Hi, I'm just updating my info, maybe it will help find this elusive exhaust. My scooter: 2005 Jieda / Hunter50QT-4, 2T minarelli 1PE40QMB, HORIZONTAL [not vertical as I was told] I'm still on the hunt for a performance exhaust to give me a little more "gusto" and "noise". There are @ 5 dealers searching for a compatible exhaust as we speak. I would truly like to thank everybody that has helped so far, and a nah to you dipshits that think it's a big joke. Some pics might help, big problem is at exhaust port and flange fitting.

Buddy, I am pretty much a noob about scooters too, but even I can tell you that is NOT a 1PE40QMB engine. Sorry you are not getting the information you need, I truly wish I could help you. I can PROMISE you no one will care to help you when you take the tone you have. Don't get too defensive if someone calls your engine krap. The truth is most ALL of the Chinese clone stuff is krap, but for some reason we are rather fond of it. Mostly a love/hate relationship with all of the Chinese krap I have!

You need some measure of "performance" to begin with before folks stop kinda scratching their heads and wonder WTF. You gots no transmission.... what you have there is the single speed chain driven lump that, at the best of times, wouldn't pull a sick whore off of a pisspot. If you are absolutely desperate to pretend you have something there Technigas has an exhaust for a pocket bike you could bodge on there: www.tecnigas.com/o/model.php?codi=38&cat=9&idioma=en

oldgeek...hey, sorry i didn't mean to offend u or anybody else, as i must have. it's just, when u have more knowledge out there than i have, you really don't need replies that i have rec'd in other posts. my apology to all. ok back to my krap, lol.. i was told it was a pretty peppy engine. 1PE40QMB is definitely engraved on the crankcase casing, no doubt about that. u are right about luv'n this chinese stuff. wish i can find a compatible exhaust? sorry again, thanks again......bob

That engine may very well be marked as you say, but I don't think you should buy ANYTHING for a 1PE40QMB and expect it to fit that engine, just trying to save you some frustration, and money here. I did find this page I think will make you verry happy! Check out the last item on the link, and good luck! www.scrappydogscooters.com/Geely_D1E41QMB_2T_parts.html

Are those pics from somewhere else that you've found? What those pics appear to be from what I can tell are of a vertical engine with a pipe for a horizontal engine beside it. Pretty clearly showing why a pipe for a horizontal doesn't fit a vertical (not that even any horizontal pipe will fit any other horizontal motor). Look at where the attached exhaust connects, and then look where the performance pipe would need to attach.
If the cylinder is above the crank, as it is in those pics, it's a vertical. The piston travels up and down rather than side to side, as you're looking at it.
I am sorry if it is disappointing news, but what I told you in the other thread about not being able to make good use of a real tuned pipe is true. I promise you that if you did make or find a tuned pipe that really picked up the revs and high RPM power, it would ruin the scoot for you unless you only ride long distances without many stops at all. It would either fail to hit the pipe or struggle very hard to hit the pipe. That means it would have essentially no power until it eventually made it to the right RPM for the pipe to begin working and could pick up speed. It can be a headache to get a true CVT driven scoot to work well with some pipes. Trying to make a single speed chain drive work with a pipe would be a nightmare at best.
Your only hope would be something like a Phongeer street exhaust that makes good low end power. You could try contacting them (try searching for Phongeer on Facebook). They're a company from Taiwan with very little support in the US, but they make a great street exhaust. Even then, I'd never spend $150 or whatever it would be if they do make a pipe. Just for the sole reason that you could use that money and the money you could get from your current scoot to buy one that has an engine much better supported by the aftermarket that will yield much more performance much easier.
I don't mean to be a downer at all, but this is what I believe to be the truth on this matter. If you decide to continue on this path, I wish you the best and I will help what I can, but I think you will have a lot of headaches and disappointments with this one. Please let us know if you do find anything new and keep us updated on your progress.
Also, please everyone try to keep things friendly. There is no need to be insulting to one another. It gets us nowhere. What oldgeek said is 100% correct. To many, all Chinese scoots are junk. I love mine though, and support the hobby of riding and modifying them.

brent,,thanks, understand. pics are real, i took them of my scooter this morning. maybe i have some strange hybrid. the engine # is right off the crankcase casing. the exhaust exits as you see it in my pics? sure nobody modified it, i got it w/ only 54mi. if in fact it's a wate of time and $

