I have a new 07' ec200 that is lacking in performance and after trying a JD kit
that has only helped slightly i was thinking of a different type of exhaust maybe FMF which made a big difference on my previous bike 200exc. Has anyone got any suggestions other than the exhaust ?...alltitude is upto

Re: the best pipe/muffler 07' ec200
I am not sure as to where you wwant more power. I hear the JD needle makes the bike smoother. If you need more bottom end power a switch for 13:52 gearing will help LTR power valve cover a POWER NOW PLUS POWER NOW (carb divider plates), FMF Gnarly for bottom end, and a 2K2 igntion.
As for your jetting it sounds like you could go down on the pilot one size and raise the clip up one position.,,,

As long as you get a muffler that is comparable to a stock muffler then it will have no effect on the performance. Most aftermarket companies make stock mufflers that would fit your bike though it would likely be cheaper to just replace them with stock kawasaki pipes. As to replacing them, using an impact wrench will make removal easier and be sure to use a new clamp even if the old one looks good
Screamin Eagle mufflers work well. I've been running a set on a Dyna Wide Glide for years. They're not as loud as straight pipes. They come with removable baffles, I think. It's been years since I've mess with them but they used to. Also, some pipe manufacturers made "slip on" muffler replacements. They're much better for performance too as they present the engine with a bit of backpressure that the drag pipes do not.
The most common reason for backfiring is lack of back pressure from changing the exhaust. To compensate for the flat spot you get you put in a jet kit. This leaves the possibility of more unburned gas getting into the exhaust. Honda uses Kei Hin carbs with a fuel shut off diaphragm to help limit this condition (backfiring) by turning off the fuel to the carbs during deceleration. Even stock exhaust can pop or backfire. Typically it is caused by air getting into the exhaust either past the copper o-ring gaskets in the head or leaking muffler connections from the head pipes to the mufflers. Try replacing all the exhaust gaskets and you should minimize this condition.
I have the 06 Husky TE510 so my jetting is different but I bought a JD jet kit and it has everything you need to set it up right. Check the plug and see if it is light almost white it is jetted too lean and you need to go bigger, if it is black it is too rich and needs to be smaller. A nice coco brown color is what you want to see.
Im not very familiar with your specific bike, but I do know what your problem is.cobra pipes are usually a straight-through design, meaning they have no muffler. the ones that do have a muffler usually have a very small one. smaller mufflers mean less fiberglass packing inside to absorb all of that noise. if your not too concerned about performance, then your best bet would be to go back to a factory exhaust. thats going to be the quietest one that you can use. Im sure there are also aftermarket systems available that also use a good muffler for noise control, but pretty much any aftermarket pipe is going to be louder then the factory setup. they are designed to give your engine more performance, which means less restriction for the xhaust gasses, which also means more noise due to the more open design of the pipes. Im not sure if your bike comes carbureted or fuel injected, but keep in ind that any exhaust changes made to a carbureted engine will require carburetor jetting adjustments to compensate for the change in exhaust flow. now, if you decide that your willing to lose just a tiny bit of performance for a quieter ride, then you may be able to find a used stock system on ebay for a very reasonable price. or if you want to stay aftermarket, then most companies test the sound levels of their exhaust pipes. by contacting the manufacturers, you should be able to obtain and compare the sound decible levels for different exhaust companies to find one that meets your needs.
It could be the exhaust baffles inside the pipe have given away from its spot weilding whn new, this is due to rust and off course usage.
Try to kick the exhaust pipes (gently and see if theres the same kind of nosies you get when you ride and cruise.
I am very pleased with my modifications on my Road King Classic, and to tell you the truth, I have "invested" the months, almost the years, in order to get perfect combination (from my point of view).
So, here is my recommendation:
1. Stock pipes
2. Wild Pig Pipes/mufflers/slip ons (1 3/4" baffles - not too loud, 2" baffles - quite loud)
3. Screamin' Eagle Stage One Kit (read as: more air)
4. DFO (Digital Fuel Optimizer) to adjust everything, to "help" all new parts to work in harmony. Adjustment will be done via producer's web site, in co-operation with very kind people from Dobeck Performance Forum.
Also, I have to emphasize that I did everything taking into account affordable prices.
Hope this helps.
