Hi!
My 2006 2t People silencer insides were loose. Luckily Finnish retailer of Kymco was selling rest of the stock with good discount and I was lucky to find older model exhaust with no emission system. First I removed restrictor. Direct fit, no hassle, and only plug to the loose air hose and zip tie. Well, it is slightly more louder but hardly noticed. It is quiet. I like. These things go fast and now even faster. Speedometer shows 75 km/h and that is around 65 km/h real life. Only with derestricted boss and exhaust.
