I've been selling on fleaBay since 05 and had an eBay Store for about 6 months and there are options with an eBay store that save you money in the long run if you can move enough product. You can also link to your own website and so forth so no big deal redirecting sales.

As long as you're not listing over 5 a month, you don't get charged a listing fee =) Plus Ebay fees aren't that bad, this is straight from ebay:

The first 5 auction-style listings that you list on the site in a 30-day period are eligible for $0.00 insertion fees. The 30-day period starts with your first eligible listing. You'll have 4 more opportunities to list with $0.00 insertion fees during those 30 days. After the 30 days pass, the next 30-day period starts with your next listing that's eligible for $0.00 insertion fees.
Only auction-style listings are eligible.
Listing upgrade fees still apply, such as bold or listing in two categories.
Final value fees still apply. If your item sells, you’ll be charged 8.75% or $20 per listing, whichever is lower.

So seeing how for $634, $20 would be the lowest fee, add 3% Paypal fees to it, you end up with $39.02 for extra fees if you sell. Basically what I'm saying is if you're willing to part with $40 per sale, it wouldn't hurt just to list up to 5 a month on eBay to expand your consumer base.

Finally got to look at it a little closer, I'm thinking that one is a 2" core (cost on the can is about $250) and I'd be willing to bet $$ it definitely lost power over stock. Based on the pale gold discolorations, it's probably only been run a few hours at the most. It starts to change within 20-30 minutes.
I will say, that is a pretty looking exhaust system. Without numbers to back it up, I don't know that I'd buy it.


I played some today, couldn't take not hearing it for too long. Tried using it as a snow blower. : )

I emailed the seller of that custom exhaust on Ebay and all I could get out of him was that he "didn't want it any more". I asked why, as well as if he had a sound clip, dyno chart, etc, and he didn't reply.

If it went for CHEAP, I'd buy it and give it a try just for the hell of it, but last I checked it was at $250 or more and I don't want to spend that kind of money on some one-off with no supporting information on it.

I do like the looks of that 5" round muffler, though.

That exhaust is from Bryan Bermisderfer's bike. It was built by HDFR to use while they were waiting on the Buell race exhaust to become available. It is a Burns Stainless muffler. I was told it may have lost a bit of power, but back to back runs vs stock weren't done to be sure.

Well, give me another week. I've got parts on the way and they'll be here Friday, I'll try building it this weekend if I can. I've got a couple others to build first, then I can play again.

Why couldn't the guy holding the camera show the system instead of just pointing it straight down the whole time? That part of the video was annoying. The system sounded decent enough.

John, I'm sorry, I was just messing around and suffering from withdrawls since it's too crappy to ride. I'll see about setting up a tripod so I can record and not move. I've got a good video camera to use, I just never do. All of these videos have been done with my cell phone. It's a Nokia N75. I'm not a film director, I was just doing it for fun. Someone had asked for longer video and they said they just wanted to hear it and they were not worried about seeing it. There's plenty of good still shots of it to study in depth. If you'd like the originals, they're 2 mb in size each, I'll be happy to email them to you. I probably have over 100 pics of that size as I documented this system.

Sorry about flying off the handle a little D_adams, but I was anxious to see the design of the pipes from the headers to the silencer. I'll PM you my email address, thanks.

There were quite a few good pics on the first page of this. The better ones started here. http://www.badweatherbikers.com/cgibin/discus/show .cgi?tpc=290431&post=1705534#POST1705534

Probably one of the best early pics of the collector part is this one although it's only tacked together here. The full size pics are about 3300x2500 for resolution. They're huge.

Took it for a ride today to work, for those of you interested, it's definitely quieter than a Jardine and is deeper in tone. There's no real drone or buzz from it, especially at 60-80 mph. I ran it at various speeds to see what it sounded like and it almost sounds like a HD motor when it's down at 2500 rpm in 5th or 6th gear on the hwy. I guess it was about 45-50 mph in 6th, it runs around that range. Fairly quiet overall considering what it sounds like at idle without anything to kill it's sound, I had foam ear plugs, a balaclava and full face Arai helmet and it sounds very good.

On a side note, it was freakin cold. Current temp here is 24 degrees. Brrrrrr.

Yes, it has the 062 flash also. I have not done any tuning to it yet. I intend to do something eventually though.

D,

Where are you getting the actual through pipe, end caps and body for the muffler if you don't mind me asking? I have found all the other components for an exhaust except for those...I can't seem to find them anywhere.

Thanks in advance!! (you've inspired me!)

Looks good! Haven't been able to sample the sound clip yet. I've always liked the sound of the Magnaflows on the XB Buells. Been looking for something similar for the 1125.
On a different note, has anybody experimented with two headers all the way into the muffler (instead of a collector) and building internal baffles to create the required backpressure? There used to be a system like this for the tube-framed bikes.