If the stock exhaust is not restricted, you'd probably just make more noise and that would be about it. The only one of these I've been around in person had an all steel, 1 piece, exhaust. You'd have to cut it apart and mess with the innards, then weld it back up. Sometimes you can take a long drill bit and try to drill in through the tailpipe to see if you can open something up a little. Sometimes it works, sometimes it doesn't. The BBK would be much better investment of your time and money than playing with the exhaust IMO. If you don't wanna spend much or any money and just wanna play a little, maybe try checking squish and compression and see if you could remove the head gasket (use copper spray) for a little boost. Go over your carb and see if there's any room for improvement with jetting or adjustments. 49ccscoot.proboards.com/thread/372/modding-stock-mufflerIf are really ambitious and skilled... 49ccscoot.proboards.com/thread/1275/expansion-chamber-pipe-build

Good morning everybody...Let me clear up a few things: 1]I don't plan on racing this scooter 2] found it in the trash, thought I might get it running, I did, as a hobby 3] I'm not a mechanic type, just handy 4] it's just a recreational vehicle 5]My grandchildren will be visiting this spring/summer, thought it would fun for them 6] as teenagers, a lil' more power and noise would excite them, I thought. That's it, really simple. I TRULY APPRECIATE EVERYBODY'S INPUT, maybe this is the wrong forum for me.....Well as I weigh my options, Would any skilled muffler maker consider modifying my stock muffler? Naturally, you would compensated. {look at the pics at the start of this post] Are there any takers out there?

I'm not sure why this is the wrong forum for you. I assure you, you're getting sound advice. Sorry if anyone gets rude, but there is a lot worse out there on some forums. Unfortunately, we just can't change what you're working on. Wish you had found a model with a different engine and then we could give you tons of links to all sorts of parts that fit, but it is what it is.
Looking at it, I'd say just chop off a little of the outlet to the tailpipe so it's a straighter shot in, and see if you can drill a hole in whatever is behind it. That's about as easy as it gets, but sometimes it doesn't do much of anything. Beyond that you would have to take it off and chop it up and modify the internals and weld it back together. I think if you wanted something like that done you may consider talking to local muffler shops and see if they'd be willing to do anything with it. I saw some time ago that someone could do the cutting and such, but was unable to weld so they just took their pipe to a welding shop and had them seal it back up when they got done working inside.
I think it would be a good idea to try and source this local to you, mostly to save money. Just to ship the pipe both ways if you find an interested party would probably be in the neighborhood of $40. I'd almost think whoever modded it would need the scooter to do a good job. Any time I've messed with them, I do a little at a time and bolt it on for a listen before deciding if I need to do anything more. If you go too far, it will be really, obnoxiously, loud. Don't go far enough and it may not sound like you've done anything.

Why not adding a pod filter to have a more aggressive sound? Modding your airbox is also possible, like adding some unifilter inserts. I never saw performance pipe for those engines. You can take out the baffle of the stock exhaust but it's a lot of work and you may seriously loose performance. You'll need to jet your carburetor for the pod filter or for your exhaust.
It's a chain driven transmission? It will be better for you to keep this stock exhaust as the power curve is wider, and if you add a performance exhaust you'll loose a lot of power: the power curve is narrow on expansion chamber pipes. On belt driven transmission the engine RPM is constant, as there is a variator to keep the engine speed steady. Your engine RPM is varying during acceleration, most expansion chamber pipes give good power at high RPM's, so you'll loose a lot of low end power to get a little push just before you reach full speed.

Good idea Kevin. The pod filter will definitely get you plenty of noise. You'll need to figure out what main jet style and size your carburetor uses and buy a selection of jets 10-15% larger. Should be able to handle the rest with adjustments to the idle mixture and needle position. Since you like the noise, the only other downside would be that it will likely become more finicky... be affected by changes in weather more and sometimes can be hard to start when cold.

When it's hard to start on cold with a pod filter, I take a spray bottle filled with gaz and I spray some on the filter. I don't know which carburetor type are having those scooters, it might be hard to find jets for it. If you plan to use the scooter for a while and you don't want to worn out the engine with dust and particles, use a good quality pod filter. Measure your carburetor intake diameter (it should be around 28mm or around 35mm)
