with the remap of the fuel/air mixture via the Power Commander. I am also wondering since its been so long since I did that, if that test was pre or post J. Costa variator.

The Holy Trinity for the wing is:
J.Costa Variator
Leo Vince 4 Road
Power Commander with custom map.

Some people prefer Dr. Pulley Sliders instead of the Variator because they seem to get some of the benefits of the variator but also some mileage improvement.

If you need more power on your wing beyond that then you are getting into turbocharging or nitrous. Or of course you can go to a different bike.

I have an Arrow fitted to mine.

Cheers,

Hi, newbie checking in here.
I have a twin exhaust fitted on mine (see avatar).
it's too loud and my neighbor knifed my rear tire twice.

Better the tire than you.

Install a stealthy security camera, catch him in the act, and press charges. Maybe you'll get the cost of 2 tires and installation back.

In fact, I just got it knifed this week so i was on ebay/amazon looking for a security camera.

Here's a link to a discussion and cut away illustration regarding dissecting a Ruckus muffler. The SW muffler should be pretty much the same as the Big Ruckus except the SW has another baffle at the rear and a second outlet. HTH

I think the stock header is too restricted on SW's.FMF makes an aftermarket exhaust for dirt bikes.The header has an expantion chamber giving 30% hp increase .
How its made ( the TV show ) showed one made in 2013 episode .

Well my 'Home Brew' custom exhaust is done -- or really it is functionally done. Though it looks great as is, there is a small ding I want to pull, give it a fresh coat of hi temp paint and there is a stainless steel guard that will mount to the front. Total cost was under $70US (and could have been under $40US), but it did take quite a bit of work.

The exhaust is only slightly louder than stock, gives a nice boost to aceleration, does not pop or backfire, (and the primary two things I wanted to accomplish) is less then half the weight and eliminates the cat converter (and cat related heat). So, does this tweak anyone's interest?   

I leave tomorrow morn for the Rockin' the Rockies Tour and will be giving the scoot a good scrub this afternoon prior to packing. I'll take a couple of pics then and get them posted with a basic explanation of the construction.

Interested to see your mod on the stock exhaust..... Dave

Looking at your graphs it appears there is a significant gain from the Leo Vince even without remapping but a good bit more with remapping? Does the gizmo to remap require any user intervention? Is there a particular supplier for the L.V. and/or remap gizmo that stands out? Do you have a convenient link to the remap gizmo? Thanks for your input.

LDB, the gizmo is called a Power Commander as Dan said in his post. And with a Google search for Power Commander it is the first thing that comes up. I did the search for you so if you click on the following link you can find the company.  Power Commander
I hope the link will give you everything you need to know about it. Google is a great friend if you use it.  

LDB,

The Dynojet website shows at least 4 Dynojet power commander tuning centers in Houston Texas proper, and many more nearby.

My source for Leo Vince is out of business. You'll have to find one on the web.

While there are maps available on the web, to really get the most from your bike, you need to have your bike custom mapped at the tuning center. If you want to buy the accessories, you can even have multiple maps created and switch maps on the fly. For instance, one map for power/sport riding and another map for fuel economy.

And don't forget the J. Costa! to complete the holy trinity of Silverwing performance.

Hi Dave, thanks for the reminder. I had forgotten I had not posted further info. I do not have a pic yet, but will take one over the next couple days and edit this post to add it. To outline the custom exhaust:

I studied many motorcycle stock exhausts for something I could mod for use on the Silver Wing. On my prior SWing I installed a GPR exhaust can made for the scooter. I did not like the radically upswept profile and so cut and welded the inlet at a more normal angle, then made a new mount strap. That could be seen in the forum's prior main photo. The GPR was super light, looked good but was louder then desired and had too little back pressure.

I had also owned Leo Vince exhaust on 2 other scooters and very much like them. But being an incorrigible tight-a**, and habitual DIY-hacker-repurposer, I wanted to use something I could get cheap. It also had to look good, perform well, be lighter, eliminate the cat convertor have back pressure and tone similar to Leo Vince (due to additional baffling compared to the more straight through exhausts like the GPR).