You can get most of the stuff from http://www.stainlessworks.net/ but they only sell completed mufflers. They have sizes that will fit. Another option is http://www.pypesexhaust.com/

Gemini, I don't think I got one from you. Yep, I'm staying pretty busy.

Buellerthanyou, now you're going to make me stretch a little. It can be done, but I don't know what kind of results you'd get from it. As far as sound goes, I'd guess a Magnaflow is close for the rumble on the current setup. Wide open, mmmmm, it's going to get your attention. If I can find an easy way to do a crossover inside the muffler, I might try it, but I doubt it will happen. It would probably sound good, but not perform how I'd want it to.
I see a lot of pipes that claim good gains but it's usually up near the redline where they post their gains, I'm happy with not losing any at all, looking a little different and sounding a lot better. I grew up around muscle cars from the 60's and 70's, so I've always appreciated a decent sounding exhaust. I've heard quite a few pipes for the 1125 and there's only two that if I couldn't do this myself, I would have bought. Buell race pipe or a Drummer. Mine may not be as polished looking or get the same performance gains as either one of those, but it doesn't look all that bad either. I guess the flip side of it is, for mine, you don't pay for the name.
Yet. : )

"has anybody experimented with two headers all the way into the muffler "
The Remus systems look like that.

I've been meaning to ask - What are the pros and cons of merging the pipes later (longer primary headers) like Dean has done? Longer would equal more low end? Deeper sound? Shorter would be better for top end and cheaper?

Most of the slip ons (FMF, HMF etc) seem to merge straight away, as does the standard muffler. I've noticed the Termi slip system merges later though.

You might want to look at a cutaway of the stock pipe again. It looks like it merges right after the connection point, but it's not even a true merge collector. It's fairly large, maybe 3" ID? It's huge. From there, it goes straight into a 2.5" pipe.
Here's the stock cutaway.




As far as cheaper, yes, if you run a large business that stamps out systems for hundreds of different bikes and have a massive amount of resources available to manufacture them, you can get an inexpensive system and have it replicated over and over. For someone like myself, I'm my own R&D department, marketing department, welder, salesman and whatever else I need to do. I can't compete on their level and I don't want to. I want to hand craft them, one at a time. I would imagine they can crank them out in an hour with the equipment they have available. I cut everything by hand, then test fit, then weld it. Each one is just a little bit different. You might not want yours tilted the same as mine, so I make it the way you want it done, not how someone else thought it should be. The odds of someone else getting one exactly like the one you have is very slim.

good stuff Adam, nice honest work!!
that pic really shows the R&D they put in the std exhaust. was it packed?
by the way, dont make the same mistake i did.
i packed mine with s/s wool & f/glass but the glass strand were a bit too short so i get bits flyin out time after time
should try that 3.5" /3" one day. the different balances in sizes makes it sound like an odd fire, alittle ducati style.

Hands down coolest thread ever. I have an appreciation for fabricators, I couldn't fab something straight to save my life.

I apologize if you have already answered any of the following...

1: The perforated inner sections. What is that material called, did you perforate it yourself or is that a type of stock one can obtain easily.
2: The outer shell. How the h*ll did you get such a perfect shape.... flat roller etc??
3: I am a big fan of the stock exhaust from an asthetic perspective, I just wish the EPA hadn't had a hand in designing it (if you get my drift). Particularly I like the over under shotgun looking exit ports where they placed them and how they are oriented, what can I say I like it : ) Do you have any designs that could or would replicate this look in a non EPA "blessed" unit. Not looking to rip the windows from the panes, just ease breathing and add a couple DB's.

1. It's called a perforated core. The louvered type are called...louvered cores : )

2. He bought it from an exhaust company that sells the components. I won't mention the name in this thread because he's making money off of these exhausts.

Eece_ret -- It's a perf core, I buy it that way, pre-made. It's easy enough to find, just finding it in the right material is the fun part. I also buy pre-rolled shells, caps and all the other internal parts I need. I buy stuff from different vendors, depending on what I need. I do not keep a lot of material on hand, but I'm slowly building up a small stockpile of parts.

Modifying the stock pipe, yep, it's been done a couple of times, I do that mod also. It gives it a little more thump, but it's not really super loud. You can hear it running down the highway after the mod a lot clearer than stock. It sounds pretty good, Geforce got the first one.
Here's the final version of it.

It's a 3.5" x 8" x 12" case. Here's a pic of the "low slung" version. I'll post up one later tonight with it tucked a bit tighter.

If you were to angle that up to follow the bottom of the case how about an angle to the rear end cap? That would allow for even larger diameter turn outs.

Thinking like a wood butcher here...but I can imagine pushing the premade oval can through a bandsaw at the appropriate angle and getting a "slashcut" and then making a template and cutting out an endcap to weld it up. The greater height of the angle end cap might change the sound too, even with the same size turn outs you are using now.

Man I want to play with metal : D Looks like too much fun.
