It is made in Italy by a company that makes exhaust for MOTO GP racers and others. Google GPR it. and have google translate it for you, to see more about the manufacturer. It's on an ebay store. Search ebay for the Lenas Performance store, or just put in Kymco Xciting 500, and you can find it either way Happy hunting! It is extremely light! I may see if I can possibly make the center, and the only baffle in it, removeable in mine, to make it sound a little deeper and louder! But this little voice of reason says; Leave well enough alone! Look at the inside of it before you put it on. Just hold it up to a bright light, look through, and you can see why I'm tempted to modify. Very simple. No rejetting is required. Ask seller about EFI change if you happen to have an 08. It takes a little longer to arrive, than I expected, because it has to come from Italy. 1.5 to 2weeks, if I remember right. Extremely simple bolt on. Looks so much cooler than stock 25 pounder apx. est.
Peace Out!