For this project I settled upon using the right side exhaust can from a 2008 Suzuki Hayabusa. The reasons it worked well...
1. The Hayabusa is 4-cylinder, 1300cc, ~150hp and the exhaust exits into 2 cans.
2. Though fairly quiet, each can is designed to handle half of the engine -- 650cc at 75hp. So each can handles the exhaust pressure pulses of 2 high rev cylinders, similar to a SWing engine.
3. The 'Busa exhaust exits four cylinders, then two cylinders funnel together on each side into a cat convertor, then exit into an exhaust can, one on each side. Basically a 4 into 2 system.  Since the exhaust cans are behind the cat, it is a seperate unit and did not have to be used. The SWing cat is integral to the exhaust can and cannot be seperated (without radical surgery).
4. Stock SWing exhaust is about ~20lbs weight, modified 'Busa can and connector pipe is -10lbs.
5. Steel casing and integral cat on the SWing retains considerable heat (good for muffler cooking). 'Busa exhaust can is dual layer aluminum and dissipates heat well. Exterior remains cool enough to not need a guard.
6. The back pressure is enough that there is no backfiring and bery little deceleration pop. If I disabled the PAIR system (no longer needed as there is not cat) there would be no pop.
7. Looks damn cool!

The results are excellent! It has a nice little growl at idle and initial crack of the throttle, but is no louder than stock in riding. Just like the past use of the GPR exhaust, I can feel the difference from removing +10lbs of dead weight from the far rear of the scooter. Performance is more improved than I initially thought. The engine revs quicker and more freely. Acceleration is considerably improved and torque is great. It was an absolute pleasure to ride on the Rockin' the Rockies tour. In a roll-on from about 20mph, it out accelerates my buddies Suzuki V-Strom 650 (both he, and the bike, are lighter).

The 26gm Dr. Pulley sliders lowered 60mph cruising rpm by about 300-400rpm. This I had done a few months back. The 'Busa exhaust lowered another 400-500rpm. Since I live in the mountains, climbing is important --  the acceleration and torque improvement makes the elevations much more fun. It feels like I may be getting MPG, but I ride 'briskly' and have not checked.

The process took quite a bit of cutting/welding/fabrication to the 'Busa inlet pipe. As the inlet pipe bolts to the can via a 3 bolt flange, the can needed no mod other than a 1/4 hole drilled in the hanger mount. Unless you have some fabrication experience and have cheap access to MIG or TIG welding, this is probably not practical.

I am very pleased with the results, appearance and (particularly) the cost.

When I post pics, the process will make more sense. For now, here is a pic of a 'Busa that the can could have come from.

My only interests are less weight, equal or less stress on the drivetrain, equal or better mpg. I have plenty of acceleration in stock form. Based on those interests, do I need the J Costa or is the Leo Vince and Power Commander alone adequate? What about the DR pulleys/sliders I hear about? Thank you to all who are responding.

I started a new topic on my custom exhaust BJ's custom exhaust

LDB:
I am running the Leo Vince 4Road, 24g Dr Pulley Sliders, a K&N Air Filter in a drilled air box, with a power commander. I made these mods to recover the power loss I experience from living a mile high and to optimize fuel economy. I had my bike on a dyno and it is delivering just over 41 hp to the rear wheel at 6,400rpms. I average 50 to 52 mpg riding like a hooligan. I had a J Costa on my first Swing. This one "feels" nearly as quick and delivers much better fuel economy.

I may go to the L.V. eventually for the weight savings and nice sound. Any mpg benefit will be a bonus.

I'm not a mechanic and do enjoy reliability. Stock Hondas are reliable. In my VTX days other big twin riders would add on exhaust, Power Commander, a trick air scoop and some other stuff. The bikes never ran right. What good is 5 more HP on a dyno if the engine wont idle. For my nickel leave it pretty much stock.

AND after all those mods - it still idles perfectly....

Wouldnt be bothered to invest the heaps of money required to change the muffler. The minimal results dont outway the cost. I like my swing stock quiet. Like to have it quieter if i could. It is a scooter. However i would love to have a yoshimura muffler on my Suzuki GSF just to tick people off! It is a motorcycle!

I agree with Hot wings, when I had my bike shop ,I would install whatever customers wanted; Loud. obnoxious.what ever they wanted. BUT they ALL came back and asked if still had there stock mufflers ?

if you feel the urge to spend money.. please PM me for my address. I could use it on my annual trip to Nebraska.. lol this will be first yr not on a Gold Wing .wife and kids and friend says dont take the silverwing,its a 3000 mile trip 5000 kms, I am just gettng over broken tibia and ankle and cracked hip. might just haul it in my pickup and ride it down there.

Don't tell John Grinsel. He'll label you as just another pseudo rider.  :lol!:
